My main objective at an interview is to see if I am willing and able to fill the position.
I no longer see it as an employer interviewing me. I know some of you managers might take exception to that, but its just the way I am. I've turned down several jobs because I felt I wasn't the right fit, or I had no interest in it.

Did an interview about 18 months back where the 2 idiots interviewing me couldn't even phrase proper questions..and they were the existing DBA and Lead Dev. I couldn't run form that interview fast enough..
