If I'm a FAANG, I'm simply not using my normal interview process to hire for the really interesting jobs. I reserve those ones for people who got the job by virtue of their publication history in the academic literature, or because they built some well-known cool thing, or because they got promoted into the position. Those people get shunted over into the "you didn't come to us, we came to you" interview process.

The seats I'm looking to fill with the more public interview process are mostly seats for the grunt coders who work under those people. My ideal candidate for that position isn't some rock star creative genius; it's a workaholic who is resistant to boredom. And what's something a workaholic who's resistant to boredom would be really good at? Grinding away on programming interview questions, of course.
