It depends on how it came off. If it sounded like you were talking slowly as a way of talking down to them, I probably wouldn't want to work with you either. A lot of developers can come off as demeaning, and this can be compounded by insecurity by the interviewers (if they think you're a better developer then they'll be more sensitive to you being uppity). Otherwise, it could just be that you seemed like you were too slow moving for a fast paced environment. If I pop my head into your door and say "Hey, how do you feel about XYZ?" (looking for a one or two word answer) and you take 10 minutes to answer, that's not ideal.
