The criticism misses the point of these tests, no one cares if you can reverse a b-tree or not. It's meant to serve as proxy for a good candidate, one that can reverse a b-tree is expected to have more coding chops than someone that can't.
Whether they're good or bad proxies is certainly debatable, but at least that's asking the right question.
- craftinator 8y agoI can derive a b-tree reversal on a whiteboard in a Faraday cage given a few hours and a pot of coffee. I can memorize someone else's reversal solution in maybe half an hour. The first method tests my ability to logically break down a problem and find an elegant solution. The second tests my ability to memorize shit. Candidates don't have a chance to do the first during any interview I've ever heard of; so logically you'll be hiring those of the second variety. Good luck with that.
- BubRoss 8y agoI don't think anyone is missing the point that an interview can't literally be exactly what the job entails.
