For the first half, I talked to someone in a similar position; in the second half, the interviewer was my potential supervisor for the job. We were required to prepare a presentation about ourselves for the second half. The questions asked emphasized my past experiences (e.g. explain this about this past job you had).

I had a two part interview. First with the previous intern, which included many generic interview questions. Second with the division manager. I had to make a short presentation about something that I had previously done. The whole interview was more like a conversion than anything else. It took 45 minutes with a lot of waiting time here and there.
