This is the first article I've seen which mentions something that should be fairly obvious to interviewers — expecting people to code on whiteboards is a common mistake. As an interviewer, I totally cringe when I imagine filtering out good people this way. (I say that as someone who enjoys interview puzzles, and have always succeeded at them. But that pleasure's probably pathological. For many people, it's a nerve-wracking ritual which pointlessly damages self-esteem. As a gatekeeper, my job is to help them succeed at my silly little games. Assist them in reaching their limits.) A lot of the mind is in one's hands, as many emacs users might tell you. That intelligence can disappear in the alien environment of the whiteboard, for those unused to it. Many bright people maybe can't even afford a decent whiteboard, and haven't worked in an environment which uses them. There's a huge amount of good tips for good people to get past the gatekeepers — and negotiate good terms. If you can not just beat the interview, but kill it, you'll often have a more powerful bargaining position.
