I met with the recruiter first who gave me a tour of the campus then was put into an uncomfortably warm room and spent an hour with several pairs of people. They would tag team questions and some were very probing with their questions and seemed to care about finding the right fit while others just wanted you to jump through technical hoops. One of the engineers, in particular, had a pretty negative attitude and had this strange habit of saying "no, I expected this answer" and then stating something very similar to my answer as though he wasn't really listening. That bit was frustrating but most of the interviews were pretty straightforward. If you've been working on large AAA projects recently then there was no gotcha questions.
