I have never worked there and I am likely very unqualified to ever work there and Zuck has more money than I could dream of so take my comment with that in mind.

Meta sounds like a cluster-F of a place to work. Massive reorgs around wild ideas like the metaverse and everything Ai all the time. Employees terrified of being fired. Incentivizing token spending and then cutting it off. While the overall company may be fine, the dev department sounds rudderless and absolutely miserable.
