I've hired a few people in IT. Usually you get 100 resumes for a position, then I select the 10-20 CV's/Resumes I like the best. Then I give those 10-20 people a test of basic concepts. You can get rid of the people then that have no f***'ing clue and not waste you time on them. If they pass the test they get an interview.
Too many people have read an article on /. about some technology, or tried something out for day then put it on their CV like they are an expert.
Some people say that's what on the job training is for, but when I hire somebody, I want them to come in and hit the ground running.
