I've had the same thing happened to me, were the interviewer was asking arbitrary and sometimes very general questions without much care to discuss anything, which looked quite strange to me. He didn't want to be there, that was my impression.

I believe the reason is that he/they don't really want to hire, they just have to do the interview for some reason. It's this kind of company were the job ad stays up for like 6 months straight, it becomes obvious at some point that they don't want to hire anyone.
