I recently interviewed for a position that I thought I'd be a shoe-in for. They liked me enough to check references and conduct a back ground check shortly thereafter. Then...nothing. I heard nothing for about 3 weeks until today, when the committee chair let me know they would not be offering me the position. Would it be kosher of me to ask why, or for some feedback? I'm having a bit of a hard time coming to a conclusion, the only thing I can think of is that a) a reference of mine said something they didn't like or b) they changed their minds about the job description halfway through. I will be working with this person and the group he leads a lot in the future, so I don't want there to be an awkwardness going forward.
