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.

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.

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.

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.
