I think the rationale at the scale of this point in FAANG is to hire as many people as possible and see who can't hack it (pun intended). In the early days, they had to be more choosy about narrowing the talent pipeline with harder interviews. Actually, I remember one IT-style interview 12-ish years ago with a certain FAANG that shall go nameless that had this sorta narcissistic/sorta dumb hiring manager, whose profile picture was a shirtless muscles pool pose, believed that a technology I inherited and was forced to use was an interview deal-breaker. And, at the time, I was at an IT department at Big Name university down the street where there were much more complicated and interesting things going on, like remotely uninfecting and patching worm-laden systems and putting together a fully-redundant/HA VMware cluster that had an FC SAN and blade servers (the thing back then).
