Beyond the fact that the person you interviewed is a complete (seemingly) moron for trying to pass himself off as a Un*x veteran, since you mentioned that you are interviewing people for a position, how many emails have you received offering to fill said position? Given how things are, I would *assume* that many of us looking for a position (who seem to know more than the nameless subject) would be more than happy to attempt to fill that position.
lol - that just struck me as funny in this time of so many computer people (highly qualified people) who can not get a position because of too much experience. Does your human resources department filter your prospects for you like most companies?
