Applied through school's hiring page. First round consisted of two cases, about 20 minutes each. Time at the beginning to go over one experience on my resume and a few questions at the end. Two very friendly interviewers with rather basic cases with a couple of calculations. Was called on the following Monday to schedule second rounds. Second rounds took place in my choice office. Consisted of three interviews, 45-minutes each. Two principals and one partner. About 10 minutes of fit in a mixed fashion. Some "tell me a time you did this..." some explain this part of your resume. Each case was real work in interesting situations. Extremely free-wheeling, so having a good up-front structure was very important. None of them had definitive answers and none felt "aced." Beautiful office, extremely bright and friendly people.
