Our entry test should have been dead simple for anyone applying to the position. Position: C++ computer graphics programmer, 1-2 years experience implementing technical graphics displays in C++ language. All resumes submitted, of course, claimed this and more. All interviewees, of course, professed great confidence in their abilities. 9/10 candidates, when presented with "the test" failed spectacularly. The ones who passed, generally, did it in less than 10 minutes - with a couple of interesting quirks which revealed their attention to and/or willingness to follow directions. The failures ranged from rage-quit and stomping out without a word, to hours of pleading for more time to work on it - which, in principle, we granted freely, but after 30 minutes if they didn't have it they never got it.
