PrepLounge has a huge repository of cases. Ideally, I'd have liked to go through all of them, however, considering the paucity of time, I want to look at some select cases wherein I can derive the maximum learning from the time invested. Please let me know if anything comes to mind!
What are some must-do cases in the PrepLounge case library?
I can't speak to specific preplounge cases. However, I can share my favourite resources for case interviews while I was going through interviews. You should be able to find all of these online quite easily:
1) Company websites: McKinsey, BCG, Bain, Oliver Wyman, etc. all have excellent examples of cases online. These are excellent as they come straight from the source and are generally a good indication of how cases at a specific company are structured
2) ESADE business school case book: This book provides some excellent tips and then dives into some great beginner/intermediate cases. In the second half of cases in the book there is a drop in quality, but it was still one of my favourite resources when practicing.
3) MIT Sloan 2011 casebook: In my opinion the best case book released by a business school I have seen. Excellent cases of ranging difficulty from actual companies, which most closely resemble actual cases you will receive while interviewing.
Hope this helps!
The case study is the most important element of the case interview, which you'll have to nail in order to get into strategic consulting. Here you can learn the specific skills and concepts necessary to solve them.
Getting Up to Speed

Interviewer-Led vs Candidate-Led cases
Case Interviews can be led by the candidate or by the interviewer: In Candidate-led cases the main challenge is the structure. In Interviewer-led cases the main challenge is to adapt quickly
