I applied at a job fair at my school and got a call from them a few weeks afterward asking if I'd like to do a quick phone interview. I agreed and set it up. I'm a sophomore, for an idea of where I'm at.
The first phone interview was very easy. They were all behavioral questions with one very general technical one, likely just to do some basic screening.
After that, they called me telling me they'd like for me to come down to Richmond and do an on-site interview. The put me up in a pretty nice hotel right near their headquarters. The on-site interview was a series of three 1:1 interviews. They asked quite a few behavioral questions with a few somewhat general technical questions.
