Bear in mind that everyone here on HN is here because they're interested to learn about advancements in technology (and matters of broader interest) - it's too easy to mistake this little echo chamber for the entirety of the talent market.

I often read people say they'd be "insulted" if asked to do fizz-buzz, or would "walk out". I think that's an over-reaction - fair enough they need to make sure you're not useless and lying on your CV. As long as there's a more interesting follow-up question, I don't see the harm.
