Maybe the companies I've worked for have all been unusually picky about hiring ...Or their initial screening heuristics are unusually bad and have to interview tons of candidates. Or maybe their recruiting process is really good at generating a high volume of sub-par applicants. Rejecting a lot of candidates after subjecting them (and current employees) to grueling interviews doesn't mean they're making good hiring decisions.
