Most programmers already know how to win the coding interview. You simply have to solve problems, at the same time trying to evaluate your next boss (or at least the kind of people who work there) by the level of insanity they generate during the interview. If the coding style in the company disagrees from yours too much, it's a good thing they won't hire you, so no problem there.

The tough thing is to pass the HR interview, with dozens of idiotic questions and no way to answer them correctly except having googled the answer to each particular question beforehand.
