First interview was a one-on-one interview with lots of behavioral questions. "What would you do in this situation?" The second interview was a "superday" where you went down to the main office with all of the other candidates, sat in a room with them for a few hours, and were pulled out for two short half-hour interviews. After everyone was done, you had a team project with a few other people that were interviewing while some of the recruiters/management were watching.
