Just to complicate things, "best people" also means "best fit for an organization's culture." I know several HIGH FUNCTIONING engineers from Amazon who went on to startups and failed miserably. But then again, I know several HIGH FUNCTIONING engineers from Amazon who founded startups and did pretty well. But my point still holds... just 'cause you're doing well in one organization doesn't mean you'll do well in a different organization.

One of the best games programmers I know went to [[very large video game company]], but didn't do well. They then went to [[different very large video game company]] and knocked it out of the park.
