I had an on-campus interview with an incredibly kind and enthusiastic interviewer. Basic behavioral questions for around the first 15 mins but then we just started talking about our personal experiences. Really great conversation! Was invited to the second stage which was at the office. 2 individual interviews and one group case study. Both interviews again were just conversations, it seemed that the interviewers were more interested in my life which I didn't mind talking about. Some behavioral questions were asked as well. Cap definitely hires for character and attitude. If you get past the first round, it's now a matter of what kind of person are you and can we work with you. Interact with people, talk to the other applicant (There are many) smile and always be humble.
