Depends on which letter of the FAANG pantheon you are in, but my understanding is that it is much harder (and arguably more prestigious) to get into some of the FAANG companies than most PhDs programs.

Personally, if I were in your shoes, I wouldn't bother with a PhD unless we are talking about something MIT level.

Also, I don't know your personal situation and capabilities of course. But all of my friends & colleagues at FAANG level companies swear that they would not be able to pass the coding interviews again if they had to redo it, and even if they could, it would only be after many, many months of hardcore grinding (leetcode, etc) that they'd rather not do again.
