My first interview consisted of a random group of people (who I would not wind up working with) asking me specific technical questions that had nothing at all to do with the job. By the end of the interview, the group admitted that none of them knew what kind of position I was applying for. This didn't seem to bother them, particularly. My second interview consisted of several sessions, two with people who would be reporting to me in the position. These two were basically complaint sessions where I just listened to them talk about everything they disliked about their job and the company. Another session was with a random employee who asked me generic "how do you work with people" questions and seemed fairly unpleasant.
