I connected with a recruiter via email after a job fair. I was initially set up for a phone interview, which consisted of 4 questions, three behavioral and one math question. It was pretty straightforward. I don't believe the interviewer knew anything about me, probably didn't even have a copy of my resume. I was then contacted about an on-site interview, in about three weeks. I attended the "on-site interviews," which were actually at a hotel. There were around 15 other candidates. I was interviewed by four different people, each asking behavioral questions, except for one who went over a harder math problem. It was fairly straightforward, but a little nerve-racking. The interviewers ask more questions that drill down to the details of your answers.
