I feel the same way about little puzzles that companies like to present to the candidates, especially the ones with a "trick" answer.
I never worked in a place where I had to solve tons of small little puzzles all day, or have to memorize a set of obscure language features, and can't look them up online if I need to.
As you said, the best interviews are the ones by a white-board, working together to solve something resembling a real problem. Because, eventually that is what I will end up doing if I work there.
