Seems like a simple enough question, does it not? You have an open position, you publicize it, sit back and watch the resumes poor in, then pick the person who's best qualified. Simple. Or is it?
Side note: there are countries (like Cyprus) with very small unemployment rate. In places like this you have to actually go out and look for people. Sometimes you even have to import them from other countries, like my current employer does. Interviewing and selecting potential employees become tricky. :)
