interview questions technical problem solving

By Mike Simpson

When candidates prepare for interviews, they usually focus on highlighting their leadership, communication, teamwork, and similar crucial soft skills . However, not everyone gets ready for problem-solving interview questions. And that can be a big mistake.

Problem-solving is relevant to nearly any job on the planet. Yes, it’s more prevalent in certain industries, but it’s helpful almost everywhere.

Regardless of the role you want to land, you may be asked to provide problem-solving examples or describe how you would deal with specific situations. That’s why being ready to showcase your problem-solving skills is so vital.

If you aren’t sure who to tackle problem-solving questions, don’t worry, we have your back. Come with us as we explore this exciting part of the interview process, as well as some problem-solving interview questions and example answers.

What Is Problem-Solving?

When you’re trying to land a position, there’s a good chance you’ll face some problem-solving interview questions. But what exactly is problem-solving? And why is it so important to hiring managers?

Well, the good folks at Merriam-Webster define problem-solving as “the process or act of finding a solution to a problem.” While that may seem like common sense, there’s a critical part to that definition that should catch your eye.

What part is that? The word “process.”

In the end, problem-solving is an activity. It’s your ability to take appropriate steps to find answers, determine how to proceed, or otherwise overcome the challenge.

Being great at it usually means having a range of helpful problem-solving skills and traits. Research, diligence, patience, attention-to-detail , collaboration… they can all play a role. So can analytical thinking , creativity, and open-mindedness.

But why do hiring managers worry about your problem-solving skills? Well, mainly, because every job comes with its fair share of problems.

While problem-solving is relevant to scientific, technical, legal, medical, and a whole slew of other careers. It helps you overcome challenges and deal with the unexpected. It plays a role in troubleshooting and innovation. That’s why it matters to hiring managers.

How to Answer Problem-Solving Interview Questions

Okay, before we get to our examples, let’s take a quick second to talk about strategy. Knowing how to answer problem-solving interview questions is crucial. Why? Because the hiring manager might ask you something that you don’t anticipate.

Problem-solving interview questions are all about seeing how you think. As a result, they can be a bit… unconventional.

These aren’t your run-of-the-mill job interview questions . Instead, they are tricky behavioral interview questions . After all, the goal is to find out how you approach problem-solving, so most are going to feature scenarios, brainteasers, or something similar.

So, having a great strategy means knowing how to deal with behavioral questions. Luckily, there are a couple of tools that can help.

First, when it comes to the classic approach to behavioral interview questions, look no further than the STAR Method . With the STAR method, you learn how to turn your answers into captivating stories. This makes your responses tons more engaging, ensuring you keep the hiring manager’s attention from beginning to end.

Now, should you stop with the STAR Method? Of course not. If you want to take your answers to the next level, spend some time with the Tailoring Method , too.

With the Tailoring Method, it’s all about relevance. So, if you get a chance to choose an example that demonstrates your problem-solving skills, this is really the way to go.

1. Can you tell me about a time when you had to solve a challenging problem?

In the land of problem-solving questions, this one might be your best-case scenario. It lets you choose your own problem-solving examples to highlight, putting you in complete control.

When you choose an example, go with one that is relevant to what you’ll face in the role. The closer the match, the better the answer is in the eyes of the hiring manager.

EXAMPLE ANSWER:

“While working as a mobile telecom support specialist for a large organization, we had to transition our MDM service from one vendor to another within 45 days. This personally physically handling 500 devices within the agency. Devices had to be gathered from the headquarters and satellite offices, which were located all across the state, something that was challenging even without the tight deadline. I approached the situation by identifying the location assignment of all personnel within the organization, enabling me to estimate transit times for receiving the devices. Next, I timed out how many devices I could personally update in a day. Together, this allowed me to create a general timeline. After that, I coordinated with each location, both expressing the urgency of adhering to deadlines and scheduling bulk shipping options. While there were occasional bouts of resistance, I worked with location leaders to calm concerns and facilitate action. While performing all of the updates was daunting, my approach to organizing the event made it a success. Ultimately, the entire transition was finished five days before the deadline, exceeding the expectations of many.”

2. Describe a time where you made a mistake. What did you do to fix it?

While this might not look like it’s based on problem-solving on the surface, it actually is. When you make a mistake, it creates a challenge, one you have to work your way through. At a minimum, it’s an opportunity to highlight problem-solving skills, even if you don’t address the topic directly.

When you choose an example, you want to go with a situation where the end was positive. However, the issue still has to be significant, causing something negative to happen in the moment that you, ideally, overcame.

“When I first began in a supervisory role, I had trouble setting down my individual contributor hat. I tried to keep up with my past duties while also taking on the responsibilities of my new role. As a result, I began rushing and introduced an error into the code of the software my team was updating. The error led to a memory leak. We became aware of the issue when the performance was hindered, though we didn’t immediately know the cause. I dove back into the code, reviewing recent changes, and, ultimately, determined the issue was a mistake on my end. When I made that discovery, I took several steps. First, I let my team know that the error was mine and let them know its nature. Second, I worked with my team to correct the issue, resolving the memory leak. Finally, I took this as a lesson about delegation. I began assigning work to my team more effectively, a move that allowed me to excel as a manager and help them thrive as contributors. It was a crucial learning moment, one that I have valued every day since.”

3. If you identify a potential risk in a project, what steps do you take to prevent it?

Yes, this is also a problem-solving question. The difference is, with this one, it’s not about fixing an issue; it’s about stopping it from happening. Still, you use problem-solving skills along the way, so it falls in this question category.

If you can, use an example of a moment when you mitigated risk in the past. If you haven’t had that opportunity, approach it theoretically, discussing the steps you would take to prevent an issue from developing.

“If I identify a potential risk in a project, my first step is to assess the various factors that could lead to a poor outcome. Prevention requires analysis. Ensuring I fully understand what can trigger the undesired event creates the right foundation, allowing me to figure out how to reduce the likelihood of those events occurring. Once I have the right level of understanding, I come up with a mitigation plan. Exactly what this includes varies depending on the nature of the issue, though it usually involves various steps and checks designed to monitor the project as it progresses to spot paths that may make the problem more likely to happen. I find this approach effective as it combines knowledge and ongoing vigilance. That way, if the project begins to head into risky territory, I can correct its trajectory.”

17 More Problem-Solving-Based Interview Questions

In the world of problem-solving questions, some apply to a wide range of jobs, while others are more niche. For example, customer service reps and IT helpdesk professionals both encounter challenges, but not usually the same kind.

20 Technical Interview Questions to Know

Technical interviews often include questions that test the candidate’s understanding of software and how software works. It’s important to both be knowledgeable about the coding language you’ll primarily be working in and various development methodologies.

Common Technical Interview Questions

Describe the concept of a binary search algorithm and its time complexity.
What are the main differences between HTTP and HTTPS?
Explain the concept of a linked list and its advantage over an array.
What is the purpose of a code review in testing?
What are the different programming languages used in web development?
How does caching work in web development?
How would you optimize low-performing SQL code?
What is the role of a load-balancing system of architecture?
What is horizontal scaling and how does it differ from vertical scaling?
What is a service-oriented architecture (SOA)?

Here are some practice questions with answers to help you prepare.

1. Describe the concept of a binary search algorithm and its time complexity.

Binary search is a divide-and-conquer algorithm used to efficiently search a sorted array. It repeatedly divides the search space in half until the target element is found or determined to be absent. The time complexity of binary search is O(log n) , as the search space is halved with each comparison.

It significantly lowers the number of comparisons required to find an element by splitting the search space in half during each iteration. Large data sets benefit greatly from its outstanding efficiency due to its time complexity. The elegance of this algorithm rests in its capacity to quickly arrive at the intended outcome, highlighting the significance of algorithmic effectiveness in problem-solving.

The time complexity of binary search is O(log n), where n is the number of elements in the array. This is because the number of comparisons made by binary search is always log2(n). For example, if there are 10 elements in the array, binary search will make seven comparisons. If there are 100 elements in the array, binary search will make seven comparisons. Binary search is a very efficient search algorithm. It’s much faster than linear search, which compares each element in the array to the target value until a match is found. Binary search is also more efficient than other search algorithms, such as the jump search algorithm.

Given an array of integers, find the index of the target element.

Binary search code for the array described above

2. Explain the concept of a linked list and its advantages over an array.

A linked list is a data structure consisting of nodes, where each node contains a value and a reference to the next node. Unlike arrays, linked lists have dynamic size and can efficiently insert or delete elements at any position. However, linked lists have slower access times and require extra memory for storing references.

Linked lists are often used to represent data that isn’t sorted or that needs to be inserted or deleted frequently. This is because linked lists can be easily manipulated, without the need to shift other elements in the list.

Linked lists are helpful in situations requiring effective manipulation because elements can be added or removed without requiring significant data transfers. However, it's crucial to remember that linked lists have slower access speeds than arrays because they don't have contiguous memory storage and have more memory requirements for holding node references.

Here are some of the advantages of linked lists over arrays:

Dynamic size : Linked lists can grow or shrink dynamically, without the need to pre-allocate memory.
Efficient insertion and deletion : Insertion and deletion of elements in a linked list is very efficient, as it only requires updating the pointers of the affected nodes.
Memory efficiency : Linked lists can be more memory efficient than arrays for storing data that is not sorted or that needs to be inserted or deleted frequently.

You are given the heads of two sorted linked lists list1 and list2 . Merge the two lists into one sorted list. The list should be made by splicing together the nodes of the first two lists. Return the head of the merged linked list.

Merge two lists into one list code example

3. Describe the difference between a stack and a queue data structure.

A stack and a queue are both linear data structures, which means that they store data in a sequence. However, they differ in the way that they allow elements to be inserted and deleted. A stack is a last in first out (LIFO) data structure. This means that the last element that is inserted into a stack is the first element that is removed. Stacks are often used to implement recursion, which is a programming technique that allows a function to call itself.

A queue is a first in first out (FIFO) data structure. This means that the first element that is inserted into a queue is the first element that is removed. Queues are often used to implement tasks such as printing jobs or processing requests.

Given a string s containing just the characters ' (', ')', '{', '}', '[' and ']' , determine if the input string is valid.

Considering a given string of characters, 's' , that only contains the letters '(', ')', '', '', '[', and ']' , poses the task. It’s your task to validate the input string. In other words, you need to check to see if the string's bracket placement complies with the bracket pairing conventions. To make sure the sequence creates a well-balanced arrangement, it is necessary to verify that each opening bracket is accurately matched and closed by its corresponding equivalent.

Code examples showing the difference between a stack and queue

4. What are the main differences between HTTP and HTTPS?

HTTP (hypertext transfer protocol) is an unsecured protocol used for transmitting data over the internet. HTTPS (HTTP secure) is a secure version of HTTP that encrypts data using SSL/TLS protocols, providing confidentiality and integrity. HTTPS is indicated by a padlock symbol in web browsers and is commonly used for secure transactions, such as online banking or e-commerce. However, there are some key differences between the two.

Security : HTTP is not a secure protocol. This means that data transmitted over HTTP can be intercepted and read by anyone in between the sender and receiver. HTTPS, on the other hand, is a secure protocol. This means that data transmitted over HTTPS is encrypted and cannot be read by anyone in between the sender and receiver.
Speed : HTTP is generally faster than HTTPS. This is because HTTPS requires additional encryption and authentication steps, which can add some overhead. However, the difference in speed is usually not significant.
Use : HTTP is used for a wide variety of purposes, including browsing websites, downloading files, and streaming media. HTTPS is typically used for tasks that require a higher level of security, such as online banking, shopping, and email.

Here are some examples of websites that use HTTPS:

Banking websites : Banks use HTTPS to protect customer data, such as account numbers and passwords.
Shopping websites : Shopping websites use HTTPS to protect customer credit card information.
Email services : Email services use HTTPS to protect user messages.

5. Describe the purpose and use cases of design patterns in software development.

Design patterns are reusable solutions to commonly occurring problems in software design. They provide a structured approach to designing and organizing code, improving code maintainability, reusability and readability. Design patterns, such as Singleton, Factory and Observer, have specific use cases and can simplify complex software architectures. They are used to solve common problems that arise in software design, and they can help to improve the quality, maintainability and reusability of code.

There are many different types of design patterns, but they can generally be divided into three categories:

Creational patterns : These patterns deal with the creation of objects.
Structural patterns : These patterns deal with the structure of objects and how they interact with each other.
Behavioral patterns : These patterns deal with the behavior of objects and how they respond to events.

Some of the most common design patterns include:

Factory pattern : This pattern provides a way to create objects without specifying their concrete type.
Singleton pattern : This pattern ensures that there is only one instance of a class in an application.
Adapter pattern : This pattern allows two incompatible classes to work together.
Strategy pattern : This pattern allows objects to change their behavior at runtime.
Observer pattern : This pattern allows objects to subscribe to events and be notified when those events occur.

6. How would you design a scalable system for handling high traffic and large amounts of data?

Scalable systems can be achieved through techniques like load balancing (distributing traffic across multiple servers), horizontal scaling (adding more servers), caching frequently accessed data, using distributed databases and employing techniques like sharding or partitioning to handle large data volumes. There are many ways to design a scalable system for handling high traffic and large amounts of data. Here are some of the most common approaches:

Use a distributed architecture . A distributed architecture breaks down the system into smaller components that can be scaled independently. This makes it easier to add more capacity as needed.
Use a caching layer . A caching layer stores frequently accessed data in memory, which can improve performance by reducing the number of times the database needs to be accessed.
Use a load balancer . A load balancer distributes traffic across multiple servers, which can improve performance by preventing any single server from becoming overloaded.
Use a content delivery network (CDN) . A CDN stores static content, such as images and JavaScript files, in multiple locations around the world. This can improve performance by delivering content to users from a server that is close to them.
Use a database that is designed for scalability . There are many different types of databases, and some are better suited for scalability than others. For example, NoSQL databases are designed to store large amounts of data without requiring a lot of processing power.

7. What is the difference between unit testing and integration testing?

Unit testing focuses on testing individual components or units of code in isolation, while integration testing verifies the interaction between multiple components to ensure they work together correctly. Both testing are performed at different stages of the development process.

Individual pieces of code are tested in unit testing, a sort of software testing, to make sure they function as expected. Individual functions, classes, or modules can all be considered units of code. The developer who created the code being tested usually creates unit tests, and they frequently make use of a unit testing framework. Unit testing is typically performed first, followed by integration testing. This allows developers to identify and fix bugs early in the development process, when they are easier to find and fix.

Integration testing is a type of software testing where individual units of code are combined and tested as a group to ensure that they work together correctly. Integration tests are typically written by a software tester, and they often require the use of a test harness. The main difference between unit testing and integration testing is the level of granularity at which they are performed. Unit testing focuses on individual units of code, while integration testing focuses on how individual units of code interact with each other.

Here are some additional benefits of unit testing and integration testing:

Increased quality: Unit testing and integration testing can help to identify and fix bugs early in the development process, when they are easier to find and fix. This can help to improve the overall quality of the software.
Reduced development time: By identifying and fixing bugs early, unit testing and integration testing can help to reduce the amount of time spent debugging later in the development process. This can lead to shorter development cycles and faster time to market.
Reduced costs: Unit testing and integration testing can help to reduce the costs associated with software development. This is because they can help to prevent bugs from reaching production, which can save money on bug fixing and customer support.

A unit test for a function that adds two numbers together might check to make sure that the function returns the correct value for different input values. An integration test for a system that allows users to add items to a shopping cart might check to make sure that the items are added to the cart correctly when the user clicks the "add to cart" button.

Unit testing verifies particular pieces of code to make sure they work as intended. Testing an addition function, for instance, verifies that it is accurate regardless of the input. The effectiveness of integrated pieces is evaluated through integration testing.

8. What are some common software testing methodologies?

Software testing methodologies are the strategies, processes, or environments used to test software. They encompass everything from unit testing individual modules, integration testing an entire system or specialized forms of testing such as security and performance. There are many different software testing methodologies, some of the most common methodologies include:

Waterfall Model

The waterfall model is a linear, sequential approach to software development. Testing is typically conducted at the end of the development process, after all of the requirements have been defined and the code has been written.

For example, a company that is developing a new enterprise software application might use the waterfall model. The company would first define the requirements for the application, then design the application, write the code, and test the application at the end of the development process.

Agile Model

The agile model is an iterative, incremental approach to software development. Testing is conducted throughout the development process, in short cycles known as sprints. This allows for early detection of defects and changes to be made quickly.

For example, a startup that is developing a new mobile app might use the agile model. The team would start by creating a minimum viable product (MVP) and then release it to users for feedback. The team would then iterate on the app based on the feedback, adding new features and fixing bugs.

Iterative Model

The iterative model is a hybrid approach that combines elements of the waterfall and agile models. Testing is conducted throughout the development process, but it is not as frequent as in the agile model.

For example, a government agency that is developing a new website might use the iterative model. The agency would first develop a prototype of the website, then test it with users to get feedback.

The DevOps approach is a culture and methodology that emphasizes the collaboration between development, operations, and security teams. Testing is an integral part of the DevOps process and is conducted throughout the development lifecycle.

For example, A large retailer that is developing a new e-commerce platform might use the DevOps approach. The retailer would have a dedicated team of developers, operations engineers, and security engineers who would work together to develop and test the platform.

9. What is the purpose of a code review in testing?

Code reviews are conducted to ensure that the code meets quality standards, follows best practices, and is free from bugs and potential issues. They help identify defects early in the development process. A developer's code is examined by another developer or a team of developers during a code review process. A code review is performed to identify problems in the code, enhance its readability and maintainability and make sure it complies with the project's specifications.

In testing, code reviews can be used to:

Find bugs that unit tests may have missed. Unit tests are good at finding errors in individual units of code, but they can't always find errors that occur when multiple units of code interact with each other. Code reviews can help to find these types of errors.
Improve the code’s readability and maintainability. Code that is easy to read and maintain is less likely to have errors. Code reviews can help to improve the readability and maintainability of code by identifying and fixing issues such as poor naming conventions, inconsistent coding styles, and complex logic.
Ensure that the code meets the project’s requirements. Code reviews can help to ensure that the code meets the project's requirements by identifying and fixing any gaps or inconsistencies between the code and the requirements.

Software quality can be raised with the help of code reviews. Code reviews can assist in preventing problems from entering production and enhancing the overall quality of the software by identifying errors, enhancing readability and maintainability, and making sure the code complies with project objectives.

10. What are the different programming languages used for web development?

The most popular programming languages for web development are:

11. What is the difference between front-end and back end development?

Front-end development focuses on building the user interface and user experience of a website or application using technologies like HTML, CSS and JavaScript. Back end development involves building the server-side logic and database interactions using languages like Python, Ruby or Java.

Front end includes tasks such as designing the layout, creating the graphics, and coding the functionality. Back end includes tasks such as writing code, managing databases and configuring servers.

For example, a front end developer might be responsible for designing the layout of a website, creating the graphics and images for the website, and adding animations and interactivity to the website. A back end developer might be responsible for developing the code that allows users to log in to a website, add items to a shopping cart, or make a purchase.

12. Explain the concept of AJAX and its significance in web development.

Asynchronous JavaScript and XML (AJAX) is a technique used to send and retrieve data from a server asynchronously without reloading the entire web page. It allows for dynamic content updates, improved user experience, and reduced server load.

AJAX is a powerful tool that can be used to create more interactive and responsive web applications. It can be used to do things like:

Update the contents of a web page without reloading it. This can be used to create live updates, such as news feeds or stock tickers.
Get user input without reloading the page. This can be used to create forms that are more responsive and user-friendly.
Send data to the server without reloading the page. This can be used to do things like submit forms or start a new session.

Here are some of the benefits of using AJAX in web development:

Improved user experience
Reduced bandwidth usage
Increased flexibility

Overall, AJAX is a powerful technology that may be utilized to build online applications that are more responsive, dynamic, and effective. It's critical for web developers to comprehend how AJAX functions and how to apply it to enhance web apps.

13. How does caching work in web development?

Caching involves storing certain web resources (such as images, stylesheets or JavaScript files) in the browser or on intermediate servers to improve page loading speed. It reduces the need to re-download resources, resulting in faster subsequent visits or requests. It’s a technique that stores frequently accessed data in a temporary location so that it can be accessed faster.

In web development, caching is used to store static content, such as images, CSS files, and JavaScript files, so that they do not have to be retrieved from the server each time a user requests a page. This can significantly improve the performance of a website, especially for pages that are frequently visited.

There are two main types of caching in web development:

Browser caching is when the browser stores a copy of a web page in its local cache. This allows the browser to load the page more quickly the next time the user visits it.
Server caching is when a web server stores a copy of static content in its memory. This allows the web server to serve the content more quickly to users.

14. Explain the difference between SQL and NoSQL databases.

SQL databases are relational databases, which means that data is stored in tables that have rows and columns. Each row represents a single record and each column represents a single piece of data about that record. SQL databases use structured queries to access data. Structured queries are written in a language called SQL, which stands for structured query language. SQL queries are used to select, insert, update and delete data from tables.

NoSQL databases are non-relational databases, which means that data is not stored in tables. NoSQL databases use a variety of data models, including document, key-value and graph. Document databases store data in documents, which are similar to JSON objects. Key-value databases store data in key-value pairs, where the key is a unique identifier and the value is any type of data. Graph databases store data in a graph, which is a network of nodes and edges.

Here are some examples of SQL and NoSQL databases:

SQL : MySQL, PostgreSQL, Oracle and Microsoft SQL Server.
NoSQL : MongoDB, Cassandra, DynamoDB and Redis.

15. How would you optimize a slow-performing SQL query?

To optimize a slow SQL query, you can consider various approaches such as indexing appropriate columns, rewriting the query using efficient joins or subqueries, minimizing the number of returned rows and ensuring the proper use of database statistics. Here are some steps you can take to optimize a slow SQL query:

Analyze the query execution plan : Use the database’s query execution plan analyzer or EXPLAIN statement to understand how the database is executing the query. Look for any full table scans, inefficient joins, or other costly operations.
Index optimization : Ensure that the relevant columns used in WHERE, JOIN and ORDER BY clauses are indexed appropriately. Indexes can significantly improve query performance by allowing the database to quickly locate the required data.
Rewrite or refactor the query : Consider rewriting the query to use more efficient join types, subqueries, or conditional logic. Simplify the query by eliminating unnecessary calculations or redundant operations. Breaking complex queries into smaller, manageable parts can also improve performance.
Limit the result set : If you only need a subset of data, use the LIMIT clause to retrieve a specific number of rows. This can reduce the amount of data that needs to be processed and transmitted, improving query performance.

16. Explain the ACID properties in the context of database transactions.

ACID stands for atomicity, consistency, isolation and durability. These properties ensure the reliability and integrity of database transactions. Let's delve into each property:

Atomicity : Atomicity guarantees that a transaction is treated as a single, indivisible unit of work. It follows the "all or nothing" principle, meaning that either all the operations within a transaction are successfully completed, or none of them are.
Consistency : Consistency ensures that a transaction brings the database from one valid state to another valid state. It defines a set of rules or constraints that the database must adhere to.
Isolation : Isolation ensures that concurrent transactions do not interfere with each other. Each transaction is isolated from other transactions, allowing them to execute as if they were the only transaction running on the database.
Durability : Durability guarantees that once a transaction is committed, its changes are permanent and will survive any subsequent failures, such as power outages or system crashes. The committed data is stored in non-volatile storage (such as a hard disk) to ensure its durability.

Together, the ACID properties ensure data integrity, reliability, and consistency in database transactions. They play a crucial role in maintaining the accuracy and reliability of data in various applications, such as financial systems, e-commerce platforms and enterprise-level applications.

17. What is the role of load balancing in system architecture?

Load balancing distributes incoming network traffic across multiple servers or resources to improve performance, scalability, and availability. It ensures that no single server or resource is overloaded, optimizing resource utilization and preventing bottlenecks. In system architecture, load balancing is used to distribute traffic across multiple servers. This can improve performance by reducing the load on each server. It can also improve reliability by ensuring that if one server fails, the others can continue to handle traffic. And it can improve scalability by making it easy to add more servers as demand increases.

There are two main types of load balancing:

Hardware load balancers: These are physical devices that sit in front of the servers and distribute traffic across them.
Software load balancers: These are software applications that run on the servers and distribute traffic across them.

18. How would you design a system to handle high availability and fault tolerance?

To achieve high availability and fault tolerance, you can use techniques like redundancy, replication and failover mechanisms. For example, you can replicate critical components and deploy them across multiple servers or data centers. Use load balancers to distribute traffic, and implement automated failover mechanisms to seamlessly switch to backup resources in case of failures.

Designing a system to handle high availability and fault tolerance involves implementing strategies and technologies that minimize downtime and ensure continuous operation even in the face of failures. Here are some key considerations and approaches:

Load balancing
Distributed architecture
Replication and data synchronization
Monitoring and automated recovery
Regular testing and maintenance
Scalability

By incorporating these strategies and techniques, a system can be designed to handle high availability and fault tolerance, ensuring uninterrupted operation even in the face of failures or adverse conditions.

19. What is horizontal scaling, and how does it differ from vertical scaling?

Horizontal scaling is a technique for increasing the capacity of a system by adding more nodes. This is done by adding more servers to the system, each of which runs the same application. Horizontal scaling is a good option for systems that need to handle a large number of concurrent users or a large amount of data.

The main difference between horizontal and vertical scaling is that horizontal scaling adds more nodes to the system, while vertical scaling adds more resources to existing nodes. Horizontal scaling is a more scalable solution than vertical scaling, but it can be more complex to implement. Vertical scaling is a less scalable solution than horizontal scaling, but it is easier to implement.

The best approach to scaling a system depends on the specific needs of the system. If the system needs to handle a large number of concurrent users or a large amount of data, then horizontal scaling is the best option. If the system needs to handle a sudden increase in demand, then vertical scaling can be a good option.

Examples of horizontal scaling include:

Adding more servers to a cluster
Using a load balancer to distribute traffic across multiple servers
Using a content delivery network (CDN) to cache static content

Examples of vertical scaling include:

Upgrading the memory of a server
Adding more CPU cores to a server
Adding more storage to a server

20. What is a service-oriented architecture (SOA)?

Service-oriented architecture (SOA) is an architectural style that structures an application as a collection of loosely coupled services. Services are self-contained modules that perform specific functions and communicate with each other using standardized protocols. SOA promotes reusability, interoperability, and flexibility in system design.

Through established procedures, SOA services communicate and carry out certain duties. By enhancing system adaptability and reuse, SOA enables independent component evolution. It encourages the modular architecture of software, allowing for easy scaling and integration while maintaining resilience and flexibility.

Service-oriented architecture (SOA) is a software design approach that structures an application as a collection of loosely coupled services. These services communicate with each other via well-defined interfaces. SOA is a way of thinking about software architecture that emphasizes the composition of services.

SOA has several benefits, including:

Reusability: Services can be reused in multiple applications, which can save time and money.
Scalability: SOA applications can be scaled up or down easily, as needed.
Interoperability: SOA applications can be easily integrated with other systems.
Flexibility: SOA applications can be easily changed or updated.

Question 1 of 25

Tell me about the most challenging problem you have encountered in your professional career.

How to Answer

Answer example.

Everyone has had their share of challenges in their career. The interviewer knows that you are not perfect; however, they need to know that you can professionally overcome work-related roadblocks. Maybe you had a significant project that almost went sideways. Perhaps you had a conflict in the workplace that you could have handled more professionally. Explain your approach to resolving the issue and be sure to highlight the steps you took to reach that resolution.

"The most challenging problem I have encountered in my professional career was with my most recent employer. I had an incredibly important project that made up the majority of my annual budget. The client was challenging to work with as he was rarely available for comment, due to extensive international travel. I needed this deal to work out so, for the 6-month span of the project, I made my work hours reflect his time zone. This shift allowed us to communicate via Skype on a daily basis which meant a fair share of late night and early morning calls for me! It was a sacrifice, and I would do it again. I understand that sacrifices need to happen to gain successful outcomes."

"The most challenging problem that I encountered in my career was when my former company experienced a major merger. It was a lot to adjust to but, after some time, I was able to get a good pace again."

"The most significant challenge I have faced as a manager would be the labor dispute and lockout that our company went through in 2016. Many of our permanent employees are union based. We could not come to a new collective agreement, and so I ended up having to utilize a lot of temporary staffing options during that time. It was a lot of re-training, and strain on the company culture overall."

"The biggest challenge that I face as a marketer, and it's an ongoing challenge, is to manage my expectations on projects. I lean on the side of perfectionism and often put more pressure on myself than even a client would. The positive side of this; however, is that I always deliver an immaculate product."

"I'd say the most challenging problem I have encountered was when my manager suddenly resigned. I was then in charge of the department. Now, I was mostly ready for the responsibility, as the assistant manager in the department. However, I had never completed inventory reconciliation, and on the first day, this was my first task. I was asked to give projections so that our buyer could stock us for next season. I had no idea what to do, so I researched until I came up with the answer. Also, other managers in other departments helped to guide me. Ultimately the work paid off because our next season projections were perfect. Since then, I've learned more effective ways to do our inventory management and projections, but I don't think I've ever learned anything as quickly as I did that week."

"The most challenging problem I've encountered is the misstep of taking my current role. The initial pitch to me on company growth and my duties is not my reality. This factor has been a challenge to my career growth. I know that even if it was a misstep, there are lessons to be learned, and I approach each day with interest and a positive attitude to try to learn those lessons and grow professionally."

"The most significant challenge I've faced is nearly having my department eliminated due to budgetary cuts. I was lucky to have an active parent community rally behind me and the department which saved the program, in the end. The other challenge that comes to mind was getting back into the swing of teaching after taking a few years off to be home with my children. There was a learning curve on getting up to speed with curriculum and the lesson planning, but my love for teaching made it all that much easier!"

1. Tell me about the most challenging problem you have encountered in your professional career.

2. in your opinion, what makes you a great problem solver.

Employers want to know that you have a methodical approach to problem-solving. Consider the skills and qualities that help you successfully face problems. Perhaps you have a keen eye for detail. Maybe you can see opportunity when others can only focus on the issue. Share your strengths as a problem solver, and your ability to come up with innovative solutions. Strong problem solvers are: - Systematic thinkers - Open minded - Okay with being wrong sometimes - Always researching and exploring - Able to identify the core problem - Able to reverse engineer a challenge to avoid future issues - Able to come up with multiple avenues that work well for all stakeholders - Are do-ers and not worriers

"I am a great problem solver because I can compartmentalize all aspects of a problem before studying it. I also like to bring more experienced team members in to add to the solution. I will never try to be a hero and solve a complicated problem without tapping into the resources around me."

"What makes me a great problem solver is that I have a keen ability to research, read, and explore so that my recommendations are based on fact and study rather than guesses."

"I have been told that I am an excellent problem solver and I believe this is because I have a bit of an engineering mind. I can take the issue, work backward to solve it, and then use that resolution as a basis for avoiding future issues to come up. I am also a big-picture thinker which allows me to come up with various resolutions per problem."

"I am a great problem solver because I do not allow stress to cloud my judgment and mute my creativity. I am a keen observer with a great memory which allows me to recall unique solutions or ideas."

"I am a great problem solver because I draw from the experience of others, whether solicited advice or through my prior observations and then I improve upon that, where possible. My memory and years in the industry have exposed me to many types of situations and problems, so I feel I have a vast amount of experience to draw from, allowing me to be creative and effective in the way I approach any challenge. Not to mention, I'm not afraid to ask for help or advice along the way. I know that I don't know everything, so I like to ask for input when I feel I am not fully equipped to do the job alone. There is no shame in that."

"I believe I am a great problem solver because I am sure to gather as many facts as possible, I look at the problem and its potential solutions from multiple angles, and I am not afraid to make a creative decision, that might seem off the beaten path."

"I consider myself a great problem solver and believe my skills are in my emotional intelligence. I can be really in tune with the tone of the group, who is feeling what, and how they are each best reached. This skill applies to both adults and children, so it is beneficial both inside of the classroom and out! By being aware of what is at the heart of the matter and how each person needs his or her needs met, I'm able to accomplish a lot while avoiding many common landmines."

3. Tell me about a time when you discovered a problem and went beyond regular expectations to fix it.

Your innovative approach may be exciting and unconventional, but can you implement it realistically? Ideas are one thing, but putting them into practice and providing measurable results is where you can add genuine value. Think of a time you worked long hours and made sacrifices to overcome a challenging problem. Demonstrate your impact and the significance of your solution.

"During our busy tax season I noticed that one of our primary spreadsheets was not formulated properly. I am not an expert with Excel; however, with everyone being in peak stress mode - I decided it was something I could learn on my own. I watched a few online tutorials and ended up resolving the issue without the need to involve the rest of the team."

"When I worked as an admin assistant at my last job, I was in charge of purchasing office and kitchen supplies. I noticed we had been spending quite a bit of money on paper and plastic-ware. I compared the cost of disposables to the cost of buying permanent dishes and utensils for the kitchen. It turned out we were able to save the company hundreds of dollars each year by simply investing in dishes and silverware!"

"I had a staff member who was stealing supplies. Rumors were going around that she was dishonest; however, there was no evidence. I carefully waited and, after two days, the rumored infractions were caught on camera. At that point, I was able to terminate her employment. I went beyond regular expectations by gaining evidence before terminating her. I knew this would prevent a human resources issue down the road, and it also saved my company from having to pay this employee any severance pay."

"Our agency performed a major client launch last month that tested well. Upon implementing, I noticed that their new website was not functioning correctly. I wanted our client to be happy with our services, so I worked late into the night with our IT team to troubleshoot the site and ensure that by morning, there were no more kinks to work out. In the end, our client was thrilled with my dedication, and they ended up writing an amazing review online and even mentioned me in the review!"

"I managed a coat department previously and, depending on the season; these coats were very high ticket items. I had two salespeople who were consistently battling for the sale. It was unbecoming, to say the least, and impacted the department's morale. To incentivize everyone to go for the sale, I made a sales contest on non-coat merchandise. The more items they upsold, despite being a smaller sale, the more tickets they received towards various other compensation incentives like gift cards or extra time for breaks. The other sales reps felt reinvigorated, and it pushed my two coat-fighters to step outside of their perceived territory."

"In my first role, there was a regular lane of shipments that was difficult to cover. The issue didn't cause us to fall short as far as the customer was concerned. However, we were in danger of potentially having the customer poached due to waiting times. After several late nights attempting to come through for a key customer, I got tired of running in a hamster wheel. I decided to find some carriers that could assist. Long story short, after staying late many days and making some creative calls to find a backhaul, I was able to secure a new carrier, at a great rate, and keep the customer happy."

"When I was reworking lesson plans, I noticed that there was a gap between the programs and some policy. So, rather than hand them back to the team to fix, I took it upon myself to write the remaining lessons and tweak the existing ones to make them cohesive. It took about seven days of working on my own time, but it was worth it when I saw the lessons in action during the school year."

4. Tell me about a time where you had to analyze a set of data and then make a recommendation.

Talk about your attention to detail and sharp focus when it comes to data and statistics. You may not consider yourself a highly analytical person. However, this is a skill that you have indeed exercised in the past.

"I worked for a financial firm last year and had a client who was looking for investment recommendations. I gathered data on the stocks they were interested in, sorting through 12-month trends and further historical data to determine the most promising returns. The client was happy with my findings, and my manager was quite impressed with the research that I conducted."

"My boss recently asked me to make a case for Oracle on Demand versus SAP Business ByDesign. Our business was growing so fast, and we needed a new CRM fast. I called both companies who took me through a webinar and a couple of online tutorials. I then gathered the data and made an informative PowerPoint presentation. My boss was very impressed with how thorough I was, and I was happy to learn something new!"

"Each time I onboard a new client, I analyze a set of data before I make any recommendations on their strategy. This data includes their current analytics, primary sales sources, key customers, and more. I have a formula that I follow for the most part to help me assess and then give the best strategic recommendations that I can."

"My current employer wanted to know the exact impact our social media campaigns were making. I gathered our Facebook analytics for him and created a short PowerPoint presentation from the data. My recommendation was to increase our keywords in the geographical areas where our ads received the highest click-through rates. My research and recommendations certainly helped as our Facebook reach grew exponentially."

"As department manager, I'm responsible for forecasting what our sales will be for the upcoming season so that our buyer can accurately purchase the proper inventory. I have to look at our current inventory, last year's trends, YOY growth, and what the industry is doing as a whole, especially with the impact of online retailers. I then make a recommendation and forecast that will either set us up for success or not. If I under or over forecast, we end up with not enough inventory or too much to sell through and the cost is either opportunity in missed sales, or having to discount unnecessary items. To date, I've been nearly exact in my predictions."

"When doing annual reviews with my clients, I would analyze the past year's shipments, trends, and overall data. I would then make recommendations for improved efficiencies, rates, and better service contracts in the upcoming year. I would make not only carrier recommendations based on service level and pricing, but also made suggestions on new routes or ways in which we could be creative, like consolidating the shipments in our warehouses, to save cost when possible. I managed two of the most significant accounts in the office, so my recommendations were fundamental to our bottom line, and I'm happy to report that they were consistently adopted, resulting in more business."

"I am responsible for analyzing the results of our unit tests given across the department quarterly. I had not only to compile the results and make recommendations as to what units to keep and what to remove for the following year but also diagnose what ineffective and how we could remedy that. This task is a critical one as it shapes the future of the department and our efficacy as teachers."

5. When a problem requires a quick solution, how do you respond?

When it comes to complex problem solving, decisions are not always readily reached. It takes practice, experience, and confidence to learn what sorts of decisions yield the best results. Walk the interviewer through your process when it comes to making quick decisions. Do you rely on past experiences? Perhaps you go with a gut feeling. Maybe you have read case studies that you lean on in these instances. Problems that require you to act quickly can be emergency situations such as knowing where the fire extinguisher is and grabbing it fast enough to put out a small grease fire in the company kitchen. Other quick decisions could be if you are asked to take on a new responsibility and are only given five minutes to decide if it's something you are prepared to take on. Going with your gut is a skill, and the more you learn to trust your intuition, the easier it becomes to make these types of decisions. Demonstrate that you are confident and able to react swiftly when the need arises.

"Our Controller recently came down with pneumonia on a week where we had a major client presentation to give. He sent me what he had prepared, and I had to fill in the blanks. As an Analyst it was a bit out of my wheelhouse, being in a client facing role, but I adapted quickly, and reminded myself that my team needed me."

"When an urgent problem arises at work, I always try to respond in a calm and assuring manner. I am a natural leader which means that my team often looks to me for answers. One instance of my fast-thinking was just last week when we had an administrative employee no-show on a significant day for us. I called a temp agency, and they had the position filled in just one hour."

"In logistics, there are often split-second decisions that can either get the freight to a customer on time or cause a shut-down of a production line. Sometimes, these decisions have to be made after hours. On more than one occasion, I've received a phone call from our central dispatch asking me how to handle a late driver. I have to remember the details of the particular shipper or receiver, my customer, and the actual load in question but also get creative with how they can make sure to meet customer expectations. Due to the urgent nature of the business, as well as the drivers, it has to be a very quick decision to be successfully resolved. Luckily, due to following my gut, I've been able to make very fast, split-second decisions in the best interest of the branch and customer."

"As a Marketing Director, I need to make a multitude of decisions, on the fly, for varying projects. I rely partially on the instinct that I have built as an expert in the marketing industry and part in past experiences that may be similar. I am sure always to exude an air of control when making decisions."

"I thrive under pressure and always have, so when I'm given a time-sensitive situation to address, I light up and get down to business. I am more impactful and even more creative when I have little time to do much besides jump in and take charge. This ability to make fast decisions is especially helpful in my role as manager when there is an inventory, personnel, or customer issue."

"Just like with negotiations, I react swiftly in emergency situations. Perhaps my skills come from my years as a parent, having to think fast and put out fires! If a quick solution is required, I will do a fast overview of the facts and make a decision based on risk factors considering the potential financial loss."

"I am certainly a take charge and tackle a project kind of gal - as a teacher and a mom, too! I feel I have a powerful and accurate intuitive sense and I follow it instinctively. It's very rarely steered me wrong."

6. When it comes to problem solving, are you a strong collaborator?

Show off your teamwork skills by giving an example of when you successfully collaborated with your coworkers. Be sure to demonstrate how you communicated your thoughts or opinions. Highlight how your contributions, or ability to ask for help, made a difference. Explain how you are a team player who enjoys working alongside others.

"Last month, I recruited a couple of coworkers to help me solve a problem for a client. We were looking at their financials, but something didn't add up, and I didn't have the analysis background that these two co-workers had. Together we molded our areas of expertise and created a bulletproof financial plan for our client. I enjoyed the collaboration and would do it again in a heartbeat."

"I am most certainly a strong collaborator! Being an executive assistant, I am often in need of strong collaboration to complete a project for the VP who I support. I love learning new things from my coworkers and those who I report to."

"I love having impromptu brainstorm sessions with my team. It keeps everyone on their toes! When an issue comes to light, I will approach the problem with the entire team and open the floor, at the end of the meeting, for suggestions."

"In marketing, it is imperative to collaborate and gain different sides of the story, and new opinions. I try to seek out my team's opinions on projects all the time. I find everyone has something to contribute and can help me see a problem or strategy in a way that I may not have ever considered."

"I would consider myself an active collaborator and believe that two heads are almost always better than one. Three is the best, in my opinion. This way the team is odd-numbered, so if there's a dispute you can take a vote on it! Multiple viewpoints are almost always a great idea."

"I am a strong collaborator. I am always willing to listen to others' opinions, hear their perspective, and work together to build a solution that will fit for everyone. I am always looking to draw from others' experience and expertise to bring about the best solution for the client and the branch as a whole. When drafting a pitch for a client, I am always sure to bring on a manager or carrier sales rep so that I will have multiple perspectives to help bring us to the best collaborative solution."

"I believe I'm a skilled collaborator and am confident that my coworkers would agree. I come to our bi-weekly department meetings full of ideas and with an open spirit, ready to collaborate with the rest of the team. We always have engaging discussions that result in great takeaways for the teachers as well as our students."

7. When you cannot seem to find the right solution to a problem, how do you deal?

Sometimes, problems just seem too impossible to solve, at first glance. Your creative problem-solving skills may be at a stand-still from time to time, and the interviewer wants to know how you deal with that. Taking a brief break and stepping away from the problem can help you to see things from a different perspective. When you are in a rut, you can waste time plugging away at something, resulting in a decline in productivity. Discuss with the interviewer how you handle being in a rut like this.

"If I am stuck on a particular problem, I will take a break from trying to figure out what's wrong and ask a coworker for advice. Getting another person's perspective when you start to feel like you're hitting a wall can help one to see a problem with a fresh set of eyes. As humans, sometimes we overthink! The biggest hurdle can be asking for help, and I am not above asking for help when I'm stuck."

"If time allows - I will sleep on it! When faced with tough decisions where an answer does not come to me easily, I will take a moment to feel the issue out. When necessary I will also bring in the opinion of the administrators in a different department."

"If I cannot come to a solution that feels right I will check in with other leaders whom I work with and, depending on the situation, my business mentor. It's important to check in with those that I admire as they have unique ideas and some have more industry tenure as well."

"As a marketer, I am hired to find the solution for others. As you can imagine, when that solution seems elusive, it is incredibly challenging for me to accept. For this reason, I love brainstorm sessions with my team. I will also look to the outside in the form of resources online such as blogs and forums by other marketing professionals."

"It can be frustrating when a solution does not come fluidly. However, sometimes trying a solution and seeing it fail, will lead you to a lightbulb moment. I am an active person, so I like to walk and talk things out. Usually, as I do that, I don't filter my ideas. This way, something slips out that I would have edited out as "ridiculous" if I were writing down a list. I have found that this free-flowing problem-solving session often leads to the most creative and impactful solutions which I would have nixed from the get-go had another not failed."

"If I'm stuck on a problem, I try to take some time away from the issue, ideally by taking a step away from the screen and get my blood flowing. Walking away seems to help me get reinvigorated and more creative. I also find it valuable to talk it out with someone, even if that person is not a stakeholder in the situation."

"If I am stuck in a rut or can't seem to figure out the best approach, I am fortunate enough that I have so many other tasks and classes that I can focus on. Usually, if I clear my mind and fill it with something else, a great idea hits me when I least expect it. If I am stuck on a problem and cannot take the time to step away, I usually rely on my students to help me shake it off!"

8. When faced with a problem, how do you decide on the best solution?

There may be more than one solution to a problem, and the interviewer would like to know how you make a final choice when you're in a situation like that. Effectively comparing and contrasting, or weighing the pros and cons, is essential when choosing the best way to solve a problem. The interviewer wants to see that you are capable when it comes to calculating risk vs. reward. Think about a time when you have compared the risk and reward to a potential solution.

"If I have a problem with multiple solutions, I always go back to the classic pros vs. cons method. I fully understand that although no solution is perfect, and some solutions offer lesser sacrifice while others pose potential loss. I have been trained to take the solution that is 'closest to the money' which means that if I am stuck between a rock and a hard place, I will choose the solution that is most beneficial to the company's bottom line."

"When it comes to problem-solving, I will always weigh the pros and cons before making a decision. I will also bounce my thoughts off of some co-workers if I still feel conflicted after that."

"My decisions are always based on three factors. One, what is best for the company. Two, what is best for our clients. Three, what will boost employee morale. Now, not all decisions will be popular with all three groups, and I do keep that in mind. In those instances, it is my job to watch our bottom line but ensure customer satisfaction at all times."

"Rock, paper, scissors! Kidding - of course! Our team will collaborate on tough decisions, and we often vote. Majority wins in our office for many creative decisions."

"When I face a problem, I am sure to draw on previous experiences both as a customer and an employee in retail. I then use these experiences to make the most informed decision that I can about the problem at hand. Generally speaking, if I've already seen or experienced a very comparable situation, I can be impactful and exact in my approach by drawing from those experiences."

"As I consider a problem and its solutions, I make a note of what my gut tells me what to do. Then I take a step back and reflect on times that I have faced the situation before. I recall the actions that I took, the outcome, and then pivot as necessary. I trust my instinct because I am heavily knowledgeable in this industry, but I believe in relying on fact as well."

"I am typically a follow-my-gut type of person, so I follow my instinct when possible. I make a note of what my initial inclination was and then I make sure to compare and contrast solutions. Once I have identified the best solution, I check in to see if it feels right. More often than not, my initial instinct is correct. Of course, I am sure to be analytical as I weigh out each decision."

9. How do you prioritize multiple projects when they all seem equally important?

Prioritizing is a skill that requires practice. There are many approaches you can take. Here are some suggestions: 1) Make a list. By thinking through and writing down each item that needs completion, you can see it on paper. 2) Mark what is urgent or essential. Take into account deadlines and meetings. 3) Order each task based on effort and estimated value. 4) Consider due dates and how long it will take to do each item. When answering this question, show the interviewer that you have a system in place that helps you to think through what needs to happen, and when. The better you can prioritize, the more productive you will be, making you an asset to their company!

"I aim to be as effective and efficient as possible and make sure I can use all minutes of a day for a project. I have a few things going at once most of the time. I am the lead on some, the delegator on others, and the reviewer on another, for instance. This way, by splitting up the work to the appropriate parties, both my team and I can be the most efficient with our time."

"I often have multiple projects due at a time, since I am the assistant to three different executives. I ask my executives to rank their need from 1-5 in the level of urgency, including its due date. I start my work on that list. If there is more than one urgent need, I will work overtime, or through my lunch, to ensure that I deliver everything on time."

"I had to utilize creative problem solving last month when we found ourselves short-staffed and unable to hire new employees due to budget cuts. I changed our schedule to include some split shifts and received approval for a small amount of overtime spending. The problem is solved, at least temporarily, until our company comes out of our spending freeze."

"In my current department, we are very systematic in our customer delivery promises; however, that is not to say that doubling up on client deliveries does not happen. When situations occur where I have to prioritize, I will do so by the size of the client and budget. It may seem unfair at times; however, our largest clients with the most significant spend always rule out."

"I prioritize based on urgency and time required for the project. I have a list of what needs to be done, by when, and how long I estimate that it will take to accomplish. I am great under pressure, but try to make sure that I don't get myself or my team into a sticky situation by not allotting enough time for any particular project."

"I love to keep running lists of everything that I need to do, big or small. Mostly because I love crossing things off of the to-do list, but also because it helps me keep track of everything. Lately, I've started utilizing a free project management software that I use to make those lists, categorize the tasks, and mark them by the level of urgency. I take care of the most time-sensitive issues first and then move along to the equally important, but perhaps less time-sensitive to-dos. I also estimate how long each task will take, so if I have a few minutes in between projects, I can tackle the quick to dos and use that time effectively, rather than use it to figure out 'what's next.'"

"I follow the tried and true practice of making lists and assigning each item a priority and tackling the list that way. I love to check things off my list, as it gives me a feeling of accomplishment. Also, I am a believer in following my intuition. If I feel that something lower on the to-do list needs to be bumped up in priority, I will tackle that right away. As a teacher, there are always a lot of simultaneous to do items, so in addition to prioritizing, I have to be good at multitasking; something I find I do quite well as both a teacher and a mom."

Marcie's Feedback

10. Tell me about a recurring problem that you run into in your current position, and how you handle it.

The interviewer wants to see that, despite this recurring problem, you take action to find a resolution. They want to make sure they aren't hiring a chronic complainer who is easily defeated! Be careful to avoid complaining about your current (or most recent) position. A recurring problem could be a glitchy software system, an employee who is regularly late, or even an unpredictable work schedule. Remain optimistic in your reply!

"A recurring problem that I have in my current position is the fact that our client management software is not user-friendly. Any entry that I need to make is incredibly time-consuming which poses a real problem when a deadline is present, or when we have clients waiting for an answer. I have found that the best workaround for this is not to allow my paperwork to build up. The more proactive I am, the better I can keep ahead of schedule."

"A problem that I am currently running into is a lack of office supplies. My boss has been running very lean, financially speaking, since our industry took a downturn. I have to time my ordering with client invoices at this point. This situation has certainly helped me to become more aware of spending and budgets, that's for sure!"

"The greatest issue in my current position is that we have so much employee turnover. It started to feel like I was constantly training new staff. I came up with an employee referral bonus program which greatly helped. For every successful referral, our employees get $400 plus another $400 after their referral stays for three months. I believe this has been successful because the quality of our employees has greatly increased."

"In my current office, we have more clients than we can handle - which is a great thing! However, it's been tough to find the best marketers to join our team because we are a small organization. This hiring situation has meant a lot of overtime hours, which I am certainly happy to do for the most part. I do look forward to working with a bigger team, like yours."

"Unfortunately, a recurring issue in my current company is employee tenure. It's just really part of the industry as we need some holiday and seasonal associates and they typically don't want to stay on, or we don't have the budget to keep them on. This turnover means we are continually becoming a new team and learning how to work with our new coworkers. Scheduling often has a learning curve with a new team, too, because you have to take into account the availability of all parties, and who works well together. That said, it's something I'm used to. I make it a bit of a personal challenge or game for myself. How quickly I can learn their available days, how fast I can learn who works best together."

"A recurring issue at my current job is lack of reliable inventory that my clients are requesting, which can be incredibly frustrating. I am working hard to land a client, get them to buy into our program, both literally and figuratively, and then we fall short of expectations when our inventory doesn't meet their standards. That said, I continue to go out, land new clients, and try to source the proper inventory for them."

"A recurring issue revolves around my lack of a classroom and the friction that can arise at times because of it. Without the flexibility of my own classroom, I sometimes find myself in an awkward situation since I have to abide by the other teacher's rules, which sometimes conflict with mine. I do my best to follow the teachers' class rules, and make sure that we have a good understanding."

11. Tell me about a time when you failed to solve a problem. How did you overcome the failure?

'Success is bouncing from failure to failure without losing momentum,' or so they say. Your resilience shines through when you can learn from your mistakes and keep going. Give an example that shows you can accept fault and learn from challenging experiences.

"I failed to meet an important deadline in my first job out of college because I didn't know how to prioritize properly. I kept letting other menial tasks get in the way rather than focusing on finishing the project. I learned how to manage my time wisely by setting reasonable goals and reminders on my calendar. This technique helped me to manage my time more effectively."

"Last month we were having issues with our GoToMeeting application, and it was right before a major client meeting. I was on a call with the service provider, trying to troubleshoot and unfortunately, did not deliver a fix on time. After the initial frustration, I decided to talk to my boss about having backups in place. Now, we have Skype, and Google Hangouts set up for these emergency situations."

"I was asked to solve our issue of employee turnover which ended up being much more difficult than I originally thought. My initial goal was to improve turnover by 70% but in the end, only reached 40% improvement. Although I did not reach my goal, I am still happy that my action plan made a difference."

"I had a customer who was not happy with my delivery, and I chose to take care of the situation without involving my boss. It wasn't that I was trying to sweep the situation under the rug, I just honestly thought I had been successfully dealing with the situation on my own. Unfortunately, I was wrong because the client sent a nasty email to my boss a short time after. I should have gone to my boss right away and filled him in. It's something that I've learned from, and I'm ready to involve my boss with every sticky client situation."

"In a previous role as a personal shopping assistant, I was tasked with taking on a notoriously difficult client. She spent a lot of money in the store in the past but was very demanding. This challenge seemed like the perfect opportunity to prove myself. A few months in, I made the misstep of mentioning something she'd complained about at an earlier date. Apparently, she was offended that I brought it up, even though I meant it very innocently. I owned up to it immediately to my manager and came up with a plan to win her back. I wrote a snail-mail card apologizing to her and let several weeks pass before reaching out in any other way. By the time I did, two months later, she was perfectly lovely, dismissed my apology as though she didn't know what I was talking about, and we moved along in a better fashion than we had prior."

"In my first role out of college, I was working to solve a lane issue with a carrier that kept falling through. I went through every solution I could come up with including pitching consistency, to leveraging my current relationships, and asking for favors. Those favors and workarounds ran out, and we fell short of client expectations. While I did all that I knew how at the time, I still fell short, and it was disappointing. In retrospect, I would have involved more people in supervisory positions earlier on in the process to learn from their shared experiences."

"The problem I've failed to solve that still keeps me up at night is a successful inclusion of one of my students with an IEP. He loves Spanish and in a one-on-one setting excels at it, but cannot handle the behavior expectations in class because he gets too excited. I've tried multiple approaches to get him to regulate, and participate, but so far nothing has allowed him to participate in the class without disrupting the other students and causing a meltdown for himself. This fact weighs on me since I want him to experience inclusion at all times. As a result, he comes to my office a few days each week, and we have our Spanish class together. I feel this exemplifies who I am as a teacher. I will go the extra mile for my students to make sure they get their fair shake at life."

12. What sources do you look to when you need to solve a complicated problem?

The interviewer wants to know that you can think outside the box, or even ask for help when you are stuck on a complicated problem. Maybe you look to a mentor or boss for advice. Perhaps you have handbooks, manuals and systems you turn to for help. Offer some relevant examples based on your industry. If you work in the medical field, you may turn to textbooks, online research, colleagues or even patient's history to find the right solution. If you work in customer service, you may ask the customer what they need to find the best way to solve the problem. Show the interviewer that you are knowledgeable and equipped to handle these types of scenarios.

"When I am faced with a complicated problem, I will look to the resources that my current company has provided me. The answer is almost always in there. If it's more of a moral dilemma vs. a knowledge-based dilemma, I will ask my supervisor for his thoughts and opinion since I value him as a mentor and expert in our industry."

"I have a variety of manuals and online tutorials that I lean to when I need to solve a complicated problem. Usually, the issues are surrounding Excel troubleshooting, so it is easy to find answers without involving anyone else and interrupting their day."

"I have a business mentor that I turn to for significant problems. She and I are in the same industry; however, she is much more tenured than I am. I recommend that everyone have a mentor. Even though I run a team of my own now, there are times when I do not have the answers."

"When I need to solve a complicated problem I will turn to marketing forums and blogs that I follow. There is a plethora of information on the internet, and it would be a shame not to take advantage of them!"

"To solve a complex issue, I will reach out to a manager or mentor from a previous role to ask them how they've handled such issues in the past. I am always ready to dive back into our handbook, but these types of scenarios are often not covered there, which is why I value a human, experiential approach. I know that there are so many folks in the industry who have so much to teach me and have probably already "been-there-done-that," so I love to utilize them as a resource."

"If there's a complicated problem, I'll write out what I think the possible solutions would be. Then, I will weigh those potential solutions against one another and list the complications that may arise as a result of each choice. Also, I am always open to input or suggestions from those with more experience than I. I will often turn to my organizations' training resources, as well as talk the problem out with coworkers or my boss."

"I have a vast cohort of teachers with whom I work currently, or have worked in the past, so if I am stuck on a problem or feel I need some additional help, I reach out to these educators. If nothing else, they're there to lend an ear and let me bounce my ideas off of them. They almost always have some real-life experience in a very similar situation. I value this collaborative, supportive group that I've amassed over the years."

13. After you implement a solution to a problem, how do you test the effectiveness of that solution?

The interviewer wants to see that you have strong follow-through skills and the ability to use data and analytics to support your decisions. The only way to test the effectiveness of a new solution is to keep a close eye on the immediate, and often longer-term, results! Depending on the situation, you can use data, run reports, and compare/contrast your findings. If you have records of the data before your problem-solving solution, you can track the results of your new solution and analyze in a month, or beyond. It can take time to see the results, so having a method for measuring them is essential. Give an example of a time you implemented a solution and found a way to measure the results to check its efficacy.

"Last year, our company was having a very high rate of turnover due to employee burnout during overtime hours worked. I implemented a third shift which alleviated the need for excessive overtime. Yes, it did increase our payroll costs by 33%; however, it decreased our turnover which was costing us more and more every year. From the analytics I have been watching, the change will pay for itself by the end of year two."

"One solution that I recently implemented was the use of Google calendar with the executive that I support. She was rarely updating her Outlook calendar because she found it to be too difficult to do on her smartphone. Since this implementation, we have minimized our crossed wires significantly! I have measured the effectiveness of this new calendar strategy by marking down any appointments that need to be rescheduled. So far, for the month, the number of reschedules is down by 80%."

"I always look at the data to gauge the efficacy of policy or new solution. I am big on numbers as they do tell the full, and true, story. I love the reliability of spreadsheets and numbers!"

"Once our team comes up with a new marketing strategy for a client we will conduct two focus groups. One test group will be on the original marketing plan and the second, on the plan that we want to pitch. The use of focus groups is the best way for us to measure if our new strategy will be effective enough to justify the changes for the client."

"I like to collect data, as well as anecdotal assessments of new policies. It's great to have data to confirm if it was or was not effective, but I am a firm believer, too, in getting the team on board. Plus, as you implement a solution, sometimes those doing the actual day-to-day work with customers or in the actual implementation have a more accurate understanding of what's going on or what could be improved. Therefore, I am sure to ask the staff how they think it's going, if it's impactful, or what they still see as an area for growth."

"To test the effectiveness of any solution, you have to be objective and see if it genuinely addressed the problem it set out to solve. Everything in our business runs on KPIs, so when we introduce any initiative, we can see how it is or is not impacting those measurements. One example of this was when I assigned specific accounts to my team of buyers, instead of just attaching as they came up. The idea was to get a buyer to become an expert on that account, their buying habits, and therefore be more effective in the long term at sourcing for their needs. At first, it didn't seem all that impactful, as the close rate was still around 42% overall. However, over the course of 10 weeks, we saw an uptick in close ratios on the assigned, dedicated accounts versus the randomly distributed ones, resulting in 53% close ratio. It's something that became so effective that other sales pods adopted it as their practice as well."

"For me, numbers play an important part in teaching but do not paint the full picture. So, after implementing a change, it is certainly important for me to collect data from our unit tests to gauge the efficacy of the lessons we're teaching and the lesson plans we are using. However, I also am sure to check-in with the students on a more regular basis to check for comprehension. Testing is only truly reflective of the way some students learn, whereas others are terrible test takers, even though they've learned the material. That is why I like to take a two-pronged approach."

14. When a major problem arises, what is your first reaction?

The interviewer wants to know if your reactions to problems reflect maturity and professionalism. How you react will significantly determine how you fit with their existing team. Perhaps your computer crashes, and you realize you may have just lost all of your hard work. Or maybe you are limited on time and have a deadline rapidly approaching. Demonstrate to the interviewer that you take a very methodical approach to problem-solving, rather than reacting impulsively when a problem occurs.

"When a major problem arises, my first instinct is to take a step back and absorb what just happened. I then go into 'brainstorm' mode, jotting down potential ways to resolve the issue. From there, I can use a pros and cons list to determine the best course of action for a fast and amicable resolution."

"I have taught myself to become much calmer with my first reactions when problems arise. Now, I will step back and review my options for solving the problem rather than allow myself to become frustrated. If I feel that I cannot solve the issue on my own, I will ask for help from my superiors."

"Depending on the situation, I will gather my resources and team and collaborate on making the necessary happen on a shortened timeline so that we can deliver our results in the most efficient manner possible. Usually, we learn something about ourselves, the team, or a more effective approach to the next problem in the process."

"When a major problem arises, my first instinct is to jump in and fix the issue. I am a do-er and also think in a reverse-engineering manner. I start with the desired result, and work my way backward from there, figuring out where the snag occurred."

"I am resistant to stress but cannot completely avoid it. When a major issue arises, I will take a quick walk, if possible, so I can best assess how to address the issue while clearing my head. Then, I get to work. I delegate whenever possible so that I can oversee the effectiveness, but am not at all afraid to jump in and do the dirty work myself."

"In the event of a significant problem or setback, my first reaction is to freeze in disbelief for a moment or two while I gather myself, then I jump into action. I know that I need to work harder and faster to recover the time and effort lost. My salesperson mind goes into overdrive until the issue comes to a resolution."

"My first inclination in the event of a major problem is to roll up my sleeves and jump in to fix it or help mitigate some of the potential blow out. This initial reaction is especially true when the problem involves a student's feelings or wellbeing."

15. What steps do you take when you have to make an immediate decision without all the relevant information?

Sometimes we have to make decisions without all of the pertinent information at our fingertips. The interviewer wants to know that you are capable of taking educated guesses and that you are confident enough in your abilities that you can make a firm decision without all pieces of the problem being present.

"When I need to decide without all of the information, I weigh the pros and cons and come up with a solution that makes the most sense. Common sense can take you a long way! Next, I may ask the opinion of someone I trust to see what they think. Even though I trust my decision-making ability, I still think it's important to get a second opinion when it comes to situations involving money or decisions that make a significant impact on others."

"Being organized, I do have a checklist that I follow on all policy-related decisions and changes. If I do not have all necessary information to make an important decision, I can usually find answers in our company resource database, or I will consult an administrator more tenured than I."

"Immediate decisions are required of me on a daily basis. For instance, what do I do when a forklift driver doesn't show up for their shift? How do I react to a chemical spill in the warehouse? I find that the most effective method for making immediate decisions is to forget about what you don't know and focus on what you do know. That's the best anyone can do, and there is no sense wasting time on the what ifs, especially in my industry when the safety of others could be at risk."

"In my current company, we have a rule always to do what will make the client happiest. So, when I am in a situation where I need to make an immediate decision on a client file, I will ask myself what I would want if I were the client. Then, I jump into action to make that happen."

"Often when a customer is worked up, I only have a piece of the puzzle to go off of, whether because they haven't given the full story, or I'm pulled in by the associate who heard the full story. In either case, it's something I'm accustomed to and deal with daily. As far as customer problems go, they tend to follow the same general pattern, so I assess quickly what category the problem seems to fall in, and go from there."

"I am a strong believer in following my gut, and for the most part, it has not steered me wrong. I try to gather as much information as possible, but when all of the pieces are not accessible, I assess the situation using my prior knowledge of similar situations, and I follow my intuition. If I'm not certain or feel conflicted, I don't hesitate to bring in another person to help me come to the best decision for the company."

"I feel comfortable making an immediate decision, even if I don't have all of the relevant information, for the most part. I have great confidence in my situational knowledge as an experienced educator. One example that comes to mind was the class when there was a behavior outburst. I immediately leaped into action to diffuse the situation the best way I knew. By acting quickly, I can prevent the situation from further escalating."

16. How do you deal with distracting coworkers who stand in the way of your progress?

Even the most well-meaning coworkers can distract you from getting things done at work from time to time. The funny and entertaining coworkers who like to chat online and send YouTube videos are often the ones who can get in the way of your productivity if you let them. How do you respond? Show off your ability to set professional boundaries, when needed.

"I typically just set a kind, but clear, boundary and tell my coworker that I need to focus. I will offer an alternate time for a catch-up, over lunch for example. It is important for the sake of workplace culture to set aside time to be social with coworkers, so I usually just let them know when I'll be available for a quick break in the day."

"I understand working relationships are significant, and I'm sure to make time for them so that I can be useful but also enjoy myself at work. With that said, I know where these relationships fall regarding prioritization of my day. I make sure that others know that, too, without being off-putting."

"I am always interrupted by my team - that is par for the course being a manager. To deal with any lost time, I will simply stay late or come to work a bit earlier the next day. My day is unpredictable, and I have accepted that fact."

"I am very open with my colleagues and will let them know if they are a distraction. Currently, I can take my work home as well so if there is a part that I cannot get past due to distractions; I will take a day to work from my home office."

"I try to make the workplace as fun as possible, within reason. I love to make it a place people want to go to, instead of dread. That said, there are always the people that ruin it for the rest of the team by taking advantage. To combat this, I make it very clear what the expectations of allowed and prohibited behaviors are, and am sure to reinforce those expectations."

"There are always going to be co-workers who are there for the gab, rather than the work, or who are content just being in their position with no intent of advancing through the ranks. Early in my career, this bothered me. Why weren't they motivated to grow and learn? Then, I realized that it's important to have those people since a company can't have all its people always vying for the top. If there's a distracting coworker, I try to make my priorities clear and engage kindly and courteously with them as humans, and then get back to work. I am sure to remain friendly, while also firm, as needed, to communicate that I am here for work first as a priority."

"Very rarely do I find that my coworkers successfully distract me- even in a department meeting, I find I'm able to remain on task. I was always taught to ignore the behavior you wish to cease. If my coworkers are distracting and seeking attention, I try to ignore it as much as possible and only address it when it's detracting from a productive work environment."

17. Tell me about a time when you had to troubleshoot to solve a problem.

Troubleshooting is like reverse engineering - it takes skill, effort, and patience. You have to understand the problem to know how to work backward from it to find a solution. Knowing how to solve problems with technical equipment is always a solid skill, and a great way to demonstrate your example. Show that you are insightful in your approach.

"Last week, while operating the ultrasound machine, I was receiving a repeated error. I entered in a few different codes, but that didn't solve the issue. I then did a hard reset, removing all power sources. Then, I referred to the online manual for additional suggestions. It took a little time and patience, but I was able to resolve the issue without calling a technician."

"We do not have an IT department in my current office so whenever an issue arises, I am the person that my team calls. Troubleshooting is fun for me - it's like a new challenge every time. Google and IT forums are often my best friend!"

"We had a major complication in our system and our entire production line shut down. Our network administrator could not be reached so I had to go old-school and manually enter the orders so that my team could continue with production. The entire debacle lasted half of a day, and my system worked well as a placeholder."

"One of our clients called me in a panic, saying that Facebook rejected their ad campaign that we so carefully crafted. I researched on ad policy forums and learned that it was not approved because we did not set our demographic targets to people only over the age of 21. The ad was for a craft beer company, and we did not put into consideration the legal age in most states. Once I was able to narrow down the issue, I tweaked the ad, and it was approved."

"One horrific day at work, our systems went down entirely. We had no backup for how to check customers out, so I had to dig in the deep recesses of the back room and find the card imprint machines, and we wrote out tickets by hand and made imprints of the cards. I tried all the usual tricks to get our registers up, but couldn't get them to come online as it was a network error. I found the way around it with the handprint cards and then opening the cash drawer with a key."

"In a troubleshooting situation, I approach it like a maze and work backward. There are usually multiple factors contributing to any one issue, so I try to discern what they are, weigh those out and try to conclude what the potential best solution is. As far as technically speaking, my go-to in many situations, as rudimentary and childish as it may be, is often turn it off and turn it back on. Ha. I know it sounds too simple, but it often works best."

"I do everything I can to test out the technology before I bring it into the classroom- the day is so packed that we don't have any time to spare on figuring out technology if it acts up. I also always have a backup plan in mind in case the smart board or whatever we're utilizing that day doesn't cooperate, so we don't lose precious learning time." However, I believe that troubleshooting applies to more than just technology. Problems that occur offline also need troubleshooting as they arise, including figuring out a lesson plan and how it works or doesn't. It's all about working backward to see what issues, if any, may arise in its implementation during a dry run. By preparing in advance and being aware of what issues may come up, I'm able to flush out problems that would have otherwise arisen during the class time. "

18. Tell me about a time when your analysis of a problem was deemed to be incorrect. What would you have done differently?

Everyone makes mistakes when analyzing a situation. The interviewer isn't concerned with perfection; instead, they want to know how you deal the aftermath of rejection! Sometimes you can't correct your mistakes, but you can certainly learn from them. Highlight your ability to learn from your mistakes and move on, professionally.

"It was my first job as a physician's assistant, and I was trying to diagnose a patient who had severe pain in her abdomen. After running some tests, the doctor and I believed she was suffering from a gallbladder problem. We treated her, but she came back to the ER a week later. It turned out she had a problem with her pancreas. Even though we misdiagnosed her initially, we were able to use this mistake to help us identify the real problem. I've learned that sometimes making a mistake is a part of the process of solving a more complicated problem."

"I was asked recently to work on balancing an accounts receivable report. Math is not my strongest suit; however, I was confident in my ability to make it happen. Through a bit of research, I carefully worked on the document and was quite proud of my result. It turns out, I skipped a few important steps, and my work was, in fact, incorrect. I took it as a learning opportunity but also realized that my strengths are in other areas of business. I should have asked for the project to be placed with someone else, but I do not regret trying."

"We had incredibly high turnover rates when I first started in my current role. Going in guns blazing, wanting to make a strong first impression, I did a complete overhaul of the training manual thinking that was the problem. It turns out the training manual was just fine. The culprit to the turnover was one employee who was a complete bully on the job. The moment I terminated that person, the issue was solved. At least now I have a fancy new training manual! Moving forward, I now poll my team regularly for job satisfaction. I encourage a transparent workplace culture where people feel safe bringing their issues to me."

"I had a client, earlier in my career, who was not seeing the same results from their Facebook advertising as they once did. I changed the headlines, increased the budget, and even did multiple A-B tests. What I failed to see were the strategic algorithm changes that Facebook had made, which directly affected the visibility of my clients' ads. Now, I have alerts and subscribe to a couple of blogs solely dedicated to these changes, so I never miss a beat."

"Unfortunately, this happened not too long ago where I misjudged a customer complaint. The associate needed to escalate the conflict to a manager but did not accurately portray the customer's concern, and I jumped into action based off of the limited information given. Due to not gathering enough information from the customer herself or clarifying the misunderstanding with the associate, I took a misstep with the customer and did not resolve the issue as quickly as I would have liked. Ultimately, I was able to clarify the situation and get to a resolution that worked for everyone, leaving the customer happy. However I have some regrets. It was a learning process, and something I have been sure not to repeat since. Were I to do it again, I would clarify the situation with the customer, rather than taking the associate's word for it."

"When pitching an existing client on increased volume next year, I had made a recommendation on the most effective carrier for a lane. I based this recommendation on historical data and projected future rates. However, a merger occurred after the time of the pitch, and their prices skyrocketed since they were the only viable carrier for that area. Without competition, they didn't have to remain competitive in their rates. While I could not have predicted the merger, I could have quoted out with a higher margin on our part so that if there were some snag like this, we are covered. Since we lock in the rates for the customer, we took a loss each time they moved freight this way. As a backup method, whenever possible, I attempted to send the freight another way, so that we would lose some money but not take as large of a hit. That was a big learning experience for me and has helped me be better prepared to pitch other customers in a more effective, CYA type way."

"While teaching, the kids told me that I needed to quiet down at one point. I assumed it was the teacher whom I shared a wall with, that planted the seed, which was irksome. This type of situation had happened before. This time, however, I was wrong. I asked her to avoid delivering messages to me through the students, and she said she had not. Apparently, the students knew she had a headache that day, so they were all watching their volume level. I was glad that I did address the situation with the teacher, but made sure not to be accusatory or make assumptions about motives again."

19. Tell me about the most challenging aspect of your previous job. How did you overcome it?

Sometimes the most significant workplace challenge is a difficult task that puts you outside of your comfort zone. It could be something that requires skills you haven't mastered yet or qualities where you are not the strongest. Explain to the interviewer why it was difficult but be sure to spend more time highlighting the actions you took to overcome the challenge.

"The most challenging aspect of my last job was troubleshooting some of the older technology. We needed some serious upgrades, but they weren't in the budget. Learning how to work around this problem was quite a challenge, but I learned how by referring to old manuals and online forums. I ended up to become one of the stronger users of this program, in our entire office! I quickly became the go-to person when anyone had questions about the technology."

"In my current role, we have global offices that span four time zones. It is an incredible challenge to be continually calculating the difference in my mind when I call or email on updates for projects, for instance. I now have each locations time added to my desktop, my smartphone, and four individual clocks on my wall. These small and inexpensive changes made all the difference."

"The most challenging aspect of my previous job was the constant need to pivot when it came to trends in the industry. We would gain footing, and then the next greatest product would arrive. It made it difficult to feel loyalty to any of it. I started to express loyalty to the company's ability to discern great products instead of narrowing in on the products themselves. This shift in thought helped with mine and my teams' performance when it came to sales."

"My previous role was with a small agency where budgets were always a concern by the clients. Although I liked the clients, they were usually independent businesses with less than ten employees. They had a hard time thinking big-picture. I overcame this by coming up with a questionnaire that would address their greatest pain points and needs for their business. I would then focus on their small goals versus what I felt their company could be. Some business owners are more comfortable being comfortable, versus ruling the world, and that's okay! I just needed to wrap my marketing brain around that."

"The most challenging part of my prior role was navigating the landscape as the newest manager on the team. I needed to work on gaining the trust and respect despite my being green. I worked hard to build individual relationships with each associate and forge a bond with them. I also shared information about myself, including my experience in the industry, and who I am as a person. I know that this made me more human, approachable, and also solidified my credentials, so I know how to get the team on my side."

"The most challenging part of my previous job was relying on another team to be efficient. I am all for teamwork, but for me to be paid, this team needed to deliver timely and quality work. Meanwhile, their goals and metrics remained disconnected to any sales outcomes. This situation made it tough to motivate them. In the short term, I sat down with them and explained why it was vital for myself them, and the company that we work together on the same timeline. I incentivized them with coffee or store gift cards. Bigger picture, I sat down with the management of both teams and shared the issues we were having, suggesting a solution that would tie their KPIs and financial incentives to our outcomes, to make them invested. In the end, the short- and long-term approaches proved useful."

"I think the most challenging aspect of my current job is the fact that I share a classroom with another educator. Without having my space, other obstacles come up such as teachers trying to influence how I run my class, or them holding small conversations with their aides during my teaching time. I make sure to address this up front with the classroom teachers- that while it is also their room, please treat it as though it were mine during the 40 minutes that I am teaching. If there is ever an issue, I am sure to address it quickly and directly, so we can move past it."

20. When faced with a problem, are you more likely to jump into solving it, or are you the type to carefully assess the issue first?

The interviewer would like to know more about your problem-solving skills, and your personality. Discuss how you tackle problems when they arise, and keep your answer work-related if you can. Whether you are the type to jump right into solving a problem or you are more methodical in your approach, highlight to the interviewer that you are capable of handling issues professionally while using sound judgment.

"When faced with a problem, I am more likely to jump right into solving it. I believe that you cannot leave a problem to fester or become bigger than it already is. You have to take ownership of the issue, and involve yourself in the resolution right away. With that said, I am responsible for my decision making and certainly don't jump in blind. If I am unsure of what action to take, I will ask my leader for advice."

"I am careful and calculated in every step taken when it comes to problem-solving. This effort is because as an administrator, one error in judgment can throw off the timing of an entire project. I would say that I am the particular type who thoroughly assesses situations."

"As a manager, responsible for a team of 18 individuals, I need to be very calculated in most decisions that I make. I cannot act on the fly, or by emotion alone because others are relying on me."

"In marketing, I feel that I often have to do both. Some smaller decisions simply cannot be over-thought and others, especially when it comes to strategy, will need extra thought. I can provide both sides when appropriate."

"I think it depends on the situation at hand, honestly. In a familiar situation, I am ready to jump right in and tackle the problem. However, when the stakes are high, or tension is high, I am more inclined to take a step back, slow down, and be more tactful in my approach."

"I'm a "roll up my sleeves" kind of person. I see a problem, envision a solution, and begin to tackle it, figuring it out as I go and asking for help along the way. I think it can become a 'bury your head in the sand' issue, or the team will have the bystander effect, thinking someone else is going to take care of it, so I jump in and take action. I rally the troops, gather the appropriate supplies or resources as needed, and get to work."

"I'm the type of teacher who jumps in, head first and gets the work done. I know that the longer I wait to address a problem, the bigger it becomes, so I make sure to get right to it. This approach applies to interpersonal issues as well as curriculum missteps."

21. Give me a recent example of a valuable lesson you learned from a problem you faced at work.

One of the best aspects of problem-solving is that you always have the opportunity to learn from the experience. Seeing problems as opportunities to grow, is what makes you an excellent employee! Show the interviewer that you can learn valuable lessons when there is a problem at hand. Use a work-related example, if you can.

"Last month our sales team was facing a major challenge when we lost one of our primary distributors. I took action and started cold-calling, other potential distributors. I brainstormed with my team in some other ways that we could avoid a negative impact on our bottom line. We were quite successful in our recovery, and I would say that the biggest lesson I learned from the experience is that you are often only successful if you have motivated people in your corner."

"The most valuable lesson I learned from problem-solving at work is that not everyone will see your solution as the best one. Accepting change is difficult for some people, so I have found that not everyone will be on board right away."

"I recently had an employee express their disinterest in the job and the company. Rather than coach them out, I selfishly wanted to 'save' the employee. I put in extra hours mentoring and training her, just to see her quit anyways. It's a valuable lesson as a manager to put your energy into those who want to be there. Other efforts are often just a temporary fix for the inevitable."

"Marketing is always shifting so I often learn new, valuable lessons. One lesson I recently learned was to double check the documents that I send out for any needed updates. A lot of the manuals and how-tos that we send clients are evergreen; however, some are not. I accidentally sent an old social media guide to a client, and they ended up being incredibly confused. My lack of attention to detail at that moment was a bit embarrassing but lesson learned!"

"A recent learning experience was when I misjudged what the customer was upset about, and I didn't take the time to learn what it was that she was looking for. It reminded me to slow down, go back to the basics, and not assume that all situations fit the mold of the 'typical' customer. It was a perfect reminder that though I've seen most everything, I need to remember that each person and situation is unique."

"A recent valuable lesson for me has been not putting all of my eggs in one basket, as the old saying goes. Over 64% of my sales came from one group of stores, and they've always been a big contributor to the entire company's sales numbers. However, they were put on "hold" recently by their corporate, due to some restructuring issues. This event threw me for a loop. I was in real danger of not hitting my monthly sales target, and therefore I would have fallen short on my quarterly quota as well. I had to work extra long hours and hustle my other clients and fence-sitters to get them into "buy" mode to make up for the void in my numbers. It took a ton of effort, long nights, and creative pitches, but I was able to make up for the gap. I learned just how important it is to diversify my portfolio so that I don't find myself, or the company, in this position again."

"When working on curriculum development, I learned an important lesson. Two of our teachers wanted to keep a lesson in, because of personal connections to the lesson, but the other three were quite against it, with me being the uncertain one. I saw the validity in both sides. So, rather than find ourselves with a divisive issue on our hands, I proposed that we have a "freebie" lesson when we each got to pick one that we thought would culturally enrich our students. I learned that by thinking outside of the box, the team and our students would all benefit."

22. When change occurs in the workplace, it can create new problems. Do you see these as inconvenient problems, or opportunities to learn?

When a change occurs in the workplace, often problems arise due to new implementations and procedures, or unforeseen kinks needing to be worked out. Do you approach these problems positively or do you resist the change? Talk to the interviewer about how you can adapt to the inevitable issues that come with the change in the workplace.

"I fully understand that when the change occurs in the workplace, some new problems may arise because of it. I embrace workplace change because it often gives me the opportunity to learn a new skill or even teach a colleague a new skill."

"As an executive assistant, I see change all the time. Policy changes, travel changes, issues in scheduling, and the like. Although they are often inconvenient or threaten to throw my day off, I am always prepared with a Plan B. Each time these situations occur, I learn something new."

"Change is inevitable when you work with people because you cannot control everyone's reactions in a day, or whether they even show up to work. Recently I had a major shift in my team and, overnight, went from being completely confident in my team to the need of reassessing our strategy. I saw this as an opportunity to stretch outside of my comfort zone. I embrace change and learning opportunities."

"One change that we always go through in this industry are shifts related to social media platforms and online trends. These tools are ever evolving, and when you think you have it - poof - changes are made. I don't mind this, however. I believe that each shift is a chance to learn something new."

"I like to approach every day and situation as an opportunity to learn and grow, so even though it's uncomfortable, I like to think that there's something valuable to take away from any situation that involves change."

"I'm all about taking everything in stride and jumping on opportunities for growth and improvement. My latest job has been a year-long exercise in that: a start-up that pivoted entirely from the direction it had been going in when I was brought on, with an entirely new team and even intended client base. I decided to take it as a growth opportunity. I took a deep breath, rolled up my sleeves, and got to work learning and adapting to the new product, clients, and management. I think that the experience will serve me well in the future since I became quite flexible and learned a lot about myself and sales in the process."

"I am adaptable to change. As a teacher, I have to be open to change! Nothing stays the same in education and students challenge everything. I am capable of pivoting when needed and am not thrown off my game, easily."

23. Rate your problem solving skills from 1-10. How do you justify your rating?

The interviewer wants to know how you would rate your problem-solving skills. Of course, you want to give yourself a healthy rating; however, it's crucial that you remain realistic. Try to avoid giving yourself a 10, and nobody is perfect, and you do not want to come across as overly confident or someone who has no room for feedback and improvement. Alternately, avoid giving yourself too little credit. You do not want to paint the picture that you are a problem-solving dud! Try to remain in the 7.5-9.5 range while staying honest and accurate. Everyone has room to learn and improve! Be sure to justify your score as well.

"I rate my problem-solving skills as an 8/10. I will, on occasion, have times when I am not as efficient as I would like to be but all in all, I do feel that my problem-solving skills are above average. My supervisor and co-workers will attest to my fast reflexes when a problem arises, and they would also say that I remain calm under pressure."

"I will rate myself an eight because I value problem-solving but, just like most people, I have things to learn. Some ways to ensure that I can effectively solve issues are by utilizing multiple knowledge resources when looking for answers."

"I will rate myself an 8.5 because I consider myself a strong problem solver, especially when it comes to important matters that affect my team. Solid problem-solving skills are the foundation of success in business. I am always striving to be a better problem solver, so I leave the rest of the scale as an aspirational measure."

"Problem-solving is at the heart of what we do in marketing. We have to solve branding and sales issues for our clients all the time. I am an exceptional problem-solver, and quite creative with my strategies. For that reason, I will rate myself as a 9/10 and always improving."

"I'd rate my problem-solving skills as an 8/10. I believe I'm always a willing learner who brings creativity to the table, no matter what the situation. I am still full of ideas on how to solve a problem, and yet I am also open to the opinion and input of others. I like to collaborate but am not afraid to take charge and make it happen. There's room for growth, which is why I give myself only an 8!"

"I would say I get a solid 8.3 on a scale of 10. Seems weird to give myself something like a .3, but I think of it as an 83%, which is a B minus teetering on a solid B. It's a solid grade, with definite room for improvement, since I'm certainly not perfect. The reason for the B-/B grade would be that I'm quick to take action and figure out the solution as I go, but sometimes I could benefit from taking a moment to pause and reflect or gather other contributors before taking action. That said, I believe I get the best outcome possible when faced with a challenge."

"I would say I'm a strong problem solver and would rate myself an 8/10. I follow my gut and problem solve creatively, but know there is still room for improvement. I think my teamwork and problem strategies highlight my strengths in problem-solving. I can hear what people find essential and flush out the things on which we can compromise. Then, I come up with a great outcome that makes the teachers happy and is in the best interest of our students."

24. What do you think might be the greatest challenges faced in this job? How will you overcome these challenges?

Even though it may seem like a dream job, the interviewer wants to know that you have realistic expectations of the role and that you will not be blindsided if problems or challenges present themselves. Keep your answer simple. It is okay to ask for clarification on the position if you do not fully understand what challenges are in store for you.

"I think the greatest challenges in this role will be to learn the proper operation of the equipment. Another challenge will be the physical aspect of the position as I will be required to stand and walk around most of the day. I will be sure to pay keen attention to training and ask questions along the way. In regards to the physical component - I will get used to the additional activity after just a couple of days, I'm sure."

"I believe that the greatest challenge in this job will be to learn the ins and outs of your systems. I am familiar with SAP; however, will need to navigate some modules that will be new to me. If you don't mind, I would like to gain a head start on these by studying online for the next weekend or so."

"As a new manager, the biggest challenge is always to earn the trust of my new team. I plan to do this by getting to know everyone through genuine interest and conversation. I do understand that solid trust develops over time, but it's important to me to get started on the right foot."

"The greatest challenge is going to be getting to know your clients and their preferences. Every client has their quirks that need to be kept the top of mind during projects. I plan to read as many project notes as possible before diving into face-to-face meetings. I intend to come across to your clients as well-prepared and earnest."

"I think the added responsibility of running one of the highest volume departments in the store will be an adjustment, but it's a welcome challenge. I am looking forward to tackling it head on and growing through the challenges, because I know on the other side of those challenges, of that responsibility, lies the biggest opportunity yet."

"I would say the greatest challenge I'll face in this role is learning the industry ins and outs to be perceived as an expert when making the pitch to new clients. I want to be sure to immerse myself in the industry jargon, attend as many seminars and conventions as possible, and I've already begun subscribing and reading the leading industry publications so that I can get into the nitty-gritty of how it all works. Of course, I will also seek out mentorship opportunities where I can learn from folks who have been in the industry for years. I find they love to share their knowledge and it gives me a leg up."

"I believe the greatest challenge faced in this new position would be getting accustomed to the new curriculum. I am accustomed to my lesson plans and the curriculum I've had a hand in developing over the last ten years, so something new will have a bit of a learning curve, but welcomed. I am looking forward to a new challenge and to tackle a new set of lessons!"

25. What steps do you take to solve a problem?

The interviewer would like to know that you understand the importance of taking calculated steps when problem-solving in the workplace. Most candidates want to sound like go-getters, and their first instinct would be to say that they jump right in. Jumping right in can cause costly mistakes and oversights. Assure the interviewer that you will workshop the issue before diving in! Here are some steps to take: 1. Identify The Problem. Proper problem solving involves ensuring that you are very clear on the nature of the problem. Be sure that you fully understand the core of the problem before trying to repair it. 2. Identify The Stakeholders. Ask yourself, what the best case resolution will be for all stakeholders, not just for yourself. Ask yourself what is best for the company, your coworkers, and your clients. 3. List Your Options. The third step is to figure out what your options are when it comes to your course of action. Write them down if you need to. 4. Evaluate Your Options. Take a look at your list of potential actions and see if you can solve the problem using just one, or a blend of them. 5. Execute! Finally, execute your well-researched action plan. Be sure to set up a follow-up time to ensure that your solution worked.

"When I need to solve a problem, I first stop to ensure that I understand the issue at hand. Once I do, I will think of potential fixes and the pros and cons of each. Whichever solution or a blend of solutions is best for the customer; I will choose that option."

"My current company is very team-focused, and we train everyone to problem-solve with "what is best for team morale" being the question at hand. I have been with the company for twelve years so most problems I have a pretty clear idea of what will work for us, but when I need to workshop an idea, I will call in my team and have a brainstorm session."

"Problem-solving in Marketing can be unique because you have to truly balance the customers' pain point with the solutions that are currently available. Also, some clients like trying new marketing methods and others want to remain conservative, using only tried and true advertising methods, for instance. When I approach a problem, I first identify the personality of the client and their business and research options from there."

"Problem-solving in a retail environment is challenging in the sense that the issue is often something that needs to be fixed immediately, like a faulty product or an upset customer. When faced with a problem, I ask questions first, to ensure that I fully understand the core of the issue. Once I fully understand the core of the problem, I can more easily troubleshoot from there."

"Every customer is different, with unique needs, so when I need to problem-solve, I am often coming across a brand new problem or a different version of a problem I have seen before. Our company is big on chasing the money, and so I have been trained that every solution I choose must have the business' bottom line top of mind. My process is to understand the issue, address who the stakeholders are, and create a solution where everyone feels they won in some small way."

"Problem-solving in the classroom is a challenge because it is often on the fly. Or, a student will ask a question in a new way and I won't necessarily have the answer! When a problem arises, I like to involve my class, have a brainstorm session, and discuss as a group what we could do. This method turns an issue into a conversation where we have the opportunity to come up with some unique solutions."

16 Common Technical Interview Questions & How to Answer Them

This list of top technical interview questions comes straight from recruiters and tech CEOs. Ace your next job interview with this guide.

16 Common Technical Interview Questions and how to answer them

While some people might not find tech job interviews nerve-wracking, for most of us (even those with Computer Science or IT degrees), the interview process is the stuff anxiety dreams are made of.

While you’ll certainly have come across some of the standard interview questions you can expect in a tech job interview (think: behavioral questions, questions about your technical skill set, certifications, knowledge of project management systems and the development process) tech interviews are notoriously unpredictable. Hello, nonsensical curveball questions. 😏

It can leave you feeling lost when it comes to preparing.

But there’s no reason to panic. Ultimately, recruiters, tech companies, and other stakeholders are interested in your communication skills and your problem-solving skills (sometimes more so than your programming know-how).

And their questions are designed to reveal how you think and work through problems — not to trip you up or embarrass you.

For this post, we compiled some of the top questions you can expect in technical interviews. To help demystify the experience, we spoke with hiring professionals who supplied key tech interview questions and some pointers for formulating answers — even to the questions nobody sees coming.

First, we’re covering the broad types of questions that CEOs and other managers tend to ask when interviewing candidates for technical positions. Then we cover more technical questions — the kind meant to test your actual coding know-how.

Common Questions Hiring Managers Ask in Technical Interviews to Find Out if You’re Right For the Job

8 real examples of technical interview questions that test your coding skills.

Is Tech Right For You? Take Our 3-Minute Quiz!

You Will Learn: If a career in tech is right for you What tech careers fit your strengths What skills you need to reach your goals

1. “What do you know about our company?”

Sound obvious? Sometimes the best technical interview questions are — and they’re more revealing than you might expect.

Alan Hattman, Manager of Talent Acquisition at Peloton Technology, has a yikes-worthy story that proves that the importance of research can’t be stressed enough: While he was looking to hire a Director of Marketing, not one but two candidates thought they were interviewing for a different company with a similar name.

“They thought we were a bike company,” Hattman says. (Peloton Technology is a vehicle technology company. The interviewees had confused it with Peloton Cycle.) “They even talked about how they used our product and everything. So those were automatic fails. Do your homework. Research the job and the company you’re applying for.”

When it comes to reading up on a prospective employer, Jenna Kass, Recruiting Manager at Tableau Software, says she always appreciates when “candidates take the time to research our company from a business standpoint.” Before you walk into the interview, find out who the company’s competitors are and gather information about their audience or customers.

The last step is to build on your research with your own expertise. ShipMonk CEO Jan Bednar asks candidates for feedback about his company’s product—specifically for changes they’d make. His ideal response “would not only explain what they would like changed but also how they would change it.”

2. “What’s the most challenging/exciting project you have done in the past two years?”

Your work should lead the way in any technical interview and Lauren Thompson, Zillow’s Communications Coordinator, says that in addition to technical specifications, Zillow’s interviewers want to see “the innovation [an interviewee] comes out with from the project.” The goal of this technical interview question? To figure out what you’re passionate about, she says.

You should start preparing for this question long before you send out resumes, and a safe bet is to dig into each of your projects as you go to focus on what parts (of web development, app development, etc.) you’re passionate about, what motivates you, and what types of work you want to do in the future.

Then, practice articulating that list, so if an interviewer asks you to explain a project from your portfolio, you’ll have more to say than a simple list of specs.

Your answer might sound like: “I love 8-bit gaming, so I developed a C++ emulator for Chip-8. It combined my interest in digital preservation with getting to dust off my Tetris and Pac-Man skills. I’m looking forward to applying some of the C++ tricks I used to more projects in the future.”

3. “What kind of tech projects do you work on in your spare time?”

If you haven’t already picked up on it, passion goes a long way in tech — almost everyone I spoke to for this article mentioned it at some point.

Kevin Hayen, CTO of Let’s Be Chefs, considers self-directed creative work a critical piece of assessing entry-level applicants and veteran candidates alike. The way an interviewee answers these types of questions shows Hayen “what in tech they are really passionate about or if they even are passionate about tech” in the first place.

It doesn’t matter what your hobby is: Talk it up with all the genuine enthusiasm you have. Like many of these questions, it’s not the actual answer that interests Kevin — he says he doesn’t care if the answer is open source, DIY, or even just playing around.

Hayen says that this question also helps him figure out “how the candidate might fit into a particular team and what ‘bonus’ skills they might bring to the company” — things you didn’t even think to add to your resume but will make you a more well-rounded applicant.

4. “Tell me about the most difficult technical challenge you’ve encountered and how you resolved it.”

Bryan Petro, COO of GetMyBoat, asks this technical interview question to make sure prospective employees can do more than check off a box when a problem is fixed. “We’re not looking for people who can just churn through bugs,” Bryan says, “but people who can understand the big picture as part of a larger product team.”

So that you’re not up all night before an interview, wracking your brain for every challenge you’ve ever faced, try keeping a log of the times your skills were pushed to their limits and how you rose to the occasion as you work on projects. You don’t need to write essays here — a few bullet points to jog your memory will suffice.

5. “What technologies could you not live without?”

Stephen Negron of LegalTech Consulting, Inc. wants to know what tech skills candidates bring to the table, of course. But after that’s out of the way, he has a different line of questioning — a list of “revealing questions” that tell him about the interviewee’s life as a techie (and potential team member).

Tell me about your computers at home. What’s your internet speed?
What are your favorite gadgets? Apps?
What kind of phone do you have?
What are your tech pet peeves?

“I really want to know if they practice what they preach, if they live the tech life, and if they have an understanding of the everyday tech frustrations,” he says.

This is a point that’s easy to overlook amidst loftier talk of expertise, but if you’re not consciously engaging with devices, apps, and websites, all the technical skills in the world won’t bridge that gap toward empathizing with the end user when it comes to designing your own products.

6. “What would you bring to our monthly bakeoff?”

“It may sound like a silly question,” says Max Schleicher, Digital Marketing Manager at Insureon, but this job interview question gives him insight into candidates that a resume simply can’t. It’s a twist on the curveball question — which usually shows an interviewee’s logic skills.

While he appreciates those questions, Schleicher wants to see creativity, social skills, and communication style. “Trust me,” he says. “You can learn a lot about someone from their baking preferences.”

There’s no wrong answer, whether it be a standard “brownies” or “double butterscotch blondies with almonds,” he says. The critical tell is whether interviewees “buy in, whether they’re excited, and how well they’re going to fit into the culture we’re working to create.”

This question has another purpose: Schleicher says that a question like this humanizes him and the company because he wants to win over the applicant, too. “We want to sell our culture and our sense of teamwork to new candidates. We want to attract candidates that buy into that,” he says.

7. “Tell me about a time you were asked to do something you had never done before. How did you react, and what did you learn?”

The key to working in tech isn’t knowing everything–that’s not even possible for multi-decade vets of the industry. For Brendan Browne, VP of Talent Acquisition at LinkedIn, this question boils down to the number one soft skill needed at LinkedIn: adaptability.

“Soft skills like adaptability are a hard thing to suss out but they’re critical for someone to be successful here,” Browne says. Projects change direction all the time, while departmental reorganizations and management shifts lead to priorities being rearranged. “Your ability to deal with these scenarios will impact where you’re best able to contribute at a company.”

As far as the best way to show your adaptability in an interview setting, Browne says he’s “looking for real answers, not the canned, stereotypical responses.”

Go with an experience from your career (a department re-org, a client changing their mind last minute) or personal life (becoming a parent, a cross-country move) that shows how you’ve been able to “adapt, persevere, and manage change.”

Not a particularly adaptable person? Don’t panic. Self-awareness is also a key trait Browne looks for. “You don’t need to pretend certain skills are your strong point if they aren’t. If adapting quickly is hard for you, that’s okay. You likely have other soft skills an employer wants (collaboration, culture fit, etc.), so play those up during your interview,” he says.

8. “How much does a first class one-way ticket from New York to Abu Dhabi cost on Etihad?”

ShipMonk CEO Jan Bednar doesn’t really expect anyone to know the answer—it’s the infamous curveball question. “Frankly,” he says, “we’d be a bit surprised if they did.” Then why ask it?

“Whether they guess $3,000 or $80,000 is functionally immaterial,” Bednar says. Instead, it’s all about the process. “What steps do they take to solve the question? Do they draw upon past experiences? Projections? General knowledge? These are the skills we want to see,” Bednar says.

(Back to Top.)

In addition to the questions above, which assess your non-technical skills more than anything — such as your software development interests — hiring managers also ask technical, knowledge-based questions to determine your technical knowledge. In other words, they have to test you to make sure you have the right skill set for the job.

Whether you’re a Python pro, a Java developer, or a jack of all trades in terms of programming languages, there are language-specific questions or general programming knowledge base questions you’re expected to know, regardless of the job description.

For this post, we scoured the Internet for common questions hiring managers ask during technical knowledge-based interviews and how to answer them.

While being able to answer these questions will benefit all aspiring developers , front end developers in particular will want to know the answers to these questions.

Interview tip: when prepping for the various types of technical interviews you might face, we recommend Googling for technical interview questions and answers for your specific area of expertise (e.g. “front end developer interview questions”) to get a good idea of the range of questions that you may be asked and to practice answering them.

Even if you don’t know all of the answers right off the bat, with practice, you’ll be on your way to acing your technical interview in no time.

1. What is the main difference between Prototypal and Class inheritance?

From Temok :

“In JavaScript, inheritance is different from a lot of other development languages. In JavaScript, the object system is based on a prototype, not the class. Objects are only a collection of value pairs and names. As far as the inheritance is concerned, there is only one construct in JavaScript: objects. Each object has a private property that comprises a link to other objects, known as the prototype of that object.”

2. What does CORS mean and how does it work?

From Mozilla :

“Cross-Origin Resource Sharing (CORS) is an HTTP-header based mechanism that allows a server to indicate any origins (domain, scheme, or port) other than its own from which a browser should permit loading of resources. CORS also relies on a mechanism by which browsers make a “preflight” request to the server hosting the cross-origin resource, in order to check that the server will permit the actual request. In that preflight, the browser sends headers that indicate the HTTP method and headers that will be used in the actual request.”

3. What is ClickJacking?

From Fullstack Cafe :

“ClickJacking is an attack that fools users into thinking they are clicking on one thing when they are actually clicking on another. The attack is possible thanks to HTML frames (iframes). Its other name, user interface (UI) redressing, better describes what is going on. Users think they are using a web page’s normal UI, but in fact there is a hidden UI in control; in other words, the UI has been redressed. When users click something they think is safe, the hidden UI performs a different action.”

4. What is the difference between let, const, and var?

“Originally, var was the only option JavaScript had for defining variables. In ES6, we got const and let as additional options. The important takeaways are:

Variables defined with const cannot be reassigned.
Const and let variables are block-scoped.
Var variables are function scoped.
Variables defined with var are hoisted.”

5. What is WCAG and what are the differences between A, AA, and AAA compliance?

From Digital Accessibility Center:

“WCAG stands for Web Content Accessibility Guidelines, which are part of a series of web accessibility guidelines published by the Web Accessibility Initiative of the World Wide Web Consortium.

Single A is viewed as the minimum level of requirement which all websites, apps, and electronic content such as documents should adhere to.
Double A is viewed as the acceptable level of accessibility for many online services, which should work with most assistive technology which is now widely available on both desktop and mobile devices, or which can be purchased as a third-party installation.
Triple A compliance is viewed as the gold standard level of accessibility, which provides everything for a complete accessible offering, including all the bells and whistles which make the difference between a very good experience and an excellent one.”

6. How do you find the largest and smallest number in an unsorted integer array?

From Faceprep :

“ Method 1 : Traverse the array iteratively and keep track of the smallest and largest element until the end of the array. Method 2 : Traverse the array recursively and keep track of the smallest and largest element until the end of the array. Method 3 : Sort the array using STL and return the first element as the smallest element and the last element as the largest element.

For example, consider the array. arr = {1, 2, 3, 4, 5} Smallest element : 1 Largest element : 5″

7. What is a closure?

From Eric Elliot at JavaScript Scene :

“A closure is the combination of a function bundled together (enclosed) with references to its surrounding state (the lexical environment). In other words, a closure gives you access to an outer function’s scope from an inner function. In JavaScript, closures are created every time a function is created, at function creation time.

To use a closure, define a function inside another function and expose it. To expose a function, return it or pass it to another function.

The inner function will have access to the variables in the outer function scope, even after the outer function has returned.”

8. What are the differences between null and undefined?

From That JS Dude :

“JavaScript has two distinct values for nothing, null and undefined.

undefined means that the value of the variable is not defined. JavaScript has a global variable undefined whose value is “undefined” and typeof undefined is also “undefined.”

Remember, undefined is not a constant or a keyword. undefined is a type with exactly one value: undefined.

Assigning a new value to it does not change the value of the type undefined.

8 Ways to get Undefined:

A declared variable without assigning any value to it.
Implicit returns of functions due to missing return statements.
Return statements that do not explicitly return anything.
Lookups of non-existent properties in an object.
Function parameters that have not passed.
Anything that has been set to the value of undefined.
Any expression in the form of void(expression)
The value of the global variable undefined

null means empty or non-existent value which is used by programmers to indicate “no value.”

null is a primitive value and you can assign null to any variable. null is not an object, it is a primitive value.

For example, you cannot add properties to it. Sometimes people wrongly assume that it is an object, because typeof null returns “object.”

Btw, null == undefined ref: history of typeof null.”

This question sheds light on a candidate’s ability to analyze the severity and impact of various problems, manage stress under pressure, and make judicious decisions that align with the organization’s objectives.

When responding, candidates should demonstrate a systematic approach to prioritization, such as using the Eisenhower Matrix (urgent-important matrix) or MoSCoW method (Must have, Should have, Could have, Won’t have), to evaluate and tackle problems. They should also cite examples from past experiences where they successfully managed concurrent issues, explaining the rationale behind their prioritization and the outcomes of their actions. It’s important to convey adaptability and a willingness to reassess situations as they evolve, ensuring that priorities are always aligned with the most current information and organizational goals.

Example: “ When faced with multiple issues simultaneously, I employ a strategic approach to prioritization, often leveraging the Eisenhower Matrix to categorize problems based on urgency and importance. For instance, I address urgent and important issues first, as these typically have immediate consequences and high impact on key objectives. Next, I tackle important but not urgent tasks, which are critical for long-term success but don’t require immediate action. This ensures that pressing matters are resolved promptly while still advancing strategic goals.

In one scenario, I was confronted with a critical system outage (urgent and important) alongside a request for a new feature implementation (important but not urgent). I immediately mobilized the team to resolve the outage, as it affected our core service delivery. Concurrently, I planned for the feature implementation by scheduling it for the next sprint, ensuring that resources were allocated effectively without compromising ongoing operations. This dual-focus approach not only restored service swiftly but also maintained progress on product enhancements, demonstrating adaptability and a keen understanding of the dynamic nature of problem-solving.”

To counteract this, I systematically integrate checks and balances into my decision-making process. This involves actively seeking out diverse perspectives to challenge my initial assumptions and ensure that a range of viewpoints is considered. I also place a strong emphasis on evidence-based decision-making, where data and facts form the backbone of the solution, rather than subjective opinions.

On one occasion, I recognized a cognitive bias towards a familiar technology that I was inclined to favor for a project. To maintain objectivity, I conducted a blind evaluation of multiple technologies, focusing solely on performance metrics and compatibility with project requirements. This approach led to the selection of a more efficient and cost-effective technology that I had not previously considered, ultimately benefiting the project outcome. Regular self-reflection and a commitment to continuous improvement in my problem-solving approach help me to minimize the influence of personal biases and make more balanced and impartial decisions.”

18. Give an example of how you measure the success of a solution post-implementation.

Evaluating the impact and effectiveness of a solution to ensure it meets the desired objectives is a crucial part of problem-solving. This question tests your commitment to continuous improvement and your understanding that a solution’s value is ultimately determined by its real-world performance.

When responding, describe a specific situation where you implemented a solution to a problem. Detail the metrics or KPIs you established to evaluate its success and how you collected and analyzed the data. Share the outcome of the evaluation and, if necessary, any additional steps you took to refine the solution. This demonstrates your analytical skills, your ability to follow through, and your commitment to achieving the best possible outcomes.

Example: “ In addressing a recent operational inefficiency, I developed a solution that streamlined the process flow. To measure the success post-implementation, I established clear, quantifiable KPIs that were directly influenced by the solution. These included throughput rate, error rate, and time to completion. I utilized a combination of data analytics tools and user feedback to collect relevant data, ensuring a robust evaluation from both a quantitative and qualitative perspective.

Upon analyzing the data, I observed a 25% increase in throughput rate and a 40% reduction in error rate, while time to completion decreased by 15%. These metrics surpassed our initial success criteria, indicating a significant positive impact. However, user feedback revealed some minor usability issues, which I promptly addressed through iterative refinements. This not only optimized the solution further but also demonstrated my commitment to continuous improvement and stakeholder satisfaction.”

19. In what way do you leverage technology to enhance your problem-solving capabilities?

Harnessing the power of technology to analyze data, automate processes, and visualize solutions is often required in modern problem-solving. This question serves to assess a candidate’s familiarity with relevant software, platforms, and methodologies that can contribute to more efficient and effective problem-solving strategies.

When responding to this question, it’s important to highlight specific technologies you’ve used to tackle challenges. Discuss how you’ve utilized software for data analysis, project management tools to track progress, or collaboration platforms to brainstorm solutions with a team. Share a concrete example that demonstrates your ability to integrate technology into your problem-solving process, and explain how it led to a successful outcome. This shows that you are resourceful and forward-thinking in your approach to overcoming obstacles.

Example: “ To enhance my problem-solving capabilities, I leverage technology by employing advanced data analytics tools that allow for a deeper dive into the root causes of complex issues. For instance, I’ve utilized machine learning algorithms to identify patterns and predict potential problems before they escalate, enabling proactive rather than reactive solutions. This integration of predictive analytics has not only streamlined the problem-solving process but also significantly improved decision-making accuracy.

In addition, I harness the power of collaborative platforms to facilitate brainstorming and idea-sharing among diverse teams. By using these tools, I’ve successfully orchestrated virtual workshops that brought together cross-functional expertise, leading to innovative solutions that might not have emerged in a traditional meeting setting. This approach, underpinned by technology, has repeatedly proven to be instrumental in breaking down silos, fostering a culture of collaboration, and driving successful outcomes in complex problem-solving scenarios.”

20. Describe a scenario where you utilized cross-functional collaboration to address a complex issue.

Cross-functional collaboration exemplifies a candidate’s ability to understand the multifaceted nature of complex issues and their capability to harness diverse expertise to forge solutions. This approach not only leads to more innovative outcomes but also exemplifies leadership qualities and adaptability.

When responding to this question, candidates should select a scenario that highlights their role in facilitating and encouraging teamwork across different business areas. They should articulate the challenge clearly, detail the collaborative process, and explain how they engaged with others to leverage their unique skills. It’s important to emphasize the outcome of the collaboration and reflect on what was learned from the experience.

Example: “ In a scenario where our product launch was jeopardized by unforeseen supply chain disruptions, I spearheaded a cross-functional task force to mitigate the risks. This involved engaging with procurement, logistics, marketing, and product development teams. By fostering an environment of open communication and shared goals, we collectively identified alternative suppliers and adjusted our production timelines.

I facilitated brainstorming sessions that leveraged the procurement team’s expertise in vendor management, logistics’ insights into transportation challenges, and product development’s flexibility in adjusting specifications. The marketing team, meanwhile, crafted communication strategies to manage customer expectations. This synergy not only resolved the immediate crisis but also resulted in a more resilient supply chain strategy. The product launched with minimal delay, and the experience underscored the value of cross-departmental agility and proactive planning.”

How to Prepare for Technical Interviews – Problem-Solving Tips + Mindset Tricks to Get You Ready

Hi everyone! In this article we're going to talk a bit about technical interviews. I'll share a few tips that, based on my experience, might help you go through these interviews successfully.

I originally wrote this article more than a year ago, before getting my first job offer as a developer.

I'm sharing this with you now because I recently went through another interview process. And I found that the same concepts and thoughts that helped me get my first job offer allowed me to pass all the interviews successfully again. 🙂

My Background

I took up coding more or less a year ago. I started learning out of pure curiosity, and as I learned more about it and was able to build personal projects, I just fell in love with it.

I got so obsessed and passionate about it that I dedicated all the free time I had to coding, reading about code, watching videos about code, and just learning as much as I possible could, because for me it was fun and interesting!

Time passed and at a point I started imagining myself working as a developer. First it was like a blurry thought, and then I started thinking about it seriously and learning about what I needed to do to get to that point.

My learning journey and the approach I took towards becoming a dev will probably be the subject of another article, but my point is that I made it! I recently got an offer for my first job as a full time developer and I couldn’t be happier about it.

And there were many things and learning experiences I had to go through to get to this point, but I’d say the toughest one – and the one I was less prepared for – was technical interviews.

What are Technical Interviews Like?

I come from a social sciences background, and most of the time, within that field, there’s nothing too “technical” to talk about during interviews. Employers normally hire you based on your experience and behavior during interviews.

But in the coding field it’s really different. Experience is valuable, of course, but employers also value projects you can show to them, theoretical knowledge about different programming topics, and, most of all, the problem solving skills you can show off during technical interviews.

In almost all selection processes I went through, there was a technical interview in which an interviewer tossed me a problem and I had to solve it live with them looking at me the whole time.

This is a standard practice for coding jobs, but I wasn’t prepared at all. I failed miserably more than once, and these experiences were some of the most embarrassing and frustrating moments in my professional life so far.

At times I felt stupid for even thinking I’d be capable of switching careers at almost 30. I thought I just wasn’t smart enough. But luckily I kept going, researched about technical interviews, learned, practiced, and kept failing until I didn’t fail anymore.

Technical interviews are tough and can be really stressful if you’re not prepared correctly. Also, even though I successfully passed a selection process, I know I still have a lot to learn about this and that I’ll need to perfect this skill to further grow my career in the future. So here are my main tips for nailing your technical interviews.

1. Prepare for the Interview

This is important for all kind of interviews, but for technical interviews I think it’s crucial. Your chances of passing these evaluations are way lower if you don’t prepare correctly for them.

Here are some ideas that allowed me to better prepare for these interviews.

Do Your Research

Find out about technical interviews in general, how are they normally organized, what interviewers ask and what do they intend to measure, what kind of problems do companies toss at you, and what are the best approaches towards interviews.

The internet is an infinite resource of knowledge, so don’t waste it! Google about everything you can and take advantage of the experience of the thousands of people who have gone through similar situations and share their experiences.

Practice Solving Problems

Problem solving is a skill just like any other. There is specific knowledge you’ll need to get good at it, but most of it is practice and getting your brain to be comfortable in that situation.

There are tons of websites that contain the types of problems you’ll see during interviews. freeCodeCamp has an amazing course designed for this. Some other cool resources are hackerrank.com , leetcode.com , codewars.com , exercism.io , app.codesignal.com , and algoexpert.io .

Solve as many problems as you can from any of these sites and you’ll start getting good at them.

And when you practice, at first it’s okay to just worry about solving the problem. But once you get comfortable enough, a great idea is to try to make your practice as similar as possible to an actual interview. And by this I mean setting a timer, explaining your solution out loud, analyzing your final algorithm and refactoring…just basically following all the steps you’d normally follow in an actual interview.

If your practice is similar to the actual situation, once you get to that situation you’ll feel more confident because in some way you’ve already been there.

Build a Theoretical Foundation

Besides actually practicing, learning theoretical concepts about algorithms and data structures is a great idea to get better at solving these problems.

Think about it as adding tools to your toolbox. The more tools and concepts you have in your mind, the more problems will sound familiar or ring a bell in your brain, and from that you'll be more able to arrive at a solution.

There are many resources on the internet, some free and some paid. A course about data structures and algorithms is pretty much a must for any programmer, so I encourage you to find a good one. Here are a couple you can start with:

Data Structures Explained
Learn Data Structures from a Google Engineer
Learn Algorithms and Data Structures in Python
Learn about Algorithms and Data Structures

Of course also theoretical knowledge about your programming language of choice and any other tools in your stack (frameworks, libraries, databases, and so on) is also very important.

Imitate Others

It’s ok to run into problems you don’t know how to solve or to come up with solutions that are not the best suited ones.

In these type of situations, or always actually, it’s a good idea to take a look at how other people solved that same problem and learn from them. What approach did they take? What ideas did they have? Did they get stuck? How did they move towards the solution?

Analyze their solution and their behavior, identify what works for them, think if that could work for you and if the answer is yes, copy them! It’s crucial that you deeply understand why their solution works and how their logic works. You want to internalize the logical approach, not the code, as that’s just an after effect.

Looking at problem solutions and videos of mock interviews is a good idea to get this kind of data.

Understand What Kind of Interview You'll Have

I mentioned the most classic type of technical interview is the one based on algorithms and data structures, in which the interviewer will give you a problem to solve through an algorithm.

But I found that there're also interviews that are mostly theoretical, in the sense that the interviewer will ask questions to measure your knowledge about a given programming language, framework, library, design and architecture patterns, and so on.

Another kind of interview is where the interviewer shows you an actual project or asks you to build one. During the interview you discuss the decisions you made to build it or implement new features/modifications on it.

Each kind of interview is different and might require different preparation, so it's always a good idea to ask the company what will the interview be based on, and prepare accordingly.

2. Breathe and Think Things Through

Once you've seen and gone through a ton of examples and start feeling somewhat confident around coding problems, it’s time to get to the deeper stuff.

Here are some tips that helped me go through the interviews successfully.

This sounds crazy right? The best approach to solving most coding problems is actually not coding, or at least not right away .

No matter how anxious or secure you are about the idea you have in mind, I find it better to always take a step back and make sure you understand things deeply before going to the details and breaking out the code.

So how do you do that?

Understand the Problem

The first step to solving a problem is actually understanding it. And to understand it, the best idea is to “make it yours”, and internalize it.

A good idea is to read the exercise twice, repeat it again in your own words, and go through multiple examples (simple ones, complex ones, examples with null or invalid inputs…).

No matter how silly, complex or simple the problem may seem, this helps you make sure you understand it properly and gives your brain data and time to come up with solution ideas.

Make Sure You Understood It

Repetitive? Yeah, but effective. Check and make sure you understood what you need to do and how your function will work.

Ask yourself, what are the inputs going to be? What will be the output? Check for edge cases. Will you always receive the same input or could you expect different formats? Do you have to be prepared for strange cases or does the exercise restrict the kind of situation you’ll encounter?

It’s better to clear out all this things before even starting to think about a solution.

Explore Your Toolbox

I said that learning theoretical concepts and practicing is like adding tools to your problem solving toolbox. When you see a new problem, it’s a good idea to explore that toolbox and see if any of the concepts or solutions you’ve used in the past could work here.

Could it help to use some sort of counter? What about implementing some sort of data structure to help you out? Could you use pointers or a sliding window? Would it be a good idea to take a divide and conquer approach? What about recursion? Could sorting the input help for anything?

You don’t necessarily have to know the exact path to take, but comparing the problem to previous patterns you’ve seen can help spark ideas in your mind.

Of course the more you practice solving problems and learning about possible solutions, the more patterns you’ll have to remember and compare.

Break Down the Problem

Once you’ve analyzed the problem deeply, hopefully you’ll have at least an idea of how to tackle it, or where to start.

A great idea here is to try to think about the different steps you need to take to get to your solution and write down those steps to analyze them, check if your logic is correct, and later use them as little memory helpers and “instructions” for you to translate into code.

Simplifying your solution through steps and specially writing them down will often help you identify flaws in your logic or cases you didn’t think about before.

This is great because you’re at a stage when it’s really easy to modify your approach or lean towards a different idea. You didn’t waste time coding or getting yourself into a maze of logic that doesn’t actually work.

Simplify the Problem

Specially when facing complex and difficult problems, a good idea is to first ignore the main difficulty of the problem and try to solve a similar, simpler version of it.

When you nail that solution, bring the main difficulty back and see if you can translate your solution to it.

Visualize the Problem

Complex problems are sometimes difficult to get your head around. Having a whiteboard, either a physical or a digital one, is always a great idea.

Visually stimulating your brain by drawing up the problem or an idea can be a good approach to buy yourself some time and see if that perspective shows you some data you didn’t notice.

Start to Write Your Code

So once you have a clear idea of the steps you’ll need to cover to get to the solution, it’s time for translating that into code. This should be the simple part if you’re comfortable enough with the language.

A thought to keep in mind here is that if you can’t remember something very specific, don’t let that hold you down – pseudo code it and carry on with the rest of the solution.

Talk to your interviewer and see if they can help you with that part, or ask if they'll let you Google it. In most cases this will be ok and the important thing will be to show that you nailed the correct logic to solve the problem.

Test Your Code

Test your solution at every step and at the end. There’s nothing more annoying than writing a ton of code and later seeing it fail without knowing the exact cause.

Test your code and your logic at every step of the solution, as this will allow you to catch bugs earlier and will save you from wasting time and effort.

Of course testing at the end is important to check if your solution actually works! So throw your function different inputs and edge cases to see if it behaves as expected.

Analyze the Solution

Once you've gotten to the solution, you’re not done yet. It’s a great idea to show your interviewer you can analyze what you did too.

Ask yourself and tell them, what’s the big O complexity of your solution? Can you think of a way to improve the performance or the memory usage of your algorithm? Is there a way to make your function easier to read and understand?

Even if you can’t think about how to code it exactly, it’s great to show them that you’re the kind of developer who is always going to look for improvements and not settle for something that just works.

Improve Your Solution

Of course, if you can find ways to optimize your solution and know how to code it, do it!

And about this, in a coding interview situation you’ll rarely come up with the perfect solution for a problem. You’re under pressure and on the clock, so it’s perfectly ok to come up with a so-so solution and then refactor it until it reaches an acceptable level.

It’s often better to show you can solve the problem even if not in the perfect way than spend all your time just thinking about the perfect solution.

Talk to Your Interviewer

Talk with your interviewer during the whole process. What your interviewer is trying to measure is your problem solving ability and your level of comfort with your programming language of choice.

That is a hard thing to measure if you don’t open your mouth and just code away.

It’s crucial that you talk to your interviewer and let them know what you’re thinking, what is your thought process, what ideas are you having, how are you understanding the problem, what logic are you going to follow with your solution and why are you making decisions.

Talk to them, ask questions, explain yourself, and if you get stuck or don’t know how to go on, explain to them exactly the thing that is giving you trouble. In most cases you’ll get some help and more importantly you’ll show them you’re actually trying to work towards a solution.

Listen to Your Interviewer

When you’re being given the problem to solve – and specially if you get tips or feedback from your interviewers – pay attention! No matter if you think you already have the best idea or if there’s something that’s driving you crazy and need to solve right now, just drop it and listen to what you’re being told.

If you don’t listen to feedback, you’re giving a very negative signal to your possible future employers. Think about it: would you like to work with someone that doesn’t listen to feedback? Besides, feedback will certainly help you solve your problem, so listen!

3. Control Your Emotions

This for me was the toughest part of the interviewing process, and it's something I didn’t really find a lot of information about when researching technical interviews.

Dealing with the anxiety and frustration these situations can provoke is hard, but also a crucial step to improve your performance.

So here are some things that have helped me in this regard.

Prepare Your Body and Mind

Interviews are stressful situations in which you have to deal with expectations and perform to reach those expectations while being judged by other people.

I’ve always felt uncomfortable in these type of situations so I’m quite familiar with the type of anxiety you might feel.

Something that helps me is try to think about it like the moment of a game for a sports player or when actors get out on stage. You normally see these people trying to warm up and focus before they start to perform, right? There’s a reason for that – and it’s that this preparation actually enhances performance and gets you ready to give your best.

It may sound stupid at first, but stretching, warming up your voice, meditating, imagining the moment in your mind and picturing yourself being successful in the moment are all things that will push you towards doing nicely in this important moment.

Be Confident

Easier said than done, right? Absolutely. Confidence for most people isn’t something you can just turn off and on, but something you build along the way and comes with lots of practice, studying, and preparation behind it.

You'll build confidence with the work you do prior to the interview, but once you’re in the moment it’s important to remember that you want to show the interviewers you have confidence in yourself as a coder and that you trust yourself to solve any problem you face.

This doesn’t mean you have to know absolutely everything and be able to solve any complex problem absolutely by yourself. Rather, it means that you won’t panic when you face something you don’t know how to solve at first, and that you have the ability to slowly analyze the problem, break it down, and work towards a solution.

Stress, anxiety, and the wish to show that you can solve the problem can make you rush more than you need to. And rushing can lead to missing key information, flaws in your logic, bugs in your code, and errors in general.

So take your time, actually, take more time than you actually need. Analyze the heck out of the problem, talk slowly, code slowly, think slowly, and remember to breath. Things are easier to deal with when you take your time and slow-mo the process.

Don’t Take it Personally – or Do...

You’ll mess up at some point, that’s a certainty. Especially in your first interviews, you’ll probably fail and feel miserable about it. It’s just the way it is, and it's a step that is needed for you to understand where you need to improve.

A key issue here is how you deal with that frustration. I could tell you to think about it as a process, to not get mad when you fail, to be patient… But if you’re an anxious and self demanding person as I am, you’ll be very frustrated when you fail, and there’s nothing you can do to avoid it.

But how do you deal with that? Do you get depressed and quit coding forever? Do you get scared of interviews and never apply for a job ever again?

Personally, I get very mad at myself when I fail at something or find out I don’t know something I "was supposed" to know. I get mad at myself for not preparing correctly or for missing things, and even though that anger feels bad at first, later on is something that pushes me forward.

I feel so bad about it that I make absolutely sure I won't fail at that again, and I practice as hard as I can to avoid being in that situation again.

Different approaches work for different people, but the thing is to handle your emotions in a way that pushes you forward and not backwards.

Learn from Your Mistakes

As it’s a certainty you’ll mess up, the smart thing to do is to learn from the errors you made and try to not make them again.

Always try to take note of the problems you were presented and your solutions, analyze your mistakes, analyze other possible approaches you could have taken, what optimizations you didn’t see, and what key concepts you didn’t remember at that moment.

Also always ask your interviewers for feedback about what you could have done better. This information is gold if you get the best of it.

If you love coding, you probably have lots of fun doing it. Never forget that, no matter the context.

In interviews, try to approach each problem with curiosity rather than fear of failing. Try to show your interviewers you’re enthusiastic about problems, because you’re probably going to work with similar stuff on a daily basis.

Plus if you’re having fun and thinking in a positive way, you’ll be more relaxed and your mind will be clearer, which of course helps your problem solving skills.

If you pass or if you fail, at the end it doesn’t matter, in the sense that your approach and behavior should stay the same.

Just as code can always be improved, so can you as a programmer. You should always keep learning, keep getting better, keep practicing, keep facing stuff you didn’t know anything about and eventually overcoming it.

So don’t get too high if you pass or too low if you miss – just keep coding and keep learning.

As always, I hope you enjoyed the article and learned something new. If you want, you can also follow me on LinkedIn or Twitter .

Tech Interview Prep: How To Ace Your Interview

You’ve applied to your dream job. You’ve passed the phone screen and screening test. Now the only thing standing in your way is the coding interview.

Are you prepared?

Even the most experienced developers can find traditional technical interviews daunting. But many emerging technical interview approaches provide an opportunity to demonstrate your skills in a real-world setting. From coding to algorithms to problem solving, technical interviews done well should test the top skills in your arsenal.

The Technical Interview: An Overview

Technical interviews are the process of evaluating developers through questions that place an emphasis on technical skills. Hiring teams use individual assignments such as coding questions, projects, or data structure problems to test and score a developer’s proficiency in key skills.

These interviews gauge a developer’s problem-solving skills and technical proficiency in various programming languages and frameworks. And they also give a glimpse into soft skills — like collaboration or communication style.

Types of Interview Questions — and How to Prepare for Them

Technical interviews come in many styles and formats. Each type of interview will test different skill sets and require a different approach to succeed. Preparing for a system design question, for example, looks a lot different than preparing for a coding challenge.

Before we dive in, it’s worth noting that there is some overlap between various types of interview questions. Technical interviews often test many skills at the same time, including algorithms, clean code practices, and language proficiency, to name a few examples, and those skills can often be showcased across a number of formats.

Coding Questions

Coding questions — sometimes called coding challenges — ask developers to write code to find an answer to a problem. Depending on the role and company, coding questions can be language-specific or allow developers to respond in their coding language of choice. Often, these questions are asked directly via an in-browser IDE that provides developers with the tools they need to provide a solution in full.

While coding questions come in a variety of formats, the strategies for answering them are similar. As you write your code, you’ll be expected to explain your solution to the hiring team. They’ll typically give you real-time feedback on the efficacy, complexity, and accuracy of your solution.

It’s important to keep in mind that a “correct” answer isn’t always enough to pass a coding interview. That’s because the approach also allows hiring teams to assess your technical communication, your code quality, and the efficiency of the solution.

Write a function int max_of_four(int a, int b, int c, int d) which reads four arguments and returns the greatest of them. There is not a built-in max function in C. Code that will be reused is often put in a separate function, e.g. int max(x, y) that returns the greater of the two values. Input will contain four integers – a, b, c, d – one on each line. Note: I/O will be automatically handled. (Language: C)
A hacker practices on HackerRank until getting to a rating of O(1) read as (Oh-one). Call the method coder.practice until coder.oh_one? becomes true. Use the until control structure. until is the logical equivalent of while not. This challenge has a one-line answer. (Language: Ruby)
If n is odd, print Weird
If n is even and in the inclusive range of 2 to 5, print Not Weird
If n is even and in the inclusive range of 6 to 20, print Weird
If n is even and greater than 20, print Not Weird
Input format: a single line containing a positive integer n. Constraints: 1 <= n <= 100.

Problem Solving

Problem-solving interview questions test a candidate’s ability to, well, solve problems. Many developers associate problem-solving interviews with technical questions such as algorithms and data structures. And while those challenges do test problem-solving skills, a problem-solving interview question can also be non-technical.

Problem-solving interviews aren’t just about getting the right answers. Equally (or even more) important is identifying a problem-solving approach and explaining it to the interviewer. This is especially true for non-technical problems which often have no right answer. Using an answering method can help with structuring your responses and explanations.

Lastly, it’s a good idea to treat every technical interview as an opportunity to showcase your problem-solving skills. Nearly every other question format tests for problem-solving skills, even if the interviewer doesn’t directly say so. Having a strong foundation in problem solving will support your performance in other interviewing moments.

Given the problem of selecting a new tool to invest in, where and how would you begin this task?
Have you ever recognized a potential problem and addressed it before it occurred?
Tell me about a time you used a unique problem-solving approach.

Algorithm questions are a type of interview question that, in theory, test a candidate’s coding skills and ability to solve problems with algorithms. However, today’s common technical interview is far from perfect , and a lot of algorithm challenges are too theoretical in nature to fairly assess a developer’s skills. While they are beginning to fall out of favor, some companies still ask academically advanced algorithmic questions, so it’s important to know what to expect.

You should prepare for an algorithm-style interview question by studying fundamental concepts and practicing the types of questions you might face. Some developers feel that many such interview questions can only be solved by having memorized the solution beforehand. Developers who take this approach might spend hours memorizing concepts such as greedy algorithms or Dijkstra. While this doesn’t make for the best overall experience, some developers in line for their dream apply brute force memorization to ace the interview.

Even still, developing a solid understanding of algorithmic concepts will make it easier to develop a sound answering strategy when and if you’re asked a question of this type.

Given an array of integers, find the sum of its elements. For example, if ar = [1, 2, 3] , 1 + 2 + 3 = 6. So, return 6.
Given a square matrix, calculate the absolute difference between the sums of its diagonals. For example, the square matrix ar = [1, 2, 3, 4, 5, 6 , 7, 8, 9 ], arranged in a 3×3 grid resembling a phone keypad.
Given a time in 12-hour AM/PM format, convert it to 24-hour military time. 12:00:00AM on a 12-hour clock is 00:00:00 on a 24-hour clock. 12:00:00PM on a 12-hour clock is 12:00:00 on a 24-hour clock. For example, if s = 12:01:00AM , return 00:01:00 .

Data Structures

Like algorithm questions, data structure problems are a type of interview question that have begun to fall out of favor in recent years. While data structures are a fundamental computer science concept, they’ve become associated with a needlessly complex approach to technical interviews. But some companies still ask developers to solve data structure challenges in interviews, so it’s worth being prepared.

There are many different types of data structures , including arrays, stacks, queues, linked lists, and trees, to name just a few. Each structure has its own set of properties that you’ll need to master to answer a data structure interview question.

Delete the node at a given position in a linked list and return a reference to the head node. The head is at position 0.
You are given the pointer to the head node of a linked list and an integer to add to the list. Create a new node with the given integer. Insert this node at the tail of the linked list and return the head node of the linked list formed after inserting this new node. The given head pointer may be null, meaning that the initial list is empty.
Given a pointer to the head node of a linked list, print each node’s element, one per line. If the head pointer is null (indicating the list is empty), there is nothing to print.

System Design

System design interviews challenge candidates to design a back-end system using a whiteboard or virtual diagramming tool. Candidates are asked to explain their solution and thought process as they develop their answer. To succeed in system design interviews, candidates need to both design a viable solution and explain how the components fit together.

System design questions don’t have one right answer. Instead, they give the developer the opportunity to work toward a variety of potential solutions. Hiring teams will often have interviewing guidelines to structure the conversation as well as a suggested solution.

The key to success is to focus on the big picture and not get bogged down in the details. After all — you need to plan a back-end system, not build one.

One option for grounding the details of your answer is to reference real-world experience. Sharing an example of a similar problem you’ve previously solved adds detail to the answer while also demonstrating its viability.

Design a ride-sharing service
Design a URL shortening service
Design a search engine

Strategies for Acing the Interview

Don’t forget to communicate.

A coding interview isn’t just about the code. The conversation between you and the interviewer is as important as the code itself. Throughout the entire process, you should talk out loud, explaining your approach. You could, for example, ask for more details or consider how your solution might apply to the job at hand.

Don’t put off explaining the code until after you’ve finished coding the solution. You might forget an important detail or run out of time. Describe every action you take and decision you make in real time.

Practice, Practice, Practice

Every developer knows that sufficient interview preparation is vital to a successful interview. However, the key is to practice smarter, not harder.

The goal of your practice sessions shouldn’t be to practice every possible question you could face. Instead, interviewing practice will expose you to enough questions to be familiar with the various types of questions and how to solve them. Even some of the most advanced coding questions are often just multiple computer science concepts combined together.

For example, one of HackerRank’s hardest dynamic programming problems (with only a 37.4% solve rate) is really a dynamic programing problem combined with a data structure problem. If asked a similar question in an interview, a developer who’d practiced arrays, priority queueing, and dynamic programming would be able to solve this problem despite never having seen it before.

Structure Responses With an Answering Strategy

While providing solutions to tough interview questions is certainly challenging, some developers find the hardest part of the technical interview to be the non-technical components. Explaining complex technical concepts through verbal communication is a tough skill to master in its own right.

Structuring your response with a tried-and-true answering method can make the interview go much smoother. Here are a few strategies to consider.

STAR Method

Situation, Task, Action, and Result is a great method that can be employed to answer a problem-solving or design interview question.

Situation: Identify the situation and circumstances.
Task: Define the problem or goal that needs to be addressed.
Action: What approaches and technologies will you use to solve the problem?

15 General Software Engineer Interview Questions for Hiring Software Engineers

Share this post

When hiring for a software engineering role, it’s essential to evaluate candidates on a range of skills that cover coding proficiency, problem-solving abilities, design thinking, and familiarity with best practices in software development. This set of software engineer interview questions is designed to probe these areas, ensuring that candidates have a well-rounded skill set suitable for a dynamic and challenging engineering environment.

Table of Contents

1. Can you describe your experience with object-oriented programming and explain its core principles?

Question Explanation: Object-oriented programming (OOP) is a fundamental programming paradigm used in software development. Understanding a candidate’s experience with OOP and their grasp of its core principles is crucial for evaluating their ability to design robust and maintainable code.

Expected Answer: Object-oriented programming is a paradigm based on the concept of “objects,” which can contain data and code to manipulate that data. The four core principles of OOP are:

Encapsulation : This principle involves bundling the data (attributes) and the methods (functions) that operate on the data into a single unit or class. Encapsulation helps in hiding the internal state of an object from the outside world and only exposing a controlled interface. For example:
Inheritance : This principle allows a class to inherit properties and methods from another class. It promotes code reusability and establishes a relationship between different classes. For example:
Polymorphism : This principle allows objects to be treated as instances of their parent class rather than their actual class. The most common use is method overriding, where a child class can provide a specific implementation of a method that is already defined in its parent class. For example:
Abstraction : This principle involves hiding the complex implementation details and showing only the essential features of the object. It helps in reducing complexity and allows focusing on interactions at a high level. For example:

Evaluating Responses: Candidates should demonstrate a clear understanding of each OOP principle and provide examples that showcase their practical application. Look for answers that reflect their experience in designing and implementing object-oriented solutions, as well as their ability to explain concepts clearly.

2. How do you approach debugging and resolving a critical issue in a production environment?

Question Explanation: Debugging is an essential skill for software engineers. This question assesses the candidate’s problem-solving abilities, their systematic approach to identifying and resolving issues, and their ability to handle high-pressure situations.

Expected Answer: When faced with a critical issue in a production environment, I follow a structured approach to debugging and resolution:

Identify and Reproduce the Issue : The first step is to understand the problem by gathering as much information as possible. This may involve checking logs, monitoring system performance, and communicating with users experiencing the issue. Reproducing the problem in a controlled environment is crucial for effective debugging.
Isolate the Cause : Once the issue is reproducible, I start isolating the root cause. This involves checking recent changes, examining code paths, and using debugging tools to trace the execution flow. I may use breakpoints, log statements, and other techniques to narrow down the problem area.
Implement and Test a Fix : After identifying the cause, I develop a solution and test it thoroughly in a staging environment. It’s important to ensure that the fix resolves the issue without introducing new problems. I also consider edge cases and potential impacts on other parts of the system.
Deploy and Monitor : Once the fix is tested and reviewed, I deploy it to the production environment, usually during a maintenance window to minimize disruption. Post-deployment, I closely monitor the system to ensure the issue is resolved and the system is stable.
Review and Document : After resolving the issue, I conduct a post-mortem to understand what went wrong and how it can be prevented in the future. This involves documenting the problem, the solution, and any lessons learned. I also update any relevant documentation and processes to improve our response to similar issues in the future.

Evaluating Responses: Look for a structured approach to problem-solving, an understanding of debugging tools and techniques, and an ability to handle pressure. Candidates should demonstrate a balance between technical skills and practical experience in resolving production issues. Communication and documentation skills are also important, as they reflect the candidate’s ability to work effectively in a team.

3. Explain the differences between a process and a thread. How do you manage concurrency in your applications?

Question Explanation: Understanding the distinction between processes and threads is fundamental to managing concurrency in software development. This software engineer interview question evaluates the candidate’s knowledge of operating system concepts and their ability to design and implement concurrent applications.

Expected Answer: A process is an independent execution unit that has its own memory space, while a thread is a smaller execution unit that shares the memory space of its parent process. Here are the key differences:

Isolation : Processes are isolated from each other, meaning they have their own memory and resources. Threads, on the other hand, share the same memory and resources within a process, allowing for more efficient communication but increasing the risk of synchronization issues.
Overhead : Creating and managing processes involves more overhead than threads because processes require separate memory and resource allocation. Threads are lighter and more efficient because they share the same resources.
Communication : Inter-process communication (IPC) is more complex and slower compared to inter-thread communication. Threads can easily communicate with each other by accessing shared variables, while processes need mechanisms like pipes, sockets, or shared memory.

To manage concurrency in applications, I use several techniques and tools:

Threading : For tasks that can run concurrently within the same application, I use threading. In Python, for example, I might use the threading module:
Multiprocessing : For CPU-bound tasks that benefit from parallel execution, I use multiprocessing to take advantage of multiple CPU cores. In Python, this can be done using the multiprocessing module:
Asynchronous Programming : For I/O-bound tasks, such as network or file operations, I use asynchronous programming to improve performance and responsiveness. In Python, this can be achieved using the asyncio module:

Evaluating Responses: Candidates should clearly explain the differences between processes and threads, including their advantages and disadvantages. Look for practical examples and an understanding of when to use each approach. Knowledge of specific concurrency tools and techniques in the candidate’s preferred programming language is also important.

4. Describe a time when you had to refactor a large piece of code. What approach did you take, and what were the results?

Question Explanation: Refactoring is a critical skill for maintaining and improving code quality. This software engineer interview question assesses the candidate’s ability to systematically improve existing code, their understanding of best practices, and their impact on the project.

Expected Answer: Refactoring a large piece of code requires a careful and methodical approach to avoid introducing new issues while improving the existing codebase. Here is an example from my experience:

I was working on a legacy application that had become difficult to maintain due to its monolithic structure and lack of modularization. The code was tightly coupled, making it hard to implement new features or fix bugs without affecting other parts of the system.

Initial Assessment : I started by conducting a thorough assessment of the codebase. This involved identifying the main pain points, such as duplicated code, large classes, and functions with multiple responsibilities. I also reviewed any existing documentation and spoke with team members to understand the most critical areas that needed improvement.
Planning and Prioritization : Based on the assessment, I created a refactoring plan that prioritized the most critical and impactful areas. The plan included breaking down the monolithic code into smaller, more manageable modules, improving code readability, and enhancing test coverage. I also ensured that we had a comprehensive suite of automated tests to catch any regressions.
Incremental Refactoring : I approached the refactoring incrementally, focusing on one module or functionality at a time. This allowed me to make gradual improvements without disrupting the entire codebase. For example, I refactored a large class by applying the Single Responsibility Principle, breaking it into smaller classes, each with a specific responsibility. I also replaced duplicated code with reusable functions and applied design patterns where appropriate.
Testing and Validation : After each refactoring step, I ran the automated tests to ensure that the changes did not introduce any new issues. I also performed manual testing for critical functionalities and sought feedback from team members to validate the improvements.
Documentation and Review : Once the refactoring was complete, I updated the documentation to reflect the changes and conducted code reviews with the team to ensure that the new structure was well-understood and maintained best practices.

Results : The refactoring effort significantly improved the maintainability and scalability of the application. The codebase became more modular, making it easier to implement new features and fix bugs. The improved structure also facilitated better collaboration within the team, as developers could work on different modules independently. Overall, the refactoring led to a more robust and flexible system, reducing technical debt and enhancing the application’s long-term viability.

Evaluating Responses: Look for a structured and methodical approach to refactoring, including assessment, planning, incremental changes, testing, and documentation. The candidate should demonstrate an understanding of best practices and the ability to improve code quality systematically. Emphasize the impact of their refactoring efforts on the project and team collaboration.

5. How do you ensure the scalability and performance of an application? Can you provide an example from your past work?

Question Explanation: Scalability and performance are critical for applications that need to handle growing amounts of work or data. This question assesses the candidate’s understanding of strategies and best practices to ensure an application can scale efficiently and perform optimally.

Expected Answer: Ensuring scalability and performance involves several strategies and techniques. Here’s an example from my past work:

Profiling and Monitoring : The first step is to profile the application to identify performance bottlenecks. Tools like New Relic, Datadog, or built-in profilers in development environments can help. Monitoring helps track performance metrics and resource usage in real-time.
Optimizing Code : Writing efficient code is crucial. This involves choosing appropriate algorithms and data structures, minimizing unnecessary computations, and optimizing database queries. For instance, using indexing in databases to speed up query performance.
Caching : Implementing caching mechanisms can drastically improve performance. Caching can be done at multiple levels, including database query caching (e.g., using Redis or Memcached), application-level caching, and content delivery networks (CDNs) for static assets.
Load Balancing : Distributing the load across multiple servers helps handle increased traffic and provides redundancy. Load balancers, like Nginx, HAProxy, or cloud-based solutions from AWS or Azure, can distribute incoming requests efficiently.
Horizontal and Vertical Scaling : Horizontal scaling involves adding more machines to handle the load, while vertical scaling involves adding more resources (CPU, RAM) to the existing machines. Depending on the architecture, one or both approaches can be applied.
Database Sharding : For databases that handle large volumes of data, sharding can be used to split the data across multiple databases. This helps in managing the load and improving performance.

Example : In a past project, we had a web application that started experiencing performance issues as user traffic increased. Here’s how we tackled it:

Identified Bottlenecks : Using New Relic, we identified that our database queries were taking a long time to execute and that certain parts of our code were inefficient.
Optimized Database Queries : We added indexes to the most frequently queried columns and optimized complex joins. This reduced the query execution time significantly.
Implemented Caching : We implemented Redis caching for frequently accessed data, reducing the load on our database.
Load Balancing : We set up an AWS Elastic Load Balancer to distribute incoming traffic across multiple EC2 instances, ensuring that no single server was overwhelmed.
Scalability : We adopted horizontal scaling by adding more instances as the traffic grew and used auto-scaling groups to handle traffic spikes dynamically.

Evaluating Responses: Candidates should demonstrate a comprehensive understanding of various techniques for improving scalability and performance. Look for practical examples and a clear explanation of the steps taken. Assess their ability to identify and resolve bottlenecks, implement efficient code, and use tools and techniques effectively.

6. What are design patterns, and which ones have you used in your projects? Provide specific examples.

Question Explanation: Design patterns are standard solutions to common problems in software design. This software engineer interview question evaluates the candidate’s familiarity with design patterns, their practical application, and their ability to choose the appropriate pattern for a given scenario.

Expected Answer: Design patterns are typical solutions to recurring problems in software design. They provide a template for how to solve a problem in various contexts. Here are a few design patterns I’ve used in my projects:

Singleton Pattern : This pattern ensures that a class has only one instance and provides a global point of access to it. I used the Singleton pattern to manage a database connection pool in a Java application, ensuring that only one instance of the connection pool exists and is shared across the application.
Observer Pattern : This pattern defines a one-to-many dependency between objects, so when one object changes state, all its dependents are notified. I used the Observer pattern in a notification system where multiple services needed to be updated when a user’s status changed.
Factory Pattern : This pattern provides an interface for creating objects in a super class but allows subclasses to alter the type of objects that will be created. I used the Factory pattern to create different types of users (Admin, Guest, Member) in a web application.

Evaluating Responses: Look for a clear understanding of design patterns and their practical application. The candidate should provide specific examples from their experience and explain why they chose a particular pattern. Assess their ability to describe the benefits and potential drawbacks of using design patterns in different scenarios.

7. Discuss the importance of unit testing and test-driven development (TDD). How have you implemented these practices in your work?

Question Explanation: Unit testing and test-driven development (TDD) are critical for ensuring code quality and reliability. This question evaluates the candidate’s understanding of these practices, their benefits, and their practical implementation in software development.

Expected Answer: Unit testing involves testing individual components of a software application to ensure they work as expected. Test-driven development (TDD) is a software development approach where tests are written before the code itself. Here’s why these practices are important and how I have implemented them:

Importance : Unit tests help catch bugs early in the development process, ensuring that each component works correctly in isolation. They make the codebase more maintainable and refactorable, as developers can modify code with confidence that existing functionality remains unaffected.
Implementation : In my previous projects, I used unit testing frameworks like JUnit for Java, PyTest for Python, and Jest for JavaScript. I wrote unit tests for critical functions and classes, covering both typical and edge cases.
Importance : TDD ensures that the code is tested from the start, leading to better-designed, more reliable, and maintainable code. It encourages developers to think about the requirements and design before writing the implementation.
Implementation : When following TDD, I start by writing a failing test that defines a desired improvement or new function. Then, I write the minimal code necessary to pass the test. Finally, I refactor the code while ensuring that all tests still pass.

Evaluating Responses: Candidates should demonstrate a clear understanding of the importance of unit testing and TDD, including their benefits for code quality and maintainability. Look for practical examples of how they have implemented these practices in their work. Assess their ability to write meaningful tests and follow the TDD process effectively.

8. Can you explain the concept of RESTful APIs and how you have utilized them in your projects?

Question Explanation: RESTful APIs are a common method for enabling communication between different software systems. This question evaluates the candidate’s understanding of REST principles and their practical experience in designing and consuming RESTful APIs.

Expected Answer: REST (Representational State Transfer) is an architectural style for designing networked applications. RESTful APIs use HTTP requests to perform CRUD operations (Create, Read, Update, Delete) on resources. The key principles of REST include:

Statelessness : Each request from a client to a server must contain all the information needed to understand and process the request. The server does not store any state about the client session on the server side.
Client-Server Architecture : The client and server are separate entities. The client is responsible for the user interface, and the server handles the backend processing. This separation allows for independent development and scaling.
Uniform Interface : RESTful APIs use standard HTTP methods (GET, POST, PUT, DELETE) and rely on a consistent set of URIs to access resources. This simplifies the API design and makes it easy to understand and use.
Resource-Based : Everything in a RESTful API is considered a resource, identified by URIs. Resources can be represented in various formats, typically JSON or XML.

Utilization in Projects : In a previous project, I developed a RESTful API for an e-commerce platform. The API allowed clients to manage products, orders, and customers. Here’s an example of how I designed and implemented it:

GET /products: Retrieve a list of products
POST /products: Create a new product
GET /products/{id}: Retrieve a specific product by ID
PUT /products/{id}: Update a specific product by ID
DELETE /products/{id}: Delete a specific product by ID
Implementing the API : Using a framework like Flask for Python, I implemented the endpoints. For example:
Documentation : I documented the API using tools like Swagger or Postman to provide clear instructions on how to use the endpoints, including request and response formats, status codes, and examples.

Evaluating Responses: Look for a solid understanding of REST principles and practical experience in designing and implementing RESTful APIs. Candidates should be able to explain the rationale behind their design decisions and provide examples of how they have used RESTful APIs in their projects. Assess their ability to design clean, consistent, and well-documented APIs.

9. Describe your experience with version control systems, particularly Git. How do you manage branches and handle conflicts?

Question Explanation: Version control systems are essential for collaborative software development. This question assesses the candidate’s familiarity with version control, specifically Git, and their ability to manage branches and resolve conflicts.

Expected Answer: Version control systems like Git help manage changes to source code over time. Git provides powerful branching and merging capabilities, making it ideal for collaborative development. Here’s how I manage branches and handle conflicts:

Feature Branches : Each new feature is developed in its own branch, typically created from the main or develop branch. This isolates feature development and allows multiple features to be developed simultaneously without interference.
Release Branches : Before a release, a release branch is created from develop . This branch is used for final testing and bug fixing. Once the release is ready, the release branch is merged into main and develop .
Hotfix Branches : For urgent bug fixes in the production environment, a hotfix branch is created from main . After the fix, the hotfix branch is merged back into both main and develop .
Managing Branches :

Creating a Branch : To start working on a new feature or bug fix, I create a new branch:

Switching Branches : To switch between branches, I use:

Merging Branches : After completing work on a branch, I merge it back into the base branch (e.g., develop ):

Handling Conflicts :

Identifying Conflicts : Conflicts occur when changes from different branches overlap. Git highlights conflicting files during a merge attempt.

Resolving Conflicts : I open the conflicting files and manually resolve conflicts by selecting the appropriate changes. After resolving conflicts, I add the resolved files and continue the merge.

Using Tools : For complex conflicts, I use merge tools like KDiff3 or VSCode ‘s built-in merge tool to visualize differences and resolve conflicts more easily.

Example : In a previous project, we used Git for version control with a branching strategy similar to Git Flow. This helped us manage multiple features, releases, and hotfixes efficiently. During a merge, we encountered conflicts in several files. We resolved these conflicts by discussing the changes with team members, using merge tools to visualize differences, and thoroughly testing the merged code to ensure stability.

Evaluating Responses : Candidates should demonstrate a clear understanding of Git, including common commands and branching strategies. Look for experience with resolving conflicts and using tools to manage branches effectively. Assess their ability to explain their approach to version control and collaboration within a team.

10. How do you stay current with new technologies and programming languages? Can you give an example of a recent technology you’ve learned and how you applied it?

Question Explanation: Staying updated with new technologies is crucial for software engineers. This software engineer interview question assesses the candidate’s commitment to continuous learning and their ability to apply new knowledge in practical scenarios.

Expected Answer: To stay current with new technologies and programming languages, I follow a multi-faceted approach:

Reading and Research : I regularly read technology blogs, articles, and research papers. Websites like Medium, Hacker News, and TechCrunch are valuable sources of information. I also follow thought leaders and industry experts on social media platforms like Twitter and LinkedIn.
Online Courses and Tutorials : I take online courses on platforms like Coursera, Udemy, and edX to learn new technologies and programming languages. Interactive tutorials on websites like Codecademy and freeCodeCamp are also helpful.
Community Engagement : Participating in developer communities, attending meetups, and joining online forums like Stack Overflow, Reddit, and GitHub help me learn from peers and stay updated with industry trends.

Example : Recently, I learned about Docker, a tool that allows for containerization of applications. Here’s how I applied it:

Learning Docker : I started with online tutorials and courses to understand the basics of Docker, including container creation, management, and orchestration. I also read the official Docker documentation and followed along with examples.
Applying Docker : I decided to containerize a web application I was working on. The application had multiple components, including a frontend, backend, and database. Using Docker, I created Dockerfiles for each component and defined a Docker Compose file to manage the multi-container application.
Benefits : Containerizing the application made it easier to manage dependencies, ensure consistency across development and production environments, and streamline the deployment process. I documented the setup process and shared it with my team, improving our overall development workflow.

Evaluating Responses : Candidates should show a proactive approach to learning and staying current with new technologies. Look for specific examples of how they have learned and applied new technologies in their projects. Assess their ability to articulate the benefits and challenges of adopting new tools and languages.

11. Explain the difference between relational and non-relational databases. When would you choose one over the other?

Question Explanation: Understanding the difference between relational and non-relational databases is fundamental for designing data storage solutions. This question assesses the candidate’s knowledge of database types and their ability to choose the appropriate database for different use cases.

Expected Answer: Relational and non-relational databases differ in their structure, use cases, and data management approaches.

Structure : Relational databases use tables to store data, with rows representing records and columns representing attributes. Tables can be linked using foreign keys, enabling complex queries and data integrity.
Schema : They have a predefined schema that enforces data types and relationships between tables.
Examples : MySQL, PostgreSQL, Oracle, SQL Server.
Use Cases : Relational databases are suitable for applications requiring complex queries, transactions, and data integrity. Examples include financial systems, enterprise applications, and content management systems.
Structure : Non-relational databases can store data in various formats, such as key-value pairs, documents, graphs, or wide-column stores. They are more flexible in terms of data structure.
Schema : They have a dynamic schema, allowing for more flexible and scalable data models.
Examples : MongoDB (document), Redis (key-value), Cassandra (wide-column), Neo4j (graph).
Use Cases : Non-relational databases are suitable for applications with large volumes of unstructured or semi-structured data, real-time analytics, and flexible data models. Examples include social networks, big data applications, and IoT systems.

Choosing Between Them :

Data Structure and Integrity : If the application requires complex relationships and data integrity, a relational database is preferred. For example, in an e-commerce platform where transactions and customer data integrity are crucial, an RDBMS like PostgreSQL would be suitable.
Scalability and Flexibility : For applications with dynamic and scalable data models, a non-relational database is preferred. For example, in a real-time analytics system for monitoring IoT devices, a NoSQL database like MongoDB or Cassandra would be more appropriate due to their horizontal scalability and flexible schemas.
Performance : For high read/write throughput and low latency, non-relational databases are often better. Redis, a key-value store, is ideal for caching and session management due to its in-memory data storage.

Example : In a project where we developed a social media platform, we used both relational and non-relational databases. User authentication and profile data were stored in PostgreSQL due to the need for data integrity and complex queries. For storing user-generated content like posts and comments, we used MongoDB because of its flexible schema and scalability. This hybrid approach allowed us to leverage the strengths of both database types.

Evaluating Responses : Candidates should demonstrate a clear understanding of the differences between relational and non-relational databases, including their structures, use cases, and benefits. Look for practical examples of when they have used each type of database and their rationale for choosing one over the other. Assess their ability to explain how different databases can be integrated within a single application to meet specific requirements.

12. What is your experience with cloud platforms such as AWS, Azure, or Google Cloud? Can you describe a project where you utilized cloud services?

Question Explanation: Cloud platforms provide a wide range of services for building, deploying, and managing applications. This software engineer interview question assesses the candidate’s experience with cloud platforms and their ability to leverage cloud services in real-world projects.

Expected Answer: I have extensive experience with cloud platforms, including AWS, Azure, and Google Cloud. Each platform offers a variety of services for computing, storage, databases, networking, and more. Here’s an overview of my experience and a specific project where I utilized cloud services:

Services Used : EC2 for compute, S3 for storage, RDS for relational databases, Lambda for serverless computing, and CloudFormation for infrastructure as code.
Example : In a recent project, I used AWS to build a scalable web application. We utilized EC2 instances for the application servers, S3 for storing user-uploaded files, and RDS (PostgreSQL) for the database. AWS Lambda was used for processing background tasks, and CloudFormation was used to define and manage the infrastructure.
Services Used : Azure App Services for web hosting, Azure SQL Database for relational data, Azure Functions for serverless computing, and Azure DevOps for CI/CD pipelines.
Example : In a previous job, we migrated an on-premises application to Azure. We used Azure App Services to host the web application, Azure SQL Database for data storage, and Azure Functions to handle event-driven processing. Azure DevOps was used to automate the deployment pipeline, ensuring quick and reliable releases.
Services Used : Compute Engine for virtual machines, Cloud Storage for object storage, Firestore for NoSQL databases, and Cloud Run for deploying containerized applications.
Example : In a side project, I built a microservices-based application using Google Cloud. We used Compute Engine to run the services, Cloud Storage to store media files, and Firestore as the database. Cloud Run was used to deploy and manage the containerized services, providing a scalable and efficient solution.

Project Example : In a recent project, we developed a serverless data processing pipeline on AWS. The goal was to process and analyze large volumes of data in real-time. Here’s how we utilized AWS services:

Data Ingestion : We used AWS Kinesis Data Streams to ingest data from various sources. Kinesis allowed us to process data streams in real-time with low latency.
Data Processing : AWS Lambda functions were triggered by Kinesis events to process the incoming data. Lambda’s serverless architecture enabled us to scale the processing automatically based on the volume of data.
Data Storage : Processed data was stored in Amazon S3 for long-term storage and Amazon Redshift for analytics. S3 provided a cost-effective and durable storage solution, while Redshift enabled us to run complex queries and generate insights from the data.
Infrastructure Management : We used AWS CloudFormation to define and deploy the entire infrastructure as code. This approach ensured consistency and made it easy to replicate the environment in different regions.

Evaluating Responses : Candidates should demonstrate familiarity with major cloud platforms and their services. Look for specific examples of how they have used cloud services in projects, focusing on the architecture, tools, and outcomes. Assess their ability to explain the benefits of using cloud platforms, such as scalability, reliability, and cost-efficiency.

13. How do you handle security concerns in your software development process? Provide specific measures you take to ensure security.

Question Explanation: Security is a critical aspect of software development. This question evaluates the candidate’s understanding of security best practices and their ability to implement measures to protect applications and data.

Expected Answer: Handling security concerns in software development involves adopting best practices and implementing specific measures throughout the development lifecycle. Here are the steps I take to ensure security:

Input Validation : Validate and sanitize all user inputs to prevent injection attacks, such as SQL injection and cross-site scripting (XSS).
Output Encoding : Encode data before rendering it to the user to prevent XSS attacks.
Authentication and Authorization : Implement strong authentication mechanisms, such as multi-factor authentication (MFA), and enforce least privilege access control.
Data Encryption : Use encryption to protect sensitive data at rest and in transit. For example, use HTTPS to encrypt data transmitted over the network and AES for encrypting data stored in databases.
Password Storage : Store passwords using strong hashing algorithms, such as bcrypt or Argon2, with a unique salt for each password.
Vulnerability Scanning : Regularly scan third-party libraries and dependencies for known vulnerabilities using tools like Snyk or OWASP Dependency-Check.
Updating Dependencies : Keep dependencies up-to-date and apply security patches promptly.
Static Code Analysis : Use static analysis tools, such as SonarQube or ESLint, to identify potential security issues in the code.
Penetration Testing : Conduct regular penetration testing to identify and address security vulnerabilities from an attacker’s perspective.
Automated Security Tests : Integrate security tests into the CI/CD pipeline to catch security issues early in the development process.
Logging and Monitoring : Implement comprehensive logging and monitoring to detect and respond to security incidents in real-time. Use tools like ELK Stack (Elasticsearch, Logstash, Kibana) or Splunk.
Incident Response Plan : Develop and maintain an incident response plan to handle security breaches effectively and minimize damage.

Example : In a recent project, I was responsible for developing a web application that handled sensitive user data. Here are the specific security measures I implemented:

Input Validation : I used a validation library to ensure all user inputs were properly validated and sanitized.
Encryption : I enforced HTTPS using SSL/TLS certificates and encrypted sensitive data stored in the database with AES-256 encryption.

Basic-level IT Support Interview Questions

Here are some of the basic-level Support Interview Questions and Answers:

1) Define Hard-disk partitions.

Hard-disk partitions divide a physical hard disk drive into distinct sections, each treated as an independent unit by the Operating System. This arrangement allows for improved data management, enabling distinct storage spaces for various file types or Operating Systems on a single disk.

Partitioning enhances data organisation and facilitates efficient backups and system recovery. It boosts overall system performance by segregating data into manageable units, thereby optimising access times and simplifying maintenance tasks.

2) What is the difference between RAM and ROM?

Random Access Memory (RAM) and Read-Only Memory (ROM) are two kinds of computer memory that perform different functions. RAM is a type of volatile memory that stores information as well as instructions for quick access by the Central Processing Unit (CPU). It is used to start applications and multitask.

In contrast, ROM is a non-volatile memory that keeps data forever and cannot be updated. It contains the software or basic instructions needed to start the computer and perform important tasks like Basic Input/Output System (BIOS) operations.

3) Which desktop Operating Systems are you familiar with?

This question aims to gauge the candidate's familiarity with various desktop Operating Systems.

Here's a sample answer:

“I am familiar with several desktop Operating Systems, including Microsoft Windows (such as Windows 10, Windows 8, and Windows 7), macOS (formerly OS X), and various Linux distributions (such as Ubuntu, Fedora, and CentOS). I have experience in installing, configuring, and troubleshooting these Operating Systems to ensure smooth system performance and user satisfaction.”

4) What would you check if your computer's audio is not working?

This question tests the candidate's troubleshooting skills related to audio issues.

“If the audio for my computer is not working, I would first check the volume settings to make sure that the sound is not muted or set too low. Next, I would verify that the audio device is effectively connected to the computer and powered on.

Then, I would inspect the device manager to see if there are any issues with the audio drivers. If necessary, I would update or reinstall the audio drivers. Additionally, I would check the audio playback settings to ensure that the appropriate audio device is selected as the default playback device.”

5) What are some of the ports available on a computer?

Some common ports available on a computer include:

1) Universal Serial Bus (USB) ports connect external devices, including keyboards, printers, and storage devices.

2) High-Definition Multimedia Interface (HDMI) connectors allow you to connect displays, monitors, and projectors.

3) Ethernet ports allow wired connection to the network.

4) Audio ports allow you to connect headphones, microphones, and speakers.

5) Video Graphics Array (VGA) connectors allow you to connect outdated screens or projectors.

6) Thunderbolt ports provide for high-speed data transfers and accessory connectivity.

6) List five Microsoft Office applications.

Five Microsoft Office applications include:

1) Microsoft Word - for word processing and document generation.

2) Microsoft Excel - for spreadsheet creation, Data Analysis, and calculations.

3) Microsoft PowerPoint - for creating presentations with slides, graphics, and animations.

4) Microsoft Outlook - for email management, calendar scheduling, and contact organisation.

5) Microsoft Access - for Database Management and development.

7) What is the purpose of BOOT.INI?

BOOT.INI is a critical system file employed by older Windows Operating Systems like Windows XP. It resides in the root directory of the system partition and governs the boot configuration options.

BOOT.INI specifies crucial details like the location of the Operating System files and the necessary boot parameters to initiate the system. These parameters include the boot partition, the specific version of the Operating System, and various boot options, playing a pivotal role in system startups.

8) What does USB stand for?

Universal Serial Bus (USB) is a standardised connection interface that enables mouse, keyboard, printers, external storage devices, and smartphones to be easily connected to a computer. USB ports are widely utilised due to their adaptability, ease of use, and connectivity with a wide variety of devices.

9) What is the Blue Screen of Death (BSOD)?

The Blue Screen of Death (BSOD) is an error screen that appears on a Windows computer after a serious system problem. It indicates a system crash, in which the Operating System has reached the point where it can no longer run safely. This screen provides error codes that can help diagnose the underlying issue.

10) What is BIOS?

BIOS, or Basic Input/Output System, is software installed on a motherboard chip that initialises and checks hardware components on starting. It loads the Operating System from a storage device and includes an administration interface for changing system factors.

This critical system software ensures that all system components function correctly. It allows for customisation of hardware settings to optimise performance and compatibility with various software and hardware configurations.

This question aims to test your knowledge of different iterations of a specific Operating System.

"Certainly, some of the primary versions of Windows XP that I am aware of include XP Home Edition, which is aimed at normal buyers, and XP Professional, which is designed for businesses and advanced users. There's also XP Media Centre Edition, which is specifically designed for multimedia, and XP Tablet PC Edition, which is optimised for tablet devices."

12) What made you start a career in tech support?

The purpose of this question is to understand your motivation for choosing this career path.

“I started a career in tech support because I've always had a passion for technology and problem-solving. I enjoy the dynamic nature of IT, where there is always a new problem to solve or a new piece of technology to learn. Being in tech support allows me to help others while continuously improving my technical skills.”

Intermediate-level IT Support Interview Questions

Here are some of the intermediate-level Support Interview Questions and Answers:

13) What is your style of management?

This question explores your management philosophy and approach.

"My management style is primarily collaborative and supportive. I focus on motivating my team by providing them with the resources and knowledge they need for success. I want to establish an open communication atmosphere in which team members feel comfortable expressing ideas and discussing difficulties, ensuring that everyone feels appreciated and can contribute effectively to our common goals."

14) In our industry, what are some important trends that you see?

The purpose of this question is to gauge your awareness of industry-specific trends.

“In the IT industry, I've observed several pivotal trends. Firstly, there's a significant increase in the adoption of Cloud Computing, which provides scalability and flexibility. Secondly, artificial intelligence and machine learning are increasingly integrated into applications, enhancing automation and analytical capabilities.

Additionally, due to escalating Cyber Security threats, there's a heightened focus on robust security measures. Finally, the role of Data Analytics remains crucial, continuously driving informed decision-making in businesses across various sectors.”

15) What are your reasons for leaving your previous/present job?

This question seeks to understand your motivations for seeking a new position.

“I am seeking a new position to encounter more challenging projects and opportunities for professional growth that better align with my long-term career goals. Although I have gained significant experience and developed considerably in my current role, I believe that a new environment will offer me a broader platform.

This will allow me to further contribute, innovate, and refine my skills. Finally, it will allow me to make a more significant contribution to the business by driving success and promoting innovation in accordance with its goals."

16) What do you feel is an appropriate salary for this position?

The purpose of this question is to understand your salary expectations.

Here's a sample answer:

“I would base my salary expectations on the industry standards, my professional experience, and the specific responsibilities associated with this position. Having researched similar roles within the industry and considered the scope and demands of this job, I would expect a salary. This salary should reflect both the market rate and the value I bring to the role.

Consequently, for this position, I would anticipate a salary range that aligns with these factors. This ensures that the compensation is fair and commensurate with the expectations and requirements laid out for this role.”
