It's a truly horrible place to work and I would never ask my worst enemy to go work there. Engenders the worst in humanity (people review, anyone?), terrible technical architecture, many systems based solely on tribal knowledge that leaves the door every day, comp structure that is nearly outright lying... I could go on.
Some people say that it was just the group I worked in but I worked in retail (1 year), new businesses (1 year) and AWS (1.5 years). There's virtually no difference. I still have PTSD (or at least what feels like PTSD) about by 3.5 years there, and I'd give anything to get that time back.
BTW, I'm now at another 20k+ person company which is doing very well, and making 30% more than my total comp when I was there.
