I only ever do ask one question in an inverview. I decsribe a simple application and then ask the candidate to design the database schema and business objects to support it. That usually takes up the time I'm given with the candidate, and tells me a ton about what techniques and technologies they've been exposed to and their maturity level working with same. I also watch for how willing they are to involve me in the process. The best team candidates have me working along side them (but then I get to toss in a few curve balls)
