When you see a Meta candidate you know
* They went through one of the hardest interview loops in the industry
* They went through one of the hardest promotion ladders in the industry
* They solve all problems at huge scale out of the box
* If you aren't paying top of market and they're still interested, they're most likely financially comfortable from their years at Meta and won't be jumping ship every 18 months for a 20% raise
I'd say that's pretty attractive as a hiring manager
