It depends on what you are looking for. Many socially awkward "nerds" learn how to socialize outside of just academics when they are in college. If there are few outlets besides just academics, it's hard to become "well rounded" socially. I can tell you I'd rather hire a socially adept but slightly less intelligent person rather than the brilliant but incapable outside of his field person. Unless of course I am hiring a nuclear physicist, etc etc.
