Pros
Opportunity is everywhere at amazon. Joining straight after college, it really molded me into a hard working professional. It helps you identify the type of manager you want to become and gives you insight on how a political corporate american company works. It gives you an experience you will not have working anywhere else. It is an intense work environment and forces you to adapt quickly. Success at this company is a mixture of luck, hard work and political talent. Pay is good and stock options are more plentiful the longer you work there.
Cons
Being a manager that has worked here for 4 years I have seen enough managers leave that I have honestly lost count. It is not for the weak of heart. It is very political in a sense that you need to please all parties involved to get promoted. You quickly see your entire management team get replaced with new managers and overtime you gain so much knowledge that you know more than you boss and bosses boss and even your bosses bosses boss. You work 50-60 hour weeks and get paid for 40. You work 80+ hour weeks during peak. As an area manager you have the hardest job in the building and get micromanaged more than you would imagine. People make decisions without asking you and causes frustration. When working on projects there is red tape everywhere. It causes a self fulfilling legacy due to yearly being ranked against your peers which in turn directly reflects on your pay check. You can work months upon months breaking records and "holding down the fort" and not get a thank you.
