Pros
Amazon is a place were you work next to really smart people who are motivated and excited about what they do for a living. While our workforce has changed over the years, the culture instills a focus on knowing the details of your business, maniacal focus on the customer - even if that means short term and perhaps long term pain - because that is the right thing to do and a willingness to take risks. People who love change and deal well with ambiguity thrive at Amazon. Those who want to be told what to do and who desire a clear road map get very frustrated. Every job has it's ups and down and Amazon has had it's fair share and more, but the company continues to innovate, continues to eschew the trappings of success and the employees take pride in their work.
Cons
Promotions are few and far between. Stock is a big part of your compensation and because our stock swings wildly it can significantly impact your income from year to year. For a new person Amazon can be quite a struggle to find your place. Most groups are sink or swim and if you are hired you are expected to seek help as it won't seek you.
