My father-in-law worked there as a programmer during the Cultural Revolution. There were always guards on the other side of the (locked) office door. Sometimes they’d shoot at random things to remind the nerds just who was in charge. When I worked at Microsoft the biggest complaints were parking and the variety of subsidized foods at the cafeteria.
I already grew up in a middle class family, but I had a fellow intern at FB whose father used to smuggle furs into Soviet Russia. I really loved that juxtaposition. Nothing new under the sun, but knowing him personally it hit me more :)
I don't know how exagerated that was, but yes sometimes things go fast:)
