I've been on both sides of the interview process--more on the hiring side recently. The most important factor is to be able to show awareness of the other people in the room. For example, do you notice when you are boring people? When your answer has gone on too long? Are you just reeling off a spiel about your research or engaging in a conversation? If the interview lasts 30 minutes, what does giving a 10-minute answer to a question do for you? It takes up a third of the time and shows you to be a self-absorbed person. You need to answer informatively and briefly, and then take follow-up questions.
Don't suck up to the full professors in the hotel suite and ignore the junior faculty. Even the full professors will hold that against you. One job candidate once looked at me and said, 'You and [name of other full professor in the room] are so productive." The other professor quickly mentioned that the other two people in the room, more junior, were also publishing scholars. It was a very awkward moment for all concerned.
