I found this article via LinkedIn this morning, and agree with it completely: http://ix.ly/d1xj For the impatient, the three questions are:

1.  Can you do the job?
2.  Will you love the job?
3.  Can we tolerate working with you?

I've never asked these specific questions but feel like they'd open up the right dialogue from the start of the interview. What do you think? What works for you?
