Interviewed for a job today and felt I could have done much better. I have a good gig now, so if I don't make the cut it's not the end of the world. Just wish I had thought through the answers a little better. I think the biggest mistake I made was not thinking about WHY a particular question was being asked. At least I didn't do what a former colleague of mine did by ending with, "Oh, and that thing about the sheep? They never proved that."
