I applied through campus recruiting and was selected for an on campus interview. The first interview was conducted with a partner. To my surprise the interview was very laid back and lasted only 30 minutes. We went over my resume for about 10-15 minutes and then talked about the position and the responsibilities involved. About a week later I was invited to participate in the Inside Look (second rounds) program. I was extremely nervous a few days leading up to Inside Look but again, it was very laid back and informing. The first night started with a tour of the office and concluded with a two hour dinner at a very nice steakhouse. The second day lasted from 8am-2pm with various activities and a couple of interviews with senior managers. All of the interviews were very laid back and did not include any behavioral questions. Though a few of the other candidates I spoke with did have behavioral questions. It all depends on who you interview with.
