LOL - "What's broken with *nix, and how would you fix it?". Too bad they gave far too little space for what I would have put as the answer. 🙂
Edit: Question number 10 is interesting, is it simply zero, or is that actually a complex but solvable engineering problem? Time to dust off the EE and calc books I guess.
I'm also quite curious how this test is applied, I have a feeling that part of the "answer" is not simply what you write down, but what they observe you doing while attempting to solve/answer some of these questions.
