> Everyone says ... a true engineer's paradise.
I've never had this impression of FAANG. I always figured there were a tiny number of people working on amazing projects, surrounded by a much larger number of people keeping the lights on, or working on very periphery projects that either no one cares about or which will never ship because of politics or business whims. Did you really think it would be ... paradise? Thinking that about ANYTHING is a recipe for dire soul-crushing disappointment.
