They disguise it very well, but this place is ran like a cult.
Pros
Great benefits, good total compensation and exposure to bleeding edge technology.
Cons
What can I say, working here literally gave me a severe anxiety disorder, I actually had to take therapy after I left to treat it. There is a cutthroat culture deeply ingrained here, you are quietly going to be pitted against your own team whether you like it or not, this is amplified by the fact that the company does stacked ranking during performance reviews, if you don't know what that is, look it up, its terrible and its morale crushing for employees, they are aware of it but are not willing to change it. Managers are semi supportive but will not put their hands to the fire for you, their expectations are ridiculously high and borderline unrealistic especially when they provide very scarce guidance and almost no structure. This the only company I've ever worked for that actively punishes you for your mistakes no matter how small they are, once you get a bad performance review there is no coming back, it will haunt you forever until the day you quit or are laid off. Save yourself some mental sanity, there jobs out there that pay the same if not better and are not as stressful as Meta/Facebook.
