Pros
Lot of exciting work goes on at Amazon. Good opportunities are there but you have to be lucky to be given them. Salary is acceptable.
Cons
The Stock Bonus and 401k match are a way to keep you around longer since you barely get anything without sticking around for 3years, but most don't stay that long. Too many people leaving and new people coming in, a lot of time and money is wasted due to this. Chaotic workplace. The review process is one which Microsoft scrapped, and is one of the reasons most leave. Very few truly happy software engineers here. Everyone works crazy hours. Some start little later, work through lunch meetings, and till 12 and 1am at night and on weekends quite regularly. No one asks you to do it, but everyone does it so it becomes "normal". So you work super long hours and you don't even get benefits like free food or snacks even. Work-Life balance is non-existent, be ready to bid adieu to your social life completely if you want to stick around. Amazon knows how to convert exciting work into life sucking torturous work which takes a toll on your health and happiness.
