My experience is that the
least interesting work of my entire career happened during my times at FAANG corps. They have too many overqualified people and too little difficult work to do, so more than anything you just end up playing code games, and "showing impact" by convincing people to adopt new restrictive policies and whatnot.
If you want real tough, new, interesting work, join a startup or a non-tech company where you can have true impact. Alas the pay will be shit in comparison, that's the tradeoff.
Better, start your own startup. These days anyone who can build a weekend demo and talk coherently for 45 minutes to an investor can raise a few million. Not even throwing shade or joking, it's a literal free money fiesta right now, at least until interest rates go nonzero (which will be soon).
