Its not over until the fat lady sings

Apparently human resource experts say that the interviewee is not objective about how the interview went. Most think it went worse than it did. Most are very hard on themselves. So don't despair after an interview.

My experience from being on many interview panels is that people are rarely "sunk" from one poor answer. Furthermore, it is the "vibe" that matters not all the specifics.

While on the subject, positive feedback does not necessarily translate into a forthcoming offer. Furthermore, even a verbal (or email) indication of a forthcoming offer is not the same as an official written offer. Sometimes wheels do fall off the wagon....
