First round interview was in Boston; two 45-minute interviews - one with a Consultant, and one with a Project Leader. Both interviews had a similar format - a little bit of chit chat, a couple of more formal fit questions, and then the case. The cases were reasonably tricky, requiring a structured approach and also some logic/insight. Moved on to a final round interview in New York. Nearly identical format, but this time with Principals/Partners. Fit questions were a bit less formal (no "tell me about a time when..." questions), and one of the cases was quite unconventional. I felt that the interview went pretty well, but got a rejection call a few days later. Main feedback point was that I didn't do a good enough job of highlighting why I was interested in consulting. I was disappointed by the outcome, but left with a very positive impression of the firm.
