Pros
Great work force from L2-L5 IC's and front line managers.
Cons
AWS invests in infrastructure, not employees. Their safety protocols are shockingly behind industrial standards. They have grown too fast without support the basics and fundamentals. Their training program is an awful concoction of tribal knowledge and outdated wiki pages. If you get permission to do anything, you better get it in writing because management would rather sacrifice you instead of having your back. This environment is ripe to create a situation that will kill someone, literally. Especially considering the severe lack of understanding and guidance that is facilitated and allowed to prosper. Their performance measure system constantly pits people against each other or against standards that are rarely defined beyond vague generalities.
