I had a group interview with two interviewers: the bogie business manager and the bogie mechanical engineer. The business manager walked me from the lobby to his office and the entire time it was pretty relaxed. Of course I was nervous-- so much that I stumbled on answering one of his questions-- but the manager told me to relax in a comforting way. They mainly asked questions about myself, what I've done, why I want to work for them, and about their company. They didn't expect me to know much technical information. Although I didn't get the internship, I received a call from the engineer who interviewed me saying that I was a runner up... the only one-up the other guy had on me was welding experience. [Edit] I got a call 3 months later and was offered the same position.
