My initial interview was after a summer internship. It was a single interview that consisted of three employees. One employee was my champion and was there to reduce nervousness. Basically, I already knew him from my internship. He did not ask any technical questions, but was my fit interviewer/advocate. The technical interview lasted about two hours and mainly consisted of standard algorithm questions, data structure questions, and some high-level questions regarding computer architecture.

I can't remember all of the questions, but at the time, I think the reverse the linked list question was nerve-wracking, just because I made a mistake and got frustrated.
