I had a strange interview experience - the first interview was very straightforward, coding/algorithms questions. I really clicked with the interviewer, he asked me what my favorite course was was and it turned out he used to teach a version of that course - I'm sure that didn't hurt. The second interview was a videoconference with the leader of the team that I ended up getting placed on - he mostly told me about the project and really didn't ask me much of anything at all. I'm really not sure how they decided I was qualified for the position.
