I went for an interview on Tuesday last week. I felt it went very well, and the feeling I got was that the job was mine. I was told I'd be called in the next few days, which be the time I got to Friday I was concerned.

I'm pretty much resigned to the fact I didn't get the job, but should I call them to find out why they didn't call, maybe they still haven't made a decision, and to get feedback from the interview?
