Boston Consulting Group Intern interview questions

From over 500 candidates, 50 were picked to do interviews at the office. There, I had two case rounds with consultants and 1 online case. The online case was slightly more difficult than the one trial case that you can find on their website, also some questions were not that well explained.

2 interviews + 1 online case (multiple choice) online case: you get a virtual case study and have to analyze the company (e.g. calculate revenue, profit margins) and determine what there most critical problems are and how you could tackle them. All questions are multiple choice (exactly 1 solution correct). Half of the people struggled with the time, so be sure that you can do some more complex multiplication in written form very quick.
