I had an on-campus pre-interview night, where all of the candidates on the campus were able to speak to each representative/interviewer, which lasted for a couple of hours. The next day was my interview. It was 2 half-hour long interviews, each with two people. All of the interviewers were very nice but seemed to not know anything about my background (I'm an engineering major, so most of my experience on my resume wasn't familiar to them, just sounded impressive I suppose). A week later, I got an email asking me to fly out to Salt Lake to have an in-person interview. I accepted and they paid for flight/hotel/food/taxi, everything. The hotel was very nice and right next to the office, so I was able to walk about 3 minutes to the interview in the morning. However, the interview was exactly the same as the interviews back at home, so I thought it was very wasteful and unnecessary that they flew me out (along with at least 20 other students) for a second interview that was exactly the same (there were different interviewers, but they pretty much asked me the exact same questions and it was the same format). I didn't think the final interviews went very well but I did get an offer.
