The interview was your typical MBB interview, case study was interviewer-led with a project manager. I was asked three question before the case study; why BCG and two of your typical competency questions to show leadership if I remember correctly. The recruiter for the interview was not that organised I would have to say. it took a month to organise the interview because the recruiter was on leave and did not even bother letting me know in advance, so I thought I was ghosted at first. I also asked for feedback and till this day have not been able to successfully arrange for one with the interviewer.
