First a math test, impossible to finish but I made it through. Then a phone case interview with an analyst, she was very nice and helpful, gave great feedback. The first case was a simple profit loss case. Then another phone interview with a partner, he was also quite nice and helpful. A little slow to get back to me, but eventually he did. Took them a few weeks to get back to me to schedule the final round in-office interview. All expenses paid. Went up to NYC, had 3 case interviews and 1 behavioral, all 1:1. The interviewers were alright, I wasn't very impressed but didn't have a big problem with them. One walked out of the interview at one point "for a second" and didn't return for 5 minutes, which was frustrating. Another came off as fairly un-intelligent. What ticked me off was that they called me literally 10 minutes after I left the office to give me a rejection... I was in a cab trying to catch my flight... and provided no feedback except "you know, the competition." What did they expect putting a college senior up against an MBA, an investment banker, and someone with consulting experience?
