The interview was done by 4 people, in 2 parts each with 2 people. The interview took about 45 minutes each, and consisted of behavior type questions and going over my resume. None of the interviewers were intimidating and did a good job of making me feel welcome. They started by going over my resume (something I was obviously comfortable with), then moved on to the behavior questions. They mentioned that if I couldn't think of an answer I could come back to it, and took notes on my responses.
