Pros
Amazon hires some of the most motivates, talented people I have ever work with. Everyone seems to care and the weak tend to leave the company pretty quickly. The signing bonus and stock options are good but only for the first four years. Company is growing so lots of career opportunities.
Cons
Company has almost zero programs for talent or management development. Amazon will sell the company as a start-up but they only mean this by the number of hours you will work (at least 60 each week). There is no effort given to any sort of work/life balance and management is very dismissive of this. If you complain, you are not Amazonian. Management will require an obscene amount of reporting and spend ungodly amounts of time to wordsmith every word in all your documents. Everything you do must have a metric wrapped around it. If you cannot report on it then why bother doing it? Seems that there is no real risk taking here anymore with new business ideas being copied from other businesses. People are randomly fired, moved, or promoted and no one is notified. Highly secretive management leads to distrust of superiors.
