At Google I'm convinced our interviewing system only works due to a combination of luck, large numbers, and generally good intentions. None of the individual steps is a particularly good way to tell if someone will succeed at Google, but anyone who passes all of these filters is unlikely to be a terrible engineer. When you avoid terrible engineers and hire by the tens of thousands, you get plenty of good engineers and a few great ones. You also miss a ton of qualified candidates, but Google has more of those than it needs. It can afford to miss them in a way that small companies can't.
