I had an on-campus interview at my university and then 2 weeks later, final rounds in their office. The interview was split up into 2 days and they interviewed more than 50 candidates for the final round. I interviewed with a VP and 2 senior consultants. They were great, except my third interviewer who only talked about herself. I had to stop her and even then she only asked me one question. Then, later we had a group case interview.
