Nothing wrong with that in principle, I just can't imagine it. I've never worked at FAANGs, but I have at some pretty closely adjacent outfits (swarming with ex-FAANGs) and 3-4yr is just about the most I can stand before I have to quit (or get myself fired) for a while and reset. Whenever push comes to shove between the medieval politicking and just.. engineering fact, I just can't bring myself to throw what I know to be true and accurate under the wheels of petty nonsense. Surely there must be some middle ground, where companies can grow beyond O(100) people and not lose the plot entirely?
