Pros
Very supportive of your career path and understanding of the demands outside of work. It is one company who despite the economy downturn, continues to grow and stay positive. The main reason for this is the central focus on the customer, their needs and their interests. Another reason they are so successful is innovation, they are very willing to listen to and incorporate ideas from any of their employees. The "all-hands" meetings, held quarterly, are fun and informative. The management is approachable and are willing to help with any aspect of your position, whether its corporate questions down to the individual task.
Cons
Like more companies Amazon holds a review process over the first few months of the year. It consists of each individual goal setting for the year, writing up a self review, a management review, and three to five peer reviews. The reviews are then processed through an detailed and lengthy review process of their own, where a score is determined after comparing the individual to the company's core values and core competencies. This score determines your raise and also follows you throughout your time. So, if you score low, you will have a tougher time moving up or into new positions. It results is some good feedback, however is extremely time-consuming and can be potentially damaging to your Amazon career.
