Deloitte Interview Process

The Deloitte interview process typically consists of two rounds of interview that include case interviews, a group case interview, and behavioral or fit interview questions. The entire interview process can take anywhere from one week to a few months.

Given its size, Deloitte may have a different interview process depending on the country or the office that you are interviewing for. However, the most common interview process consists of two rounds of interviews following the submission of your Deloitte resume .

• First round interviews : you will have one 30 to 45-minute behavioral interview and one or two 30 to 45-minute case interviews.
• Final round interviews : you will have a 30 to 45-minute behavioral interview, a 30 to 45-minute case interview, and a one hour group case interview

There are three important distinctions between your first round Deloitte interview and your final round Deloitte interview.

One, your interviewers will likely be more senior people at Deloitte. This means that the case interviews you receive may be a bit less structured and more qualitative in nature. The case interview may feel more like a discussion where you and the interviewer are discussing your opinions and ideas on a business problem.

Two, there will be more of an emphasis on assessing your fit with the firm. The first round interview is primarily used as a screener to determine whether or not you can solve case interviews effectively and whether or not you have the potential to be a great consultant.

Final round interviews will also continue to assess this, but interviewers will also be determining whether or not you would be a great fit with the office. Are you coachable and easy to work with? Are you collaborative? These are a few of the qualities that interviewers want to see.

Three, your interviewers may read the notes that your interviewers wrote during your Deloitte first round interview. If there was a particular area of the case interview that you struggled with, interviewers may want to test you again on it to make sure that it is not a significant weakness.

What is a Deloitte Case Interview?

A Deloitte case interview, also known as a “case” for short, is a 30 to 60-minute exercise in which you and the interviewer work together to develop a recommendation or answer to a business problem.

These business problems can be anything that real companies face:

• How can Amazon increase its profitability?
• What can Apple do to increase customer retention?
• How should Tesla price its new electric vehicle?
• Where should Disney open another Disneyland theme park?

Deloitte case interviews simulate what the consulting job will be like by placing you in a hypothetical business situation. Cases simulate real business problems that consulting firms solve for their clients. Many Deloitte case interviews are based on actual projects that interviewers have worked on.

While consulting projects typically last between 3 to 9 months, case interviews condense solving the business problem into just 30 to 45 minutes.

Deloitte case interviews can cover any industry, including retail, consumer packaged goods, financial services, energy, education, healthcare, government, and technology.

They can also cover a wide range of business situations, including entering a new market, launching a new product, acquiring a company, improving profitability, and growing revenues.

Although Deloitte case interviews cover a wide range of industries and business situations, no technical or specialized knowledge is needed. Unless you are interviewing for a consulting firm that specializes in a particular industry or function, cases are designed to be solved by someone that has general business knowledge.

Nailing your Deloitte case interviews is critical to get a job at Deloitte. There is no way to get a Deloitte job offer without passing your case interviews.

What Does a Deloitte Case Interview Assess?

Deloitte case interviews assess five different qualities or characteristics: logical and structured thinking, analytical problem solving, business acumen, communication skills, and personality and cultural fit.

1. Logical and structured thinking : Consultants need to be organized and methodical in order to work efficiently.

• Can you structure complex problems in a clear, simple way?
• Can you take tremendous amounts of information and data and identify the most important points?
• Can you use logic and reason to make appropriate conclusions?

2. Analytical problem solving : Consultants work with a tremendous amount of data and information in order to develop recommendations to complex problems.

• Can you read and interpret data well?
• Can you perform math computations smoothly and accurately?
• Can you conduct the right analyses to draw the right conclusions?

3. Business acumen : A strong business instinct helps consultants make the right decisions and develop the right recommendations.

• Do you have a basic understanding of fundamental business concepts?
• Do your conclusions and recommendations make sense from a business perspective?

4. Communication skills : Consultants need strong communication skills to collaborate with teammates and clients effectively.

• Can you communicate in a clear, concise way?
• Are you articulate in what you are saying?

5. Personality and cultural fit : Consultants spend a lot of time working closely in small teams. Having a personality and attitude that fits with the team makes the whole team work better together.

• Are you coachable and easy to work with?
• Are you pleasant to be around?

All of these five qualities can be assessed in just a 30 to 60-minute Deloitte case interview. This is what makes case interviews so effective in assessing consulting candidates.

How to Solve Deloitte Case Interviews

Deloitte case interviews are candidate-led. You will be in the driver’s seat of the case interview and will be expected to ask the right questions, probe for data, and propose each next step to solve the case.

In a Deloitte case interview, you are not assessed on whether or not you have the correct answer. Instead, Deloitte uses case interviews to assess six different qualities:

• Problem solving : Can you decompose a problem into smaller, more manageable questions?
• Analytical ability : Can you draw the right insights from data and information?
• Strategic thinking : Do you have a sharp business acumen and practical business judgment?
• Logical thinking : Are you structured, organized, and rational in the way that you think?
• Creativity : Can you generate interesting or unique ideas and solutions?
• Professional demeanor : Are you calm, confident, and articulate?

Our step-by-step guide to case interviews is presented in the video below. We highly recommend watching that video in its entirety. 

On Deloitte's case interview website , they recommend taking five   steps to solve a case interview:

1. Understand the issue and ask clarifying questions

The most important part of the case interview is to make sure you understand the business issue and the objective of the case. The quickest way to fail a case interview is to answer or address the wrong business problem. 

Therefore, if either the business issue or objective of the case is unclear, make sure to ask clarifying questions.

2. Identify the underlying assumptions

Next, you’ll need to decompose the overall business problem into smaller, more manageable issues. Identify what would need to be true in order for you to recommend a particular course of action.

To do this, it will be helpful to put together a framework, which is a tool that helps you organize your ideas and thoughts into different categories. For a complete guide on how to create tailored and unique frameworks for each case, check out our article on case interview frameworks .

3. Summarize specific issues and findings

Afterwards, you’ll begin investigating different issues or areas of your framework. After investigating each one, it is important that you summarize the key takeaways or insights that you uncovered.

Connect these findings back to the overall business problem and explain how your findings impact your potential recommendation.

4. State your recommendations

Once you have gathered enough evidence and support for your recommendation, you will need to present your recommendation in a clear and concise way.

Start by giving a firm recommendation. Then, provide the three major reasons that support your recommendation. This should summarize most of the important findings from the case.

5. Outline next steps and the expected results or impact

After delivering a recommendation, you should propose potential next steps that you would take if you had more time or data. What would you need to know to further strengthen your recommendation or make you more confident in your answer?

You can also talk about the expected results or impact of your recommendation. This may also have implications on potential next steps, such as analyzing the risks or quantifying the financial benefits. 

The Different Types of Deloitte Case Interviews

There are three different types of Deloitte case interviews, one type for each of Deloitte's consulting groups:  

• Strategy & Operations : primarily focused on corporate strategy, supply-chain improvement, business model transformation, and process improvements. The work that this group does is most similar to the work that McKinsey, BCG, and Bain do
• Business Technology : primarily focused on digital strategy, delivery of information technology programs, and building tech-based solutions for clients
• Human Capital : primarily focused on organization transformation, change management, corporate learning and development, and diversity and inclusion

The type of case that you get depends on what group you are interviewing with. 

For example, If you are interviewing with the Strategy & Operations group, you’ll get a strategy or operations case . You may be asked to determine whether to enter a new market, launch a new product, or make an acquisition.

If you are interviewing with the Technology group, you’ll get a technology or IT case. You may be asked to determine whether to roll out a new IT system, how to assess different technologies, or how to best coordinate an IT transformation.

If you are interviewing with the Human Capital group, you may be asked to determine the optimal organization structure, how to better incentivize employees to perform better, or how to save payroll costs.

  Deloitte Case Interview Tips

Below are eight of Deloitte's case interview tips to help you improve your case interview performance.

Tip #1: Take notes

While the interviewer is providing you with the case background information, take notes on the most important pieces of information. Pay particularly close attention to the context, company, and case objective.

Tip #2: Make sure you understand the case question

Answering or addressing the wrong business problem is the quickest way to fail a case interview. The most important thing is understanding what the business issue is and what overall question you’ll be expected to answer at the end of the case. 

Tip #3: Ask questions

Do not be afraid to ask questions. You will not be penalized for asking questions that are important and relevant to the case. 

Great questions to ask include asking for the definition of an unfamiliar term, asking questions that clarify the objective of the issue, and asking questions to strengthen your understanding of the context or company.

Tip #4: After you develop a framework, develop an initial hypothesis

A hypothesis is an educated guess on the answer based on the data and information that you have so far. It helps guide your analysis and keeps you on the right track.

After developing a framework, try to develop a hypothesis to help you decide what area of your framework you should explore first.

Tip #5: Take time to structure your thoughts

When asked a question in a case interview, don’t always start answering immediately. Instead, take the time to process the question and develop an organized and structured way to answer it. It is acceptable to ask the interview for a brief moment to collect your thoughts.

Your answer will likely be much stronger if you give yourself time to think. 

Tip #6: Present a clear, logical story for your recommendation

Remember that consultants need to convince clients to follow their proposed recommendations. Being articulate and persuasive are necessary skills for management consultants .

When you deliver your recommendation, try to make it a coherent story. This will make your recommendation easier to follow and more compelling.

Tip #7: Walk the interviewer through your thinking and explain assumptions

You do not get any points for the ideas and thinking that you do not communicate. Therefore, you should make every effort to talk through your thoughts out loud.

Walk the interviewer through what you are thinking. Explain why you have made particular decisions. State your assumptions. This makes it easier for the interviewer to provide feedback or hints to help you out.

Tip #8: Engage the interviewer in a business conversation

Remember that a case interview is a collaborative exercise. You should not be dismissing the feedback and suggestions that the interviewer provides you. They may be trying to help steer the case in the right direction or provide you with hints when you get stuck.

Treat the interviewer as your teammate and turn the case interview into a business conversation.

How to Prepare for Deloitte Case Interviews

There are seven steps to preparing for Deloitte case interviews.

1. Understand what a case interview is

The first step in preparing for Deloitte case interviews is to understand exactly what case interviews are.

When you are familiar with what case interviews are, it is important to know what a great Deloitte case interview performance looks like.

Knowing what a great Deloitte case interview performance looks like will facilitate how quickly you learn case interview strategies in the next step.

Before continuing onto the next step, you should be familiar with:

• The overall objective of a case interview
• The structure and flow of a case interview
• The types of questions you could get asked
• What a great case interview performance looks like

2. Learn the right strategies

Now that you have sufficient background knowledge, the next step in preparing for Deloitte case interviews is to learn the right strategies to build good case interview habits.

It is much more effective to learn the right case strategies the first time than to learn poor strategies and try to correct them later.

The quickest, most efficient way to learn these strategies is to go through our Comprehensive Case Interview Course .

If you prefer reading case interview prep books instead, the three I recommend are:

• The Ultimate Case Interview Workbook
• Case Interview Secrets

Hacking the Case Interview provides strategies on exactly what to do and what to say in every step of the case interview. It is a concise and straight to the point guide. I recommend this book as the first book to read for beginners.

Case Interview Secrets teaches core concepts such as the issue tree , drill-down analysis, and a hypothesis driven approach. It illustrates these concepts through stories and anecdotes. If you have read Hacking the Case Interview, I recommend also reading this book to get perspectives from a second author. Check out our full review of Case Interview Secrets .

Case in Point provides a ton of specific and complex frameworks. However, you likely won’t be using many of these in an actual case interview because many of them are overly complex and specific. If you have time, it may be useful to skim through this book. Check out our full review of Case in Point .

At the bare minimum, read either the first or second book. If you have the time, read the first two books so that you can get strategies from two different authors.

Make sure to spend sufficient time learning the right strategies before starting to practice cases. It is ineffective to practice cases if you have no idea what strategies to practice and refine.

Before moving onto the next step, you should at least have strategies for the following parts of a case interview:

• Developing unique and tailored frameworks
• Solving quantitative problems
• Answering qualitative questions
• Delivering a recommendation

3. Practice 3-5 cases by yourself

Once you have learned the right strategies, the next step in Deloitte case interview prep is to practice.

When practicing case interviews, it is usually better to practice with a case interview partner than to practice by yourself . Casing with a partner better simulates the real case interview experience.

However, when you are just starting to practice, I recommend doing the first 3 – 5 cases by yourself.

There are three reasons for this:

• You can get the hang of the case interview structure and format much more quickly working by yourself rather than having to wait to schedule a time with a partner
• There are many aspects of case interviews that you can practice without a partner, such as structuring a framework and solving quantitative problems. You can get much more practice working through these parts by yourself
• You may have difficulty finding a case interview partner if you are a complete beginner. Without having done any cases, you likely won’t know how to properly give a case or provide good feedback

4. Practice 5-10 cases with a partner

The next step in preparing for Deloitte case interviews is to case with a partner.

Casing with a partner is the best way to simulate a real case interview. There are many aspects of case interviews that you won’t be able to improve on unless you practice live with a partner.

When practicing cases with a partner, ensure you are spending enough time after cases to deliver feedback.

For a case that takes around 30 – 40 minutes, spend at least 15 – 20 minutes for feedback. Much of your learning and improvement will come from these feedback sessions.

Do not move onto the next step until you have done at least 5 – 10 cases and are beginning to feel comfortable with case interviews.

5. Practice with a former or current consultant

At this point, I highly recommend asking former or current consultants to give you a practice case. This will significantly help you prepare for case interviews.

Doing a mock case with a former or current consultant is highly advantageous because they know exactly how to run cases and give feedback. You’ll receive incredibly helpful feedback that your previous case partners likely missed.

If you feel that you are plateauing with your case partner, that is a sign you should do a mock case interview with a former or current consultant.

You can find former or current consultants among:

• People you met during the consulting recruiting process
• Your broader LinkedIn network

I would not ask a consultant that is involved with the consulting recruiting process for a case too prematurely. Although these practice cases are not evaluative, some firms will actually make note of how well you perform during the practice case.

At this point, you will have accumulated a long list of improvement areas from all of the different people you have cased with.

6. Work on your improvement areas

In this step of preparing for Deloitte case interviews, you will work on strengthening and fine-tuning your improvement areas. Examples of common improvement areas include:

• Creating a more complete and mutually exclusive framework
• Performing math calculations quicker or more smoothly
• Providing more structure to your qualitative answers
• Leading the case more proactively
• Delivering a more succinct recommendation

Try to focus on improving one thing at a time. This is much more effective than trying to improve everything at once.

For some areas, such as math, it will be better to work independently. For other areas, such as learning to proactively lead the case, it will be better to work with a case partner.

If you are looking for more cases, look at the resources listed in step four. If you are looking for specific drills or practice problems for a particular part of a case interview, check out The Ultimate Case Interview Workbook .

Do not move onto the next step until you have finished working on all of your improvement areas.

7. Stay sharp

If you have progressed this far, congratulations! You have almost finished preparing for Deloitte case interviews.

Once you feel that you have no more improvement areas to work on, the key is to not burn yourself out by doing too many unnecessary cases.

While each case that you do makes you slightly better, there is a point when doing too many cases can create case fatigue right before your interview. Case fatigue can negatively impact your interview performance.

On the other hand, you also don’t want to go weeks without having done a case. You may end up forgetting strategies or become rusty and slow.

Once you have achieved case mastery, I recommend doing no more than 2 cases per week in the weeks leading up to your interview. This ensures that you remain sharp for case interviews, but don’t have case fatigue.

How to Solve the Deloitte Group Case Interview

Deloitte is one of the few consulting firms that uses group case interviews in their final round of interviews. They conduct group case interviews because Deloitte’s work culture has a huge emphasis on teamwork and culture fit.

Here’s what to expect:

• You’ll be put into a group with 3 to 5 other candidates
• The interviewer will hand out case materials
• You’ll be given 10 minutes to review the case materials and prepare
• The group will have a discussion for 20 minutes
• During this discussion, interviewers will be observing candidates and will not interfere
• Afterwards, the interviewer will ask the group specific questions for another 20 minutes

Group case interviews can be challenging to prepare for because it is difficult to replicate the exact conditions to practice them. However, if you prepare for case interviews well, you will be in a great position to succeed in group case interviews.

Your goal in a group case interview is to add value to the group. There are six different ways that you can add value:

• Lead or facilitate the discussion : You can propose what topics to discuss, the order they should be discussed in, and how much time should be allocated towards each topic. If the group gets off track, you can bring the group’s focus back together.
• Expand upon other people’s ideas : If a group member suggests a great idea or raises a good point, build upon it and make it even better.
• Synthesize information : You can summarize information that other people have said and reconcile different viewpoints and ideas together.
• Keep track of time : You can volunteer to keep track of time and make sure that the group is on track.
• Play devil’s advocate : You can help your group develop strong ideas by testing the team’s thinking by considering potential risks or downsides of their ideas.
• Take notes:  You can keep track of what other people are saying so that you can recall what has been discussed if any group members have questions.

Follow these five tips to shine during your Deloitte group case interview.

Tip #1: Treat your group members as teammates, not competition

The group case interview is not an exercise in which you are competing with others. Interviewers are trying to assess whether you would be a great teammate. Multiple people or even all people in your group can receive job offers.

Therefore, focus on adding value to the group rather than making yourself look better than your teammates.

Tip #2: Don’t speak too much, but don’t speak too little

If you speak too much, this may be seen as being too aggressive or controlling. If you speak too little, you may come off as shy or timid.

If you were to rank all of the members in your group by how much each person spoke, you would want to be roughly in the middle. This would be the perfect balance of speaking and listening.

Tip #3: Don’t interrupt or talk over your group members

Interrupting others when they are speaking is rude and disrespectful. You do not want to be inconsiderate or a jerk. Be nice and respectful to your group members.

Tip #4: Involve other people

If you observe that someone has not spoken much, ask them for their thoughts or opinions. If you notice that someone has been cut off when they were speaking, ask them to finish their thoughts after the person interrupting them has finished what they have to say.

These are easy ways to show interviewers that you are a considerate and helpful teammate.

Tip #5: Speak only if you are adding value to the group

Just because you are speaking a lot during the group case interview does not mean that you are doing well. Interviewers are not assessing you purely on the quantity of what you say. They care more about the quality.

Great teammates know when to speak and when to listen. Therefore, you should speak only if you are adding some kind of value to the group. Interviewers can tell when people are speaking for the sake of getting air time.

Deloitte Behavioral and Fit Interview Questions

In addition to case interviews, you will likely be asked a few behavioral or fit interview questions. There are ten questions that are most commonly asked.

1.  Why Deloitte?

How to answer: Provide your three biggest reasons why you’re interested in working at Deloitte. You could mention that you loved the people that you have met from Deloitte so far. You can talk about Deloitte’s massive global presence, their expertise in nearly any industry or function, or their professional development opportunities.

2. Why consulting?

How to answer: Again, provide three reasons for why you’re interested in consulting. You could mention the fast career progression opportunities, the learning opportunities to develop soft and hard skills, or the level of impact that you can make right away in consulting.

3. Walk me through your resume.

How to answer: Provide a concise summary of your work experience, starting with the most recent. Focus on emphasizing your most impressive and unique accomplishments. At the end, tie your experiences to why you are interested in consulting and why you would be a great fit for Deloitte.

4. What accomplishment are you most proud of? 

How to answer: Choose your most impressive, unique, or memorable accomplishment. Structure your answer by providing information on the situation, the task, the actions you took, and the results of your work. Explain why the accomplishment is so meaningful to you and what qualities that reveals about you as a person.

5. Tell me about something that is not on your resume.

How to answer: This is a great opportunity to highlight an accomplishment that is not related to your professional work experience. Perhaps there is a non-profit that you volunteer at, a side project or business that you work on, or a hobby that you have won awards or recognition for. Select an accomplishment that is impressive and interesting.

6. Tell me about a time when you had to lead a team.

How to answer: If possible, choose a time when you directly managed a person or a team. For this question and the following similar questions, make sure that you structure your answer. Provide information on the situation, the task, the actions you took, and the results of your work. This is known as the STAR method and is the most common way of answering behavioral or fit interview questions. 

7. Describe a time when you faced conflict or disagreement.

How to answer: When answering this question, focus on emphasizing the steps you took to resolve the conflict or disagreement. Speak about the interpersonal skills you had to use in order to mediate the situation. Interviewers want to know that you can handle conflict in a constructive way.

8. Give an example of a time when you successfully persuaded someone.

How to answer: Choose a time when you were able to change someone’s mind who originally disagreed with you. Focus on emphasizing the steps that you took to persuade that person and what impact this had on the organization. Interviewers want to know that you are a great communicator and have strong people skills.

9. Tell me about a time when you failed.

How to answer: Choose a time when you failed to meet a deadline or did not meet expectations. You do not want to pick a failure that is too big or embarrassing. Focus on emphasizing what you learned from the experience and how you used that experience to deliver even better results in the next opportunity that you got. Interviewers want to see that you strive to learn from your past failures and are always working to get better.

10. Are there any questions that you have for me?

How to answer: This is a fantastic opportunity to get to know the interviewer on a more personal level. Ask them questions about their experience in consulting. Ask what their favorite case was or what they are looking to do next in their career. The more you can get the interviewer talking about themself, the more likely they will be to have a positive impression of you. People love talking about themselves, so make sure to listen attentively and ask follow-up questions.

If you do decide to eventually use a case interview coach, consider using our case coaching service .

There is a wide range of quality among coaches, so ensure that you are working with someone that is invested in your development and success. If possible, ask for reviews from previous candidates that your coach has worked with.

The Deloitte Case Interview: What to Expect

Deloitte Group Case Interview

Have an interview with Deloitte Consulting coming up? If so, you’ll want to know what to expect and how to prepare.

We’ve got you covered, including our 6 tips on how to ace your Deloitte case interview!

In this article, we’ll discuss:

• What the Deloitte Consulting case interview process looks like,
• The Deloitte case interview: what to expect,
• Sample Deloitte case interviews,
• Our 6 tips on acing the Deloitte case interview,
• The Deloitte group case interview, and
• The Deloitte behavioral interview question.

Let’s get started!

What the Deloitte Consulting Interview Process Looks Like

Initial application.

The Deloitte Consulting interview process has 4 steps:

• Application
• Online assessment
• First round interviews
• Final round interviews

If you’re a student, make sure you know if you need to apply directly to Deloitte Consulting or through your career center.

As part of your application, you’ll need to submit your resume and, for campus hires, your academic transcript. Research which office you want to apply for as you’ll need to state that at this stage.

Deloitte Online Assessment

The second stage of the Deloitte Consulting recruitment process is an online assessment. This assessment tests numerical reasoning and your situational judgment.

Information from recent candidates suggests there are 35 questions split over 5 distinct sections. We’ve got all you need to know about this part of the process in our article, Deloitte Online Assessment: What It Is & How To Pass .

Deloitte Consulting First Round Interviews

If you’re selected for a Deloitte interview you’ll be contacted via your campus career center or direct by the Deloitte recruiting team.

For campus hires, first-round interviews often take place on campus and include one or 2 interviews. These interviews include both case and behavioral interview questions. We’ve heard the cases include market-sizing as well as the non-profit sector.

The same types of interviews are used for non-campus hires.

Deloitte Consulting Final Round Interviews

Final round interviews may take place virtually, on campus, or in a Deloitte office. While the exact format depends on the position you’re applying to, expect both behavioral and case interviews at this stage. Candidates may also have a group case interview.

Deloitte will let you know the outcome of your application within a week of the final round interview.

Case interviews can feel daunting for many candidates. In this section, we’ll cover what type of cases Deloitte uses and how to approach them so you can feel confident in tackling them.

What Exactly Is a Case Interview?

A case interview is an interview conducted within a business context.

The interviewer will present information about a company and a business problem it faces. These 2 elements together are known as a case.

Case interviews can either be candidate-led or interviewer-led depending on who is expected to steer the order in which different aspects of the case are analyzed.

Deloitte case interviews are predominantly candidate-led which means they’ll be looking to you to take control of solving the case — breaking down the problem, choosing a suitable business framework, and asking for appropriate data to fill in the gaps.

What Type Of Cases Does Deloitte Consulting Use?

The branch of Deloitte Consulting you are applying for can influence the business context you receive in the case. There are 3 parts to Deloitte Consulting:

• Strategy and Operations (S&O) focuses on corporate issues such as organizational strategy, supply-chain improvement, operating model transformation, and business process improvements.
• Technology Consulting focuses on technology issues such as digital strategy, IT program delivery, infrastructure and software solutions, and cybersecurity.
• Human Capital focuses on people issues such as organizational transformation, cultural change, knowledge management, and talent acquisition and development.

So, if you were applying for a Human Capital role you might get an organizational transformation case or, if you were applying to S&O you might get an organizational strategy case

Whichever branch you’re applying to, there are going to be certain skills Deloitte Consulting is looking to test through the case interview process.

What Skills Is Deloitte Consulting Looking to Assess?

Deloitte uses case interviews as a way to assess skills it values in its consultants.

• Structured problem solving
• Analytic skills
• A balance of creativity and practicality

Structured Problem Solving

The ability to carefully think through a problem in a structured and logical way, is a key skillset for consultants. You’ll need to be able to break down a business problem to identify and analyze root causes and potential solutions.

Case interviews test this skill by providing lots of data for you to manage within an unfamiliar business context. Your ability to sort through information to pull out what’s most relevant to the issue will be assessed.

Analytic Skills

Deloitte Consulting will assess your numerical ability during the case interview. Make sure you brush up on your math skills in advance of the interview. Our article on Case Math tells you what to expect.

A Balance of Creativity and Practicality

Case interviews give Deloitte recruiters a chance to see how creative you are when searching for an answer to a thorny problem. Clients hire consultants to solve complex, multi-factor problems, not for mundane issues they can solve themselves.

However, innovative thinking needs to be balanced with good business sense. Suggesting solutions that aren’t viable or attractive to the client shows you lack practical business judgment.

Whatever your recommendation, make sure you highlight the risks associated with it and how those could be managed.

Case interviews can feel challenging — very like tackling a real-life client problem! They’re the perfect environment for interviewers to see how comfortable you are with ambiguity and how resilient you are when things get tough.

Whether that’s grappling with a tricky calculation, or struggling to see how the pieces fit together, make sure you don’t give up. Take a breath and give yourself a moment to clear your head. Then jump back in and keep going.

How Do I Tackle a Deloitte Consulting Case Interview?

There are 4 key stages to tackling any case interview:

• Opening . Make sure you fully understand the client’s problem. Repeat back to the interviewer your understanding of the issue so they have a chance to guide you if you’ve misunderstood. Ask any clarification questions you need.
• Structure . Brainstorm all the issues or factors related to the client’s problem that need to be considered. Be explicit about any underlying assumptions you are making to check their accuracy with your interviewer. Organize your thoughts into a logical sequence to make sure you tackle all of them in your analysis.
• Analysis . Gather and review all the data available to you. Data can be communicated directly by your interviewer or come in the form of exhibit. Complete any calculations required. Identify the most important issues and use this to formulate a recommendation.
• Conclusion . Present your findings to the interviewer and give your final recommendation. State any risks associated with the recommendation and how you’d mitigate them. Outline the next steps and the expected result of taking them.

For more information on using these 4 steps to tackle case interviews see Our Ultimate Guide to Case Interview Prep .

Once you’ve got the 4 stages nailed, it’s time to practice! Doing the thinking is only half the battle in a case interview, you’ve also got to effectively communicate your thoughts.

Practicing with friends, people in your network who are also going through the process, or with former consultants who can coach you through it, is critical to your confidence and success.

Links to Sample Deloitte Case Interviews

You can find links to several Deloitte case interviews in our Case Interview Examples article, as well as dozens of cases from other major consulting firms. The Footloose example has a lot of data exhibits so it’s a good one for practicing how to effectively manage information.

In addition, Deloitte has a very helpful tool on their site that helps you practice case interviews. Each of these cases is 15–20 minutes long and presents you with a real-life business problem and a number of questions.

You can prepare your answers to these cases then compare your thoughts to the Deloitte model answers provided.

Our 6 Tips on Acing the Deloitte Case Interview

Tip 1: keep organized notes.

Deloitte case interviews can last up to an hour and have a lot of information to review. Make sure you take organized notes throughout so you don’t forget anything important or miss something in your analysis.

Neat and logical notes also show you can manage large amounts of data effectively.

Tip 2: Ask Questions to Fill In the Gaps

It’s important to fully understand the problem you’re trying to solve. Don’t be afraid to ask clarification questions or for more data to fill in any gaps in your analysis. Asking questions gives the interviewer insight into how you’re approaching the problem.

Tip 3: Take Time to Organize Your Thoughts

Make sure you take your time during the interview to compose yourself and structure your thoughts. It’s tempting to launch into responding straight away but give yourself space to think through your answer first to make sure you don’t miss something or forget an important point.

Tip 4: Utilize a Framework and Develop a Hypothesis

Using a business framework or an issue tree helps you drill down into the heart of the problem. This means you’re more likely to develop a hypothesis that solves the key issue the client is facing.

Keep referring back to your issue tree and hypothesis during your Deloitte interview to make sure your analysis is logical and hasn’t gone down a rabbit hole!

Tip 5: Structure Your Recommendation

Present your analysis in a clear and structured way. Start with the main takeaway — your recommendation. Then walk your Deloitte interviewer through your analysis in a logical way, highlighting the most important points and explaining how they led you to draw the conclusion you have.

Share any assumptions you’ve made to reach your recommendation and also any associated risks. This shows you’ve thought more broadly about the problem in the context of the business as a whole.

Tip 6: Don’t Forget to Breathe!

While case interviews can feel daunting, try not to panic. Viewing the case as a business conversation that showcases your ability to think through a problem, rather than as something that must be solved, can ease the pressure.

As part of the final round assessment, Deloitte Consulting uses group case interviews.

As many of the top consulting firms don’t use group case interviews, candidates can be unsure of what to expect. But, don’t worry, we’ve got you covered!

What Happens In the Deloitte Group Case Interview

In Deloitte group case interviews you’ll be organized into a group with 3-6 other candidates. The group will be presented with information about a case that they’ll need to work together to solve.

• For the first 10 minutes, you’ll work alone, or in a pair, to review the information and prepare your thoughts.
• The group will then discuss the problem for 20 minutes, sharing analysis, and preparing a recommendation for the client. During this discussion, interviewers will observe the group to see how you interact with each other.
• For the final 20 minutes, interviewers will ask questions of the group.

Our Top Tips for the Deloitte Group Interview

Group case interviews are your opportunity to stand out against other candidates. Interviewers will be observing the group dynamics and looking for great communication skills, strong analysis, and leadership.

Here are our top tips:

• Add value with your contribution . Everyone knows interviewers are looking for participation but it’s not enough just to speak up during the group case interview — what you say matters. Your contribution should add fresh insights to what’s already been said. This shows good listening and analysis skills.
• Showcase your leadership ability . Leadership isn’t just about speaking first or dominating the conversation. Facilitate the conversation and bring other team members into the discussion if they haven’t had a chance to speak. This shows you value the contribution of others, which links to one of Deloitte’s core values: foster inclusion . Do be proactive about proposing points for discussion, managing time, and bringing the group back on track if you lose focus.
• Recognize others as teammates . While demonstrating leadership is important, it’s equally important to remember you’re trying to deliver value to the client. Make contributions that bring the group closer to a recommendation — don’t sidetrack the discussion just to stand out. Acknowledge the great ideas of others — which shows confidence — and then add to them.
• Summarize the discussion . At the end of the group discussion, summarize the main points of the conversation and state the group’s recommendation. You can also do this throughout the interview, any time when a lot of points have been discussed and a quick recap would be helpful.

This is important as it shows good communication skills and the ability to synthesize large amounts of data. It also makes sure that everyone’s on the same page and clear about the next steps, which is critical when dealing with real-life clients.

Deloitte Consulting Behavioral Interview Question

The Deloitte behavioral interview has 2 types of questions: fit questions and personal experience questions.

Fit questions help interviewers judge whether you’d fit into the Deloitte culture. Personal experience questions help them judge whether your skills and personal qualities match those they’re looking for in a consultant.

Top 3 Fit Questions and How To Ace Them

1. Why Do You Want To Work For Deloitte Consulting?

This is the top fit question and for good reason. Deloitte Consulting cares about recruiting people who really want to work there and value its specific culture and approach. 

Consulting firms invest heavily in developing their new recruits and they need you to stay long enough to make that investment worth it. So they’re expecting you to join the firm with eyes wide open.

Tackle this question by having a few good reasons why Deloitte is the company for you. The best answers are personal to you. 

Maybe you’ve been inspired by someone you’ve met from the firm. Or there’s something about Deloitte core values that really matters to you. That’s what recruiters want to hear about.

Deloitte Consulting’s core values are:

• Lead the way
• Serve with integrity
• Take care of each other
• Foster inclusion
• Collaborate for measurable impact

2. Why Consulting?

Consulting can be intense, so consulting firms are genuinely concerned that you understand what’s required of you and have the potential to meet the challenge. This question is your chance to explain why consulting is the career for you.

Whether that’s because you get to work with senior management early in your career or you’re excited about the opportunity to make a difference, make sure you’re clear on your motivation.

3. Tell Me Something About You That’s Not On Your Resume.

It’s easy to curate a polished, professional profile on paper. But interviewers are interested in who you are outside of work too.

This question provides an opportunity for you to talk about something you’re passionate about, and show a more human side. Bear in mind the Deloitte Consulting core values when you’re considering how you’d tackle this question.

For example, maybe you organize a community garden to provide food to local families. Or you spend time as a reading volunteer at your local care home.

Contributions you make as a volunteer can demonstrate your leadership capability as well as other ways you create a positive impact in your daily life.

Personal Experience Questions And How to Approach Them

A typical personal experience question starts with “Tell me about a time when…”

They help the interviewer see how your experience has helped you build the skills that make you suitable for consulting.

Examples include:

• Tell me about a time you disagreed with someone and how you worked through the problem.
• Tell me about a time when you led a team to solve a problem.
• Give me an example of when you had to deal with adversity. How did you resolve it?
• Tell me about a time when you changed someone’s mind on an important topic.
• How did you go about deciding on your class project recommendation?

The best approach to tackling a personal experience question is to tell stories. Stories are engaging and stick in the interviewer’s mind even after a long day.

However, like everything else in the case interview, your answer should be well-thought-through and structured. Don’t just launch into your story without thinking.

We recommend using the A STAR(E) framework to make sure your story is impactful and covers all the main points.

Using the A STAR(E) Framework

The A STAR(E) framework covers the following points:

• Answer . Start with a clear, short answer to the question.
• Situation . Give your story some context. Who were the people involved in the story? When and where did it take place?
• Tension . What was the problem you faced? The conflict or challenge?
• Action . What action did you take to resolve the issue?
• Result . What happened as a result of your action?
• Effect . What did you learn?

The (E) is in parentheses because this won’t be relevant to every story.

Remember the behavioral interview is also an important opportunity to learn more about Deloitte so you can feel confident you’re making the right choice.

In fact, that’s one of 6 key things Deloitte Consulting encourages candidates to bear in mind when tackling the behavioral interview:

• Share personal experiences to illustrate your critical skills and achievements.
• Describe experiences and career/life periods reflected in your resume.
• Focus on the positives of all your past experiences and remain optimistic.
• Use this discussion to learn more about Deloitte Consulting.
• Relax, be yourself, and help us get to know you.
• Use your time wisely; it’s your time, make sure you get your points across.

Deloitte Case Interview Guide 2024: Criteria, Technique & Tips

Deloitte is one of the “ Big Four ” – the world's four largest accounting and consulting firms. Competitive recruitment processes aside, successful candidates must pass through challenging consulting interviews called “ Case Interviews ”.

In this article, you will be guided through the building blocks of Deloitte’s Case Interviews, with special tips, techniques, examples, and more!

Overview of Deloitte case interview

Deloitte case interviews are often candidate-led . The candidate will be leading or taking control of every step ahead to solve the case. This includes structuring the problem, drawing frameworks, asking for data, synthesizing findings, and proposing solutions. 

The Deloitte case interview occurs in the last stages of Deloitte’s recruitment process. Candidates will encounter two Deloitte case interview types: individual case interview and group case interview.

What does Deloitte look for in candidates?

During the Deloitte case interviews, candidates are expected to demonstrate three crucial traits of a consultant: problem-solving skills, analytical ability, and strategic and logical thinking. 

Problem-solving skills: The point of hiring consultants is that they can break down business problems better than anyone else. The entire consulting industry rests on consultants' unique analytical problem-solving abilities.

Analytical ability: Strong analytical ability enables consultants to analyze complex business problems and generate meaningful insights. They can apply these skills to break down problems by identifying patterns, trends, and root causes, making them more manageable and easier to tackle. 

Strategic and logical thinking: Strategic and logical thinking enables consultants to make informed decisions, anticipate future change, and navigate complex business landscapes to deliver optimal solutions for their clients.

Deloitte case interviews occur in the last stage of the recruitment process

Deloitte recruitment process consists of three main stages: (1) online application, (2) online tests, and (3) interviews .

The whole process can take up to 2-3 months, for a job starting 6-12 months after application. Newer offices can speed up the process to meet the demands.

Online Application: The most important thing in this first stage is to prepare an outstanding consulting-style resume. Our free consulting resume templates helped thousands of candidates reach their consultant dream.

Online Tests: As part of the online application, you will have to sit through five tests. These include: Cognitive Test, Verbal Reasoning Ability Test , Numerical Reasoning Ability Test , Logical Reasoning Ability Test , and Psychometric Questionnaire.

Interviews: The candidate will go through two interview rounds. The first round will generally be a phone screen/face-to-face initial interview with a Talent Acquisition team member. The second round will be individual and group case interviews. The number of interviews depends on the service line and position candidates apply for.

In Deloitte case interviews, candidates usually have to go through one or two 30-60 minute individual case interviews and one 1-hour group case interview.

Deloitte individual and group case interview

Deloitte individual case interview is the standard type of case interview. Candidates will receive the case from the interviewer, which they need to define the issue and give solutions. Usually, there will be two cases for a 45-60 minutes session.

Deloitte group case interview is similar to other group case interviews at BCG, Bain, and three other Big Four firms. A group case interview will usually go through five stages:

Stage 1: You will be assigned to a group of 3–6 applicants.

Stage 2: The group will be given a case and relevant information to solve.

Stage 3: You will be given 10 minutes to examine the case and prepare alone or in collaboration with another team member.

Stage 4: The group will discuss case questions for 20 minutes while the interviewers observe and take notes.

Stage 5: The interviewers will ask questions about the cases in the next 20 minutes.

Deloitte case interview format is candidate-led

The Deloitte case interview is often a candidate-led case interview . The interviewer will present the issue and require the applicant to lead and control every stage to solve the case: structure the problem, develop frameworks, request data, synthesize results, and provide solutions.

Candidate-led cases focus on one big problem

In candidate-led cases, you have to figure out how to solve a big case . This is opposed to interviewer-led cases , where the interviewer presents smaller questions about the case to the candidate.

You should take a top-down approach - break the problem into small parts of the issue tree and tackle each one at a time. 

Candidate-led cases are flexible

In a candidate-led interview, the candidate can choose their own suitable approach.

The interviewer usually forms a “universe” of data on the client and their problems for you to explore. If your issue trees and solutions seem to go beyond the given information (in a good direction), the interviewer can “make up” new information on the spot to help you solve the case in your way.

Candidate-led cases focus less on being right

In a candidate-led interview, you put less emphasis on giving a definite “correct” answer and focus more on creating a structured, reasonable approach .

An “acceptable” margin of error is allowed in the candidate-led interview since you must break down the problems by yourself without much assistance from the interviewer.

Fundamental framework to solve Deloitte case interview

To solve the Deloitte case interview, you need to develop an issue tree to break down your case. To create a suitable issue tree, you can use common frameworks for case interviews: Profitability framework, Business situation framework, McKinsey M&A framework, 4P/7P marketing mix, and Porter’s five forces model. 

To further enhance your case interview performance, you can apply five effective tools (or mini-frameworks): External vs. Internal, Quantitative vs. Qualitative, Costs vs. Benefits, 2x2 Matrix, and SWOT analysis. 

Five common frameworks for case interview

Profitability framework is mostly used to mathematically break down problems before switching to the qualitative framework for solutions. To use the profitability framework, candidates will split profits into revenues and costs.

Business situation framework is used to analyze a company situation in four areas - Company, Competitor, Customer, and Products (3C-1P). This 3C-1P framework is flexible for many purposes; however, it may be too generic and need customization depending on the situation. 

McKinsey M&A framework is used to assess a proposed merger and/or acquisition on three aspects: standalone values of each involved company, their synergy, and other factors. This framework is MECE and promotes customizations, and is one of the best M&A frameworks. 

4P/7P marketing mix in marketing for tangible work analyzes the 4P - Product, Price, Place, and Promotion; while in service marketing, three other Ps will be added in - People, Process, and Physical evidence. This framework focuses on the marketing aspect, hence unsuitable for multi-function strategies. 

Porter’s five forces model analyzes the industry surrounding a business in five aspects - Suppliers, Customers, Competitors, New entrants, and Substitutes. This framework is used to get an industry overview and understand the client’s context.

Five effective tools for case interview

External vs. Internal method is quick and easy to segment information about a particular entity. The internal branch concerns what is inside or intrinsic to the entity, and the external branch concerns outside factors. 

Qualitative vs. Quantitative mini-framework is used for evaluations. Dividing items into two MECE groups reduces confusion and minimizes the risk of missing an essential item. 

Cost vs. Benefit in the decision-making process is very straightforward - if the benefits of an option outweigh its costs, that option can be chosen.

2x2 Matrix is a decision-making tool where options are examined using two criteria, each forming an axis of the matrix. 

SWOT analysis mini-framework is seldom used in case interviews for being too generic. However, it can be used to evaluate a company’s positioning within the industry context quickly. 

You can check our free article on Case Interview Framework to understand the common framework used in the case interview.

How to Prepare for Deloitte Case Interviews

Step 1: Familiarize with interviewer-led case examples

Deloitte has several sample cases on its website with guides and tips. You can also examine examples of similar candidate-led case interviews from BCG and Bain to familiarize yourself with the case flow and how to interact with the interviewer.

Step 2: Practice consulting math

Consultants work with quantitative data dozens of times a day. Pulling out a calculator every time they need to calculate something takes too long, and doing so in negotiations looks terrible.

This is why interviewers place such high emphasis on the mental math skills of prospective consultants.

In the beginning, consulting math can be difficult for some; nonetheless, I have a few tips for you to ease the process and still practice effectively:

Use Your Head: Do all your daily calculations mentally unless an EXACT answer is required.

Flatten the Learning Curve: At the start, scratch paper and a 5% margin of error help; once you are confident, discard the paper and narrow down the margin.

Establish a routine: Allocate some time for daily practice. This may seem hard at first, but you can feel the improvement once you’ve overcome the inertia.

Step 3: Develop Business Intuition

Having business intuition significantly sharpens your performance in case interviews.

Working on intuition is a gradual process that takes practice every day. You can improve your business intuition in two ways:

Written Sources: I suggest reading business papers daily; you can also visit McKinsey, Bain, and BCG websites for their excellent articles. Beware though – it’s not the pages you read that count, but the insights you draw from them.

First-hand Experience and Observations: Don’t just come to your workplace to work; examine what senior managers are doing – what’s the rationale for their decision, and how has it impacted the organization?

Step 4: Learn the fundamentals and frameworks

Practice using hypotheses and issue trees , the MECE principle , and the frameworks until you are comfortable using them– they are the backbone of candidate-led case interviews.

It might be tempting at first to go straight for the frameworks – if you make this common mistake, prepare for some unpleasant surprises in the interview. Frameworks need a lot of customizations to fit with real cases, and to customize effectively, you need that fundamental knowledge.

Of course, don’t draw an issue tree for all your daily problems – that’s just overkill, but remember to take a structured approach and picture an issue tree in your head while searching for your keys.

Step 5: Perform mock interviews

The best way to get good at something is to do it.

Best to find yourself a former consultant to help you practice; they’ve been through countless case interviews, both real and mock, and they know what’s required of a candidate, so they’re the best people to run your simulations with.

Study your cases down to the smallest details. Replay them repeatedly, take notes of the interviewer’s feedback, and look for other areas you can improve.

Tips for the perfect Deloitte case interview

Nine tips for the perfect deloitte individual case interview.

Tip #1: Understand the procedure of a candidate-led case interview

There is a five-step procedure to approach the PwC candidate-led case interview. 

Taking the case: You need to take notes on all information regarding the clients and the case situation. Keep your notes organized to refer back to them easier.

Clarifying: You will have time to gain more information and/or clarify the points you haven’t fully understood about the cases.

Structuring: You will need to break down the case business problem into smaller components to create the issue tree , allowing you to solve it in an effective and cohesive manner.

Hypothesizing: You must develop the hypothesis based on evidence and available data about the problems and find the root cause. If the initial hypothesis in a branch of the issue tree no longer makes sense, go to the next branch. If the hypothesis matches, stick to it to find the root causes and solutions.

Pitching: The pitch is your case interview's final product, where you summarize all findings and recommendations to solve the case. You need to deliver the pitch in a structured, top-down manner.

Tip #2: Have a perfect case opening

There are four reasons to make a good case opening while you deliver your case interview:

First, it shows you have complete control of the upcoming problem-solving process, which is critical in candidate-led cases.

Second, you can demonstrate your whole leadership and relationships with proactiveness - aligning yourself with PwC's five qualities mentioned above.

Third, a good case opening creates a great first impression. Consultants are expected to perfect everything from the beginning to the end, so this could make a good head start for a 30-minute interview.

Finally, this is an opportunity to align during the interview. After the interviewer has outlined the case details, explain the case to the interviewer in your own words to ensure you grasp the issue and align with the interviewer.

Tip #3: Map your next moves

Pause occasionally to summarize where you are and where you’re going next. It gives you a sense of direction and authority; additionally, you get plus points in the interview for an organized approach. 

This also gives your interviewer a chance to help you with your mistake. If your interviewer gives you advice, take it – assume it’s intended to be helpful.

Tip #4: Be consistent with your intended hypotheses

Always speak with the current hypothesis in mind, and that hypothesis must be in the issue tree. The sole purpose of the hypothesis-driven approach is to have your efforts and problem-solving steps guided and structured. 

Therefore, to avoid being overwhelmed by piles of data in your case interview, do a sanity check by returning to your issue tree. If your action does not correspond to your present place on it, go back immediately!

Tip #5: Deliver your pitch in one structured manner

This is the most important tip because you need to show that you own the consultant qualities - being structured and straight to the point. Present your analyses in a perfect, insightful, top-down, concise, and captivating final pitch.

Find a way to structure the problem; this will guide your discussion with the interviewer. Briefly explain the framework you plan to use, allowing the interviewer to comment. In general, the simpler the framework, the better. Once the interviewer endorses your framework, stick to it.

To structure your speech:

Begin with a summary line that states the key takeaway/intention.

Separate what you want to say into distinct sections. As much as possible, avoid jumping back and forth between items.

Number your items so you and your interviewer can keep track of them. It's even better to specify how many things you'll be discussing beforehand.

Make your recommendation based on the conclusions you reached from your discussion, even if you are unsure with so little data and time to discuss all the issues.

Tip #6: Make a personalized script

Make a script of what you will say and rehearse it a hundred times. Practice all of the formulaic phrases, such as the opening or data request. With enough practice, those lines will become second nature to you.

The secret to seeming professional in a case interview is to talk in a systematic and formal manner. Using scripts also saves brainpower, which you will undoubtedly want in case interviews.

Tip #7: Keep your notes organized

Neat note-taking greatly assists with your train of thought, making storing and organizing information easier. You're also demonstrating to the interviewer that you're well-organized and meticulous.

Divide your notes into three categories to make them easier to read and interpret: data, presentation, and scratch paper. When the interview begins, take three pieces of paper and name them appropriately. Here is the content that should be on each type of note:

Datasheet: note down and process any data the interviewer gives you and your calculations.

Presentation sheets: draft things you’ll say to the interviewer.

Scratch paper: anything else you need to write, such as brainstorming ideas.

Tip #8: Avoid long pauses

Take a minute to think; don't be afraid of the silence. If you need silence to think, ask for a timeout or announce think-out-loud mode.

However, taking it too long will backfire, especially if you can’t come up with something worthy of the long wait. Use the pause prudently, and always try to think as fast as possible while still being “correct”. 

Tip #9: Find and ask for more insights

Try your best to be in-depth and comprehensive with your analysis. Always ask yourself, “Am I overlooking something?” and “Can I drill down further?”. 

This is also helpful when you are stuck in your analysis. You can try asking for insights from the interviewer (remember to state your purpose clearly) like this:

If you have a piece of data and don’t know what to make of it, ask for benchmarks to put the data into perspective.

If you are unsure which framework to employ, consider "segmentation" - look at how the customer or the industry often segments that item. If you need to know how they do it, ask the interviewer.

When you cannot see the problems in the case (probably resulting from the “MECE” of your issue tree), ask the interviewer nicely for a way out.

However, remember to manage your time well. If you take too long, the interviewer might force you to move on, and you will lose the time to solve the case holistically.

Four tips for the perfect Deloitte group case interview

You are being evaluated with many other candidates in group case interviews. So, how can you make yourself stand out? Here are six helpful recommendations to ace a group case interview.

Tip #1: Manage your ideas

Take your time processing the question and developing an orderly and structured response. If you allow yourself time to analyze, your answer will be more robust.

Ask the interviewer for a few minutes to organize your thoughts, but avoid excessive silence when necessary.

Try not to intervene forcefully while others are speaking in group interviews. If you have a brilliant idea, write it down. That way, the flash of brightness won't fade from your memory.

Tip #2: Decide whether your role is a leader or team member.

This is the decision that needs to be made on the spot - other candidates are going for the “leadership role” of the discussion. If you want to lead, go right at it. However, you can still demonstrate desirable consultant qualities even as a team member.

If you decide to be the team leader, emphasize your facilitator role.

It’s a good idea to be proactive in proposing what topics to discuss, in what order they should be addressed, and how much time should be allocated to each issue. You can bring the group’s focus back together if the group gets off track.

By the end of the group discussion, make a point to compile people's different points. This puts you in a position to bring everyone together and ensure all candidates are on the same page.

If you decide to be a team member, speak to add value.

Candidates will take turns presenting answers to the interviewer. Before it’s your turn, listen carefully to other people’s answers and the interviewer’s feedback.

This way, you can add valuable and helpful insights to the discussion. Remember, good points go to the quality of what you say, not the number of times you speak up.

Tip #3: Ask good questions

Asking outstanding questions will set you apart. It demonstrates that you are attentive and willing to learn more. Great questions often target one or more objectives: explaining an unfamiliar term, clarifying the issue's purpose, or expanding the team's understanding of the setting or business.

Tip #4: View others as teammates

Seeing people as colleagues puts you in a collaborative attitude, which allows you to work successfully with others. You look to be both a helpful leader and a team player in this manner.

You can be the first to answer your interviewer's question to avoid seeming timid. You can encourage co-interviewees by emphasizing their excellent ideas, adding what you believe is lacking, and explaining your reasoning.

Deloitte First Interview and Case Study

This interview is usually part of the recruitment process for BrightStart, the summer vacation schemes and the graduate programme applicants. This interview is designed to learn more about you and your suitability for the role you have applied for.

The interview also contains the Deloitte case study for you to discuss with your interviewers. Ahead of your interview, you will be given a short period of time to read a case study and think about some answers to a set of guide questions. The information contained in the case study may include numerical information as well as articles.

Once in the interview room, the interviewer will ask you questions about the case study for you to discuss with them. You may find it useful to write down your thoughts to take into the interview.

Ahead of this interview, you are advised to prepare examples of activities or pieces of work you have been involved with, where you have built up into a project over a large period of time. The interviewers are looking for evidence of your role, and how you worked with others to achieve your goals.

Use the STAR method (situation, task, action, result) to organise your answers and ensure that you don’t leave anything out. You should also read up on Deloitte, as well as any news concerning the company. Be prepared to answer questions about why you have chosen this speciality.

Applicants for consulting positions will have a group exercise at this interview.

Deloitte Competency-Based Interviews

Applicants for the Deloitte professional hire positions can expect to be invited to at least one competency-based interview.

In a competency-based interview, you are asked questions designed to allow you to demonstrate that you have the skills to do the jobs.

These skills are in the job description and person specification for the role you are applying to, as well as Deloitte’s core competencies and values.

Prepare in advance for the competency-based interviews by thinking up examples against each competency.

Develop examples around the STAR method (situation, task, action, result) to ensure that you have covered all the necessary information about your role in this example and how you contributed to the outcome.

Final Interview with Presentation

The final or Deloitte partner interview is usually the last part of the recruitment process for Deloitte BrightStart and Deloitte graduate programme applicants.

This is a one-hour interview in which you will give a pre-prepared presentation. This interview will focus on your values and how you can contribute to Deloitte.

You should prepare examples demonstrating what matters to you, how you can contribute and so on. As always, prepare these examples using the STAR method (situation, task, action, result).

Other questions in the interview may test your commercial awareness, so prepare by reading the news, thinking about the implications for Deloitte; reading up on the trade press; reading the Deloitte website, and making sure that you know about the company’s departments, work and competitors.

You should also prepare questions to ask in the interview. Make sure they are not too obvious or could be found easily by looking at the website.

Deloitte Presentation

Ahead of this interview you are sent a topic and asked to prepare a five-minute presentation to give over to your Partner interviewer.

Make sure you understand what is in your presentation as you will be asked questions at the end. You are allowed to take a handout for the interviewer, but you will not have access to any IT equipment.

Topics will depend on the area you are applying to, but include:

• Your take on European audit reforms
• Have corporations learnt from the recession
• Regulatory impact on businesses
• How will audit have to adapt going forward

Read more tips about how to give a presentation on our presentations pages .

Deloitte Interview Questions

The variety of interviews and range of interviewers at Deloitte mean that there are many questions you may experience. Questions at interviews may be situational, behavioural, about you or your choices.

Below is a selection of questions that may span any number of interviews:

• Why Deloitte, and why this job/ department?
• Tell me about a time you achieved your goals, and how you went about doing it.
• What challenges are Deloitte currently facing?
• Tell me about a recent news item that has interested you, and why.
• Tell about a recent project in detail.
• What could you contribute to Deloitte?
• Tell me about one of our clients.

For more information about common interview questions and how to approach them, read our free guide to interviews .

Deloitte Interview Preparation

There are several stages to your Deloitte interview preparation.

Start by reviewing your application form and refreshing your memory on what you said about yourself. Expand examples from your form, or think of more examples from your experience to answer similar questions in the interview.

Review Deloitte’s competencies , and prepare examples where you have demonstrated those competencies. Think about answers to some of the more obvious interview questions.

Next, read up about Deloitte from the website and also any news or trade press articles you can find about the company. Think commercially when preparing, and about the implications of what you are reading for Deloitte.

Rehearse giving over your answers so that you can get the experience of saying the answers out loud. You can do this in front of a mirror, or with a friend, but a mock interview is an even better way to prepare.

Our interview preparation package  is a great way to prepare for your interview with a trained assessor who can give you pointers on your performance, and tips for improving in your real interview.

Deloitte Group Exercise

Applicants for consultancy positions in the BrightStart and graduate scheme are invited to a group exercise at the same time as the first interview. Professional hire applicants may also be invited to take part in an exercise at some point in the recruitment process.

In this exercise, you are given a group brief and 5 minutes to read through it on your own. After the five minutes are up, your group has 20 minutes to discuss the topic as a group, and come up with a conclusion. The individual briefs will all be different with each group member required to put forward a case for something else.

This means that you have to take part and contribute fully to the group. Your group is allowed to choose just one option, so you need to be prepared to listen to the others and evaluate whether another option is better. The group exercise is designed to have you working as a team, so your role is to be an effective team member.

Prepare your group exercise strategy in advance and think about approaches for making sure your perspective is put forward without taking over the entire conversation. Also, think about how to deal with others who want to talk and not listen. Get more tips for your group exercise with JobTestPrep.

Deloitte Case Study

The case study is one of the most demanding tests you will have to take during Deloitte's assessment centre. The test comprises an abundance of fictitious documents depicting a company facing business decisions. You will need to analyse the case in hand and devise a recommended plan of action.

You are then asked to give a brief written report or make a short presentation of your recommendations. The key to success in this test is working fast through the documents, prioritising and identifying the key issues.

How to prepare for this exercise?

JobTestPrep's new case study practice pack is designed to help you prepare for any case study. Featuring two full case study exercises, a study guide and scoring tips, this pack will give you all the preparation you need for your Deloitte's case study exercise.  Find out more here .

Deloitte's E-tray exercise characteristics

Deloitte's e-tray exercise is designed to assess a multitude of skills among which are decision-making, planning and organising, problem-solving and managerial abilities.

In the exercise, you are given details about a job description that usually includes some managerial responsibilities. You are then introduced to a simulated online workplace environment including an email inbox, word documents and presentations.

After reviewing an excessive amount of information regarding your position, you will be asked to answer emails, analyse data and address matters of pressing importance. While most questions will be in multiple-choice format, the final questions will require your written response on the following topics:

• Prepare an email communication on a particular issue you were presented with during the exercise. It will normally be an issue you may come across on the job. 
• Advise what would be the most efficient and appropriate way to deal with a series of emails that appear in your inbox.

As part of these written responses, you will be asked to explain the course of action you have chosen and discuss the factors that have led you to the proposed resolution.

How to practice for this exercise?

JobTestPrep offers an extensive online practice pack that follows the same concepts and question types that appear in Deloitte's e-tray exercise. You get immediate online access to two smart practice sessions that simulate similar job descriptions and tasks given in a real e-tray test.

Each test includes a score report, comprehensive explanations to questions and solving tips for performing better on the real test.

How to prepare for deloitte's interview questions.

Discover targetjobs’ advice for crafting strong answers to Deloitte’s interview questions and improve your prospects of securing a graduate role at the ‘Big 4’ consultancy.

Advice: Deloitte interview questions | Answering Deloitte’s interview questions | Deloitte job simulation ‘video interview-style’ questions | Get a targetjobs career boost

Deloitte interviews tend to last up to an hour and from the get go the firm reminds candidates to relax, listen carefully and express themselves clearly. If you make it to the final stage of Deloitte’s graduate, summer internship or placement year recruitment process, and you’ll take part in a live video interview with a hiring manager from the respective business area.

The firm also advises applicants to ‘review your immersive online assessment feedback report and consider the questions you’re likely to be asked’ ahead of attending an interview.

Deloitte interview questions

Deloitte’s interview questions include a mix of different question types, which include:

• Competency-based questions to give an insight into the skills you have demonstrated in the past. These are typically answered using the ‘STAR method’ to provide details of the s ituation, t ask you faced, a ctions you took and r esult achieved. Learn more about the STAR method and competency-based questions here .
• Motivational questions (a form of strengths-based interview questions ) to help Deloitte’s recruiters to understand what drives you and what interests you about Deloitte and the role you have applied for.
• Scenario-based questions (another type of strengths-based questions) asking you to consider what you think you would do in hypothetical work-based situations. These allow Deloitte to gain an understanding of your behavioural instincts in a work setting.
• Questions about you to help the recruiters get to know what’s important to you, how you like to work and whether this aligns with Deloitte’s values. Learn more about answering values-based interview questions in this article .
• Topical questions to give an insight into your thoughts and ideas relating to topics that present issues for Deloitte, society or both. These types of questions often call upon your commercial awareness .

How to answer past Deloitte Interview questions

Below are just a few examples of the kinds of questions you could be asked at a graduate, summer internship or placement year interview at Deloitte, as well as advice on how to use your answers to show recruiters that you possess the traits they’re looking for.

The questions you’re asked may well be different, but practising how you’d answer these (and perhaps using them for a test run with a friend playing the part of the interviewer) will be great preparation for your Deloitte interview.

Read on or jump to a question:

• Describe a time you took on a position of leadership .
• Why Deloitte ?
• What would you do if you were running Deloitte for a day ?
• What challenges is Deloitte currently facing ?
• What does the ACA qualification (or another professional qualification) involve ?

Past Deloitte interview question 1: Describe a time that you took on a position of leadership

How to approach the question : Deloitte champions the concept of ‘human-centred’ leadership and also states that leaders should be able to ‘understand and influence’ their environment. This doesn’t mean that your answer needs to portray you as an already well-developed leader, but you should strive to provide an example that demonstrates that you put your group members first, that you have understood the task at hand and made decisions that helped the group achieve its aims.

For example, perhaps during a university group project you volunteered to be the team leader and delegated responsibilities based on the tasks that the other individual group members would most enjoy completing. An example along these lines would show that you ‘put your people first’ and understood your environment by aligning tasks with team member’s strengths.

Don’t say : or imply that your leadership was the sole reason for your group’s success. At the core of human-centred leadership is the practice of empowering other members within the team to make impactful decisions that help to achieve the collective goal.

Past Deloitte interview question 2: Why Deloitte?

How to approach the question : you can demonstrate your commercial awareness and career motivation by giving a couple of examples about projects that Deloitte or, even better, your prospective Deloitte business area has been or is currently involved in.

The points you make should show that you have thoroughly researched the company. Don’t just recant Deloitte’s broad turnover or quarterly figures, hone in on individual projects, case studies and other commercial developments and Deloitte’s values and think about how these relate to your interest in the role and your career aspirations.

Perhaps your main motivation is the potential to work with a range of clients – in which case, you’ll need to mention specific clients and why their projects piqued your interest.

Don’t say : anything to do with a ‘strong reputation for excellence’, ‘the chance to work with pioneers in their fields’, ‘working within a true meritocracy’ or anything that sounds equally sycophantic.

Note that this interview question might be phrased as ‘Why do you want to work for Deloitte out of all the Big 4 professional services firms?’.

See our article on answering the interview question ‘ Why are you interested in this position? ’ for more in-depth advice for tackling motivational ‘ why?’ questions.

Learn more about Deloitte and find career opportunities with the employer via its organisation hub on targetjobs.

Past Deloitte interview question 3: If you were running Deloitte for a day, what would you do?

How to approach the question : Deloitte is looking for someone who can make and implement clear decisions and has sound planning and organisational skills. You will likely face follow-up questions that challenge your opinions; your interviewer will play devil’s advocate to make sure you have considered things from every angle.

You could suggest, for example, that you would identify a number of areas for the business to expand into within the technology sector. If you gave an example, you would have to consider the potential impact on Deloitte’s other geographical markets and additional service lines, as well as the long-term impact on business development in these areas.

Don’t say : you would make wholesale changes and focus only on one or two markets alone. The example above highlights the technology sector but remember to think about how your actions here impact on the rest of the business. You can easily fall into the trap of focusing only on what you are interested in, rather than what’s in the best interests of the international business as a whole.

Our advice feature on the 12 skills that consulting recruiters want will give you an in-depth insight into the competencies that your answer to this Deloitte interview question should display.

Past Deloitte interview question 4: What challenges is Deloitte currently facing?

How to approach the question : this is a particularly fun question because you can really sell yourself in terms of the value you could bring to Deloitte and highlight your commercial awareness. The best place to start is the ‘newsroom’ section of the employer’s website. You need to take some company news and spin it around to relate it to the role. Just relaying a piece of news that the recruiters are already aware of isn’t enough; you need then to be able to say, ‘What this means for the company is X’, and, even better, ‘This is what it means for the division I’m applying to, and how it might affect things we have to consider here in the UK’.

Don’t say : that the current economic climate makes things difficult for Deloitte. You’ll need to know plenty about local, national and international economics, certainly, but this is the bare minimum – you need to be more specific. Remember also, that some of Deloitte’s work will be counter-cyclical, which might give you more food for an answer.

Be sure to check out our article on commercial awareness for more tips on using it to answer questions about the broader market.

Past Deloitte interview question 5: What does the ACA qualification (or another professional qualification) involve?

How to approach the question : everyone is going to go to Deloitte’s website and note down its content. The problem with this is that Deloitte’s website doesn’t actually provide much information about the ACA qualification, aside from the absolute basics. A more interesting candidate would investigate the qualification they would be studying as a trainee at Deloitte to gain a deeper understanding of the course modules and how these will help them to progress professionally.

A more interesting candidate would also investigate alternative qualifications to get a better idea of why Deloitte has chosen a specific one. In the case of accounting, for example, other highly-regarded professional qualifications exist, such as the ACCA and CIMA. Knowing what differentiates these from the ACA will help your answer.

A word on Deloitte’s job simulation ‘video-interview style’ questions

Before being invited to your Deloitte interview, you’ll need to pass the Deloitte job simulation. This is an online assessment where you will answer questions based on workplace scenarios related to the role you’re applying for.

You will answer questions in multiple formats, including ones that require you to record and upload responses using a webcam in the same way you would for a pre-recorded video interview. However, unlike a typical pe-recorded interview, which asks you a range of interview questions, past Deloitte applicants report that the job simulation video questions are focused on a hypothetical case study.

Regardless of the questions asked, you should treat the video questions in the job simulation in the same fashion as you would a standard pre-recorded video interview – so make sure to test your tech beforehand and dress for the part.

Deloitte First Interview and Case Study

This interview is usually part of the recruitment process for BrightStart, the summer vacation schemes and the graduate programme applicants. This interview is designed to learn more about you and your suitability for the role you have applied for.

The interview also contains the Deloitte case study for you to discuss with your interviewers. Ahead of your interview, you will be given a short period of time to read a case study and think about some answers to a set of guide questions. The information contained in the case study may include numerical information as well as articles.

Once in the interview room, the interviewer will ask you questions about the case study for you to discuss with them. You may find it useful to write down your thoughts to take into the interview.

Ahead of this interview, you are advised to prepare examples of activities or pieces of work you have been involved with, where you have built up into a project over a large period of time. The interviewers are looking for evidence of your role, and how you worked with others to achieve your goals.

Use the STAR method (situation, task, action, result) to organise your answers and ensure that you don’t leave anything out. You should also read up on Deloitte, as well as any news concerning the company. Be prepared to answer questions about why you have chosen this speciality.

Applicants for consulting positions will have a group exercise at this interview.

Deloitte Competency-Based Interviews

Applicants for the Deloitte professional hire positions can expect to be invited to at least one competency-based interview.

In a competency-based interview, you are asked questions designed to allow you to demonstrate that you have the skills to do the jobs.

These skills are in the job description and person specification for the role you are applying to, as well as Deloitte’s core competencies and values.

Prepare in advance for the competency-based interviews by thinking up examples against each competency.

Develop examples around the STAR method (situation, task, action, result) to ensure that you have covered all the necessary information about your role in this example and how you contributed to the outcome.

Final Interview with Presentation

The final or Deloitte partner interview is usually the last part of the recruitment process for Deloitte BrightStart and Deloitte graduate programme applicants.

This is a one-hour interview in which you will give a pre-prepared presentation. This interview will focus on your values and how you can contribute to Deloitte.

You should prepare examples demonstrating what matters to you, how you can contribute and so on. As always, prepare these examples using the STAR method (situation, task, action, result).

Other questions in the interview may test your commercial awareness, so prepare by reading the news, thinking about the implications for Deloitte; reading up on the trade press; reading the Deloitte website, and making sure that you know about the company’s departments, work and competitors.

You should also prepare questions to ask in the interview. Make sure they are not too obvious or could be found easily by looking at the website.

Deloitte Presentation

Ahead of this interview you are sent a topic and asked to prepare a five-minute presentation to give over to your Partner interviewer.

Make sure you understand what is in your presentation as you will be asked questions at the end. You are allowed to take a handout for the interviewer, but you will not have access to any IT equipment.

Topics will depend on the area you are applying to, but include:

• Your take on European audit reforms
• Have corporations learnt from the recession
• Regulatory impact on businesses
• How will audit have to adapt going forward

Read more tips about how to give a presentation on our presentations pages .

Deloitte Interview Questions

The variety of interviews and range of interviewers at Deloitte mean that there are many questions you may experience. Questions at interviews may be situational, behavioural, about you or your choices.

Below is a selection of questions that may span any number of interviews:

• Why Deloitte, and why this job/ department?
• Tell me about a time you achieved your goals, and how you went about doing it.
• What challenges are Deloitte currently facing?
• Tell me about a recent news item that has interested you, and why.
• Tell about a recent project in detail.
• What could you contribute to Deloitte?
• Tell me about one of our clients.

For more information about common interview questions and how to approach them, read our free guide to interviews .

Deloitte Interview Preparation

There are several stages to your Deloitte interview preparation.

Start by reviewing your application form and refreshing your memory on what you said about yourself. Expand examples from your form, or think of more examples from your experience to answer similar questions in the interview.

Review Deloitte’s competencies , and prepare examples where you have demonstrated those competencies. Think about answers to some of the more obvious interview questions.

Next, read up about Deloitte from the website and also any news or trade press articles you can find about the company. Think commercially when preparing, and about the implications of what you are reading for Deloitte.

Rehearse giving over your answers so that you can get the experience of saying the answers out loud. You can do this in front of a mirror, or with a friend, but a mock interview is an even better way to prepare.

Our interview preparation package  is a great way to prepare for your interview with a trained assessor who can give you pointers on your performance, and tips for improving in your real interview.

Deloitte Group Exercise

Applicants for consultancy positions in the BrightStart and graduate scheme are invited to a group exercise at the same time as the first interview. Professional hire applicants may also be invited to take part in an exercise at some point in the recruitment process.

In this exercise, you are given a group brief and 5 minutes to read through it on your own. After the five minutes are up, your group has 20 minutes to discuss the topic as a group, and come up with a conclusion. The individual briefs will all be different with each group member required to put forward a case for something else.

This means that you have to take part and contribute fully to the group. Your group is allowed to choose just one option, so you need to be prepared to listen to the others and evaluate whether another option is better. The group exercise is designed to have you working as a team, so your role is to be an effective team member.

Prepare your group exercise strategy in advance and think about approaches for making sure your perspective is put forward without taking over the entire conversation. Also, think about how to deal with others who want to talk and not listen. Get more tips for your group exercise with JobTestPrep.

Deloitte Case Study

The case study is one of the most demanding tests you will have to take during Deloitte's assessment centre. The test comprises an abundance of fictitious documents depicting a company facing business decisions. You will need to analyse the case in hand and devise a recommended plan of action.

You are then asked to give a brief written report or make a short presentation of your recommendations. The key to success in this test is working fast through the documents, prioritising and identifying the key issues.

How to prepare for this exercise?

JobTestPrep's new case study practice pack is designed to help you prepare for any case study. Featuring two full case study exercises, a study guide and scoring tips, this pack will give you all the preparation you need for your Deloitte's case study exercise.  Find out more here .

Deloitte's E-tray exercise characteristics

Deloitte's e-tray exercise is designed to assess a multitude of skills among which are decision-making, planning and organising, problem-solving and managerial abilities.

In the exercise, you are given details about a job description that usually includes some managerial responsibilities. You are then introduced to a simulated online workplace environment including an email inbox, word documents and presentations.

After reviewing an excessive amount of information regarding your position, you will be asked to answer emails, analyse data and address matters of pressing importance. While most questions will be in multiple-choice format, the final questions will require your written response on the following topics:

• Prepare an email communication on a particular issue you were presented with during the exercise. It will normally be an issue you may come across on the job. 
• Advise what would be the most efficient and appropriate way to deal with a series of emails that appear in your inbox.

As part of these written responses, you will be asked to explain the course of action you have chosen and discuss the factors that have led you to the proposed resolution.

How to practice for this exercise?

JobTestPrep offers an extensive online practice pack that follows the same concepts and question types that appear in Deloitte's e-tray exercise. You get immediate online access to two smart practice sessions that simulate similar job descriptions and tasks given in a real e-tray test.

Each test includes a score report, comprehensive explanations to questions and solving tips for performing better on the real test.

Practice with experts

Using case interview examples is a key part of your interview preparation, but it isn’t enough.

At some point you’ll want to practise with friends or family who can give some useful feedback. However, if you really want the best possible preparation for your case interview, you'll also want to work with ex-consultants who have experience running interviews at McKinsey, Bain, BCG, etc.

If you know anyone who fits that description, fantastic! But for most of us, it's tough to find the right connections to make this happen. And it might also be difficult to practice multiple hours with that person unless you know them really well.

Here's the good news. We've already made the connections for you. We’ve created a coaching service where you can do mock case interviews 1-on-1 with ex-interviewers from MBB firms . Start scheduling sessions today!
