I've been approached by a couple of FAANG and told them to stuff it because of the recruitment processes. I'm in London, and here at least they're extreme outliers.
If you're early in your career, they probably matter and it might be worth it, but for me it's not.
Maybe it'd be different in Silicon Valley, but in London they just aren't willing to offer enough over and above the kind of jobs I've had elsewhere to be worth the misery (with the big caveat that I'm at the high end of non-FAANG London market rates; for someone who is not, FAANG may be worth it here too)
