The most important lesson in interviewing I've learnt is to shut up. If you're doing the talking you're not learning about the candidate. Say as little as possible, if they ask good followup questions they will figure stuff out (see also above comment about curiosity).

One of my most frustrating interview experiences was when the lead engineer constantly interrupted me in the middle of my answers, clearly looking to get an answer that confirmed his existing opinions, then stopped the interview because we were out of time. He didn’t let me finish answering a single question, then rejected me because my technical knowledge was “too shallow”. I’m glad I never had to work with the guy.
