Pros
Amazon keeps making bold moves and placing big bets, and while it may appear to be a sophisticated company that is laying waste to competitors on the outside, the culture is self-critical and constantly looking for new ways to invent and deliver new and delightful services to our customers. If you work for an influential technology department at Amazon, it is a fantastic place to learn what it means to launch a business from the ground up - from the inception of an idea to getting a public launch across the finish line.
Cons
Performance reviews are less about your actual contribution at the workplace than they are about managerial opinions about your leadership skills and growth potential. Most review assessments take place before an employee assesses their own goals and although you may have agreed upon your goals with your manager for the year, they may not contribute much to your overall performance review for the year. The review assessment seems more based on judgement rather than measured contribution.
