So OpenAI and Anthropic are decacorns that are paying far far more than any FAANG so it's hard to compare them. Meta, Apple, Nvidia, sure, I can understand the sentiment, even if I don't completely agree. You see a lot of people shuffling between Apple and Google so it's probably org/team dependent.
Meta pays the most of FAANGs so they certainly have a lot of talent.
Microsoft is not even close to being on the same level. I did multiple interview loops there and I can't say enough negative things about the company. Every other FAANG company pays more and values talent and intellect higher than microsoft does.
The only employee I met at Microsoft in my interview loops I was impressed by is now...at OpenAI.
