alt Hacker NewsMeh .. I've played that game; it doesn't work out well for anyone involved.
I optimize my answers for the companies I want to work for, and get rejected by the ones I don't. The hardest part of that strategy is coming to terms with the idea that I constantly get rejected by people that I think are mostly <derogatory_words_here>, but I've developed thick skin over the years.
I'd much rather spend a year unemployed (and do a ton of painful interviews) and find a company who's values align with mine, than work for a year on a team I disagree with constantly and quit out of frustration.
The company's values may align to yours, even though they reject you. It's because the interview process doesn't need to have anything to do with their real-world process. Their engineers probe you for the same "best practices" that they themselves were constantly probed for in their own interviews. Interviewing is its very own skill that doesn't necessarily translate into real-life performance.
