Peter Norvig mentions a fascinating discovery made at Google:

One of the interesting things we found, when trying to predict how well somebody we've hired is going to perform when we evaluate them a year or two later, is one of the best indicators of success within the company was getting the worst possible score on one of your interviews. We rank people from one to four, and if you got a one on one of your interviews, that was a really good indicator of success.

Something very interesting is going on here…
