I applied through campus recruiting website. Then had the interview on campus. It was 2 (30 minutes) interview. The interview was mostly behavioral questions but I believe they looked for really tech savvy or technical people in general. If you can talk about a project you did in class that was highly technical will be very helpful in my opinion. When I interviewed, I only took some basic business classes and therefore I couldn't talk exclusively about tech projects.

I went through three rounds of interviews (2 month process) and all had the same basic format: 30 minute one-on-one interviews with a succession of people in a small conference room. Everyone was nice and engaging.
