Two rounds of interviews; I did not do campus interviews so my first round consisted of two phone case interviews back to back 30 minutes each. One interviewer was a consultant and the other a senior associate consultant. The second round I was flown to their office and had two 40 minute interviews with partners. These consisted of a case with the remaining time left for behavioral questions, about 20-30 for case 10-20 for behavioral is how mine ended up. I applied online early September (shot in the dark, amazing I know - there is hope!) received first round interview at the end of September, interviewed on a Friday, received a second (final) round offer Monday scheduled for a week later (Monday) - was given very short turnaround (told Thursday night I was interviewing Monday morning). Was told the following Monday (one week) of my decision but I know others who received a rejection the Thursday before (3 days after final round). Overall, really great experience. Tip: If you are in the military reserves don't mention it or put it on your resume - I believe they work weekends which would quickly weed you out despite being illegal.
