Are the cases available for free.

Almost all resources on PrepLounge (that includes the case studies) can be used with freemium access which means that you get to try it to a certain degree but have to upgrade to Premium to use it to the full extent. However, you have free and unlimited access to the cases included in the free Basic Membership.

What kind of cases can I access in the Case Library?

Our selection of case studies mirrors the wide variety of real case interviews . Thus, you can solve challenging problems around market sizing, market entry, pricing, or operations strategy. Moreover, all provided cases are marked with a level of difficulty and the respective case style. This will allow you to filter for interviewer-led (as used by McKinsey) and candidate-led cases. In addition, some of our corporate partners granted some great original cases that have been used in real interviews.

How many cases should I have practiced before I show up for my case interview?

There is no set number of cases you should solve before your interview. However, you will find that the more practice you get and the more different scenarios you tackle, the more confident you will become in dealing with case prompts. Also, in addition to self-study, we recommend that you act out real interview situations. Just choose from over 370,000 candidates and practice cases from the case library together.

Who can I contact if I have problems solving a case?

Next to each case you will find a button that allows you to post a question directly to the case in our Consulting Forum . Our experts will answer you as soon as possible and support you with your problem. You can also contact the experts directly.

I worked hard for my offers and the investment in the course paid off.

It has been a massive mindset shift and I became a big fan of the hands-on approaches taught in the sections. They do an excellent job of converting difficult problems for frameworks, charts and math into simple manageable tasks. This had 4 big impacts on my performance:

1 - I can create more exhaustive and targeted case frameworks in the same time or slightly less time than before 2 - I only need 20 seconds to analyze a chart thoroughly 3 - I have a more structured approach to math problems and calculate faster. I still have to work on getting the formulas right sometimes 4 - I feel more confident in the process

Succinct and useful guide

Coming from a nontraditional background I was frustrated with the confusing information on McKinsey interviews. Even McKinsey fails to explain how their interviews work - it is all very vague stuff like "we want to see your authentic self". What does that even mean?

I found help with this academy with tremendous content about the two parts of the interview with simulations and detailed feedback / explanations. Every aspect is broken down clearly and my doubts were indeed erased. Because of this a great amount of insights and tactical advice I can't recommend the content enough.

I would appreciate it if more practice were included.

Florian provided advanced-level feedback on my PEI stories and besides had very valuable tips to engage with my interviewer and build a connection.

Productive and illuminating meeting.

Very professional package that provided a lot of insights and structure in preparing for case interviews by outlining the tasks and strategic ways to tackle them. The courses and practice are clear and straightforward, translating how your performance is scored and what is necessary for improvement.

The large library of high-quality practice cases and drills was a huge help since I couldn't find similar cases before, only standard ones and with bad explanations and design. I used it alone but also with a study partner and it was fun grilling him with questions.

yields broad insights into many areas, lacking some depth but I am unsure if this is required for the sake of interviews.

This suite of products is extensive and Ive experienced many improvements in my cases. It helps you with learning and practice plans, courses on frameworking, charts, mental math and, most importantly, helps you practice with good materials. Doing these drills instead of relying on cases from books made a world of difference. The quality is just so much better.

Florian's 1% coaching package stands out due to his dedication and personalised attention. The time and commitment in each session surpassed my expectations with all meetings going way past the scheduled time. His support extends beyond sessions and I found myself bombarding him with questions to which he responded quickly and with patience.

He is a pragmatic coach and concentrates on strategies and critical thinking rather than memorization of frameworks. This approach and his mindset tricks have given me a sense of security and versatility for a diverse range of cases. Moreover, Florian's provides a preparation plan, complemented by targeted practice exercises and the opportunity to connect with like-minded coachees in his network.

Having worked with other coaches in the past for internship interviews, I can assert that Florian's approach and feedback, coupled with his vast experience across different firms, and his engagement is rare. I have not experienced this before.

I got everything out of the programme I wanted.

The case interview preparation package is very well crafted. It offers a deep dive into the nuances of the case interview parts and breaks them down into comprehensible steps. The drills closely mirror real scenarios and include a self-evaluation mechanism to help improve your approach. They feature a feedback loop helping you become better and understand why certain solutions work. This package is dense but a must have for anyone serious about nailing their case interviews.

The missing puzzle piece for me. It's easy to find cases for frameworks and math but I found that when it comes to charts in consulting club case books and paid platforms like preplounge or rocketblocks they are unrealistic and too simplistic.

Great interviewer and coach.

We had our first introduction call and I felt that he fully understood my background and aspirations. I booked a session and was not disappointed:

I was somewhat at an intermediate stage with my casing with little time left before my first round and I was not sure if a coach can add value. I was fine with math but struggled with structuring. He used a case in an industry that I requested and immediately identified what I needed to change to become 'distinctive' in the interviewers eyes. In the feedback he guided me through the case and told me what I needed to do or where I had to change my approach. He went over a few big levers I needed to implement and many micro habits as he calls it and showed me how these changes would impact the score sheet. We ended the session by discussing practice tips and drills to work on these areas.

Passed the first round and will book one or two more before my final round.

Florian analyses your case skills in-depth in the first session and shows you how to improve in the different dimensions to meet the standards set out by the top consulting firms. The feedback is very organised into different skill dimensions and case elements and extremely detailed. I really liked his hands-on approach and down to earth coaching style. I constantly had the feeling he was working with me throughout the whole process even outside of sessions when he answered all my questions. He gave me practical guidance on negotiating my entry.

After my McKinseys interview today I received the feedback that my case structuring was "outstanding" and I attribute much of this success to this course. When I started cases, frameworks confused me. I struggled with understanding what to include, what to leave out, and how in-depth my analysis should be. Going through this course I had a breakthrough as the process was broken down in simple steps and terms. For the first time I understood what role the framework serves and how to narrow or widen my analytical lense based on the case objective. It all made sense. Following this insight, I diligently practiced with the exercises provided, leading to the positive feedback I received today.

The handbook helped me structure my thoughts on a couple of topics and industries I was unaware of.

Offers a clear and detailed analysis of the PSG. It presents a good overview of each game but also pushes you to actively think about each game's hurdles. Working with the Excel solver has helped me a great deal.

Florian is a great pleasure to work with, my CV has gone through multiple itirations by many industry professionals and coaches from PrepLounge. But he still managed to futher fine tune mine and was always quick to respond with an amazing turnaround speed.

I highly recommend this to anyone who is preparing for consulting interviews. It's a well designed prep program that covers not only the theory for each element of the case and variations but also all essential practice materials for creating MECE issue trees, analyzing charts from interviewers and cracking case math problems. Florian's offer to help with questions and case problems at all times adds significant value to the overall experience.

It gave me confidence because it lays out a plan. It is still a challenge but I don't think its possible to pass if you don't know how to tackle the stages in the short time you got without a Excel model to organize your thoughts and do the computations and checks for you. Both parts of my game were as expected. Thanks for the help.

I was about to apply for a MCKinsey internship when I found this course. I think it is very well made and provides a full coverage of the assessment. The Excel solver tool was easy to work with and does the trick. I would buy it again.
