It seems like many employers are quite worried about hiring someone who is under qualified, even though they can legally fire them for any (for certain values of any) or no reason where I live. Given that, it doesn't seem like the worse problem in the world to hire someone who is over qualified, and if they get real unhappy, they give a professional 2-weeks notice and then leave. I think we're all probably ignoring the real reason this happens though, those hiring are intimidated by the over qualified candidate. "A's hire A's and B's hire C's" as they say.
