I posted this in the embedded C-shop I work, under the comment that exactly in this place all should pass this test. Sadly only 1 in 5 passed the test (yours truly). Admittedly, this test was binary: either you pass or fail all of the questions (which is also sort of a give-away). In the end this test proved to be a really valuable, because the "I don't know" drove the point home, specially for smart folks who don't like to answer any test, ever, with "I don't know".
