I once was given a phone interview because a friend of mine knew the hiring manager. The manager really didn't want to waste time with me, he said, because I had just graduated from school, and thus I couldn't possibly be useful to him.

But at my friend's insisting, he gave me the interview, and summarily dismissed me.

A few weeks later the manager was fired from the company for some sort of unprofessional behavior, and replaced by someone who had just graduated from school.
