When interviewing a faculty candidate, how should I structure the interview? What questions should I ask? How should I make the best use of the limited time available? Assume this is for a full-time faculty position at a R1 (research-focused) university.
If you have a 30-45 minute slot (which is typical for such things), you have to make some decisions:
In general, since you can't really get a big read on a candidate in a short session, your best bet is to focus one one aspect (such as one of the above), and explore that in detail. One thing I've also found useful is to ask questions "out of left field" that test the assumptions the candidate's work rests on: if done right, this allows you to explore the candidate's larger views about their field and the direction of the research.
