I've never in my life had to implement a recursive memory optimized underwater red black tree balancing algorithm, and it's insulting to be told I'm not a good enough programmer if I can't pass your totally contrived white board problem. Who the hell are these people even selecting for with these kinds of questions? Do they understand how much talent they're throwing away?
In any case, I have a strong suspicion that, aside from compensation, working for FAANG is hugely overrated. And that's not just sour grapes talk - mountains of red tape, processes upon processes, overwork and burnout, and best of all, you get to spend your best years infecting society with the cancer that is adtech.
