Backstabbing management culture. Amazon keeps the salary low and compensates with stocks which can be beneficial when stocks go up. However a lower salary also impacts the employment contribution to your 401k.
Employees are owners at Amazon. How do many teams, with individual responsibilities and goals, all "row in the same direction"? We have a very common interest and are all rewarded as the company is successful.
Cons
Amazon hires the best, and this is a high-performance culture. The pace and depth expected may be uncomfortable for some.
