Being in the area, I was brought in for an initial interview rather than having a phone interview. The overall process was relatively quick for such a selective program. The interview process consists of an initial interview whether that be on the phone or in person, and then an intensive second interview that has both individual and group aspects. In the second interview you have to give a presentation about yourself. That is followed by several rounds of back to back 30 minute interviews that focus primarily on behavioral questions. Finally you end with a group exercise that is unlike most interviews I have experienced. Though intimidating I found all of the interviewers to be very kind, and the overall experience was very positive whether you were to make it or not. They flew in people from all over the country for interview.
