Avantages
Amazon.com is a great place to get started in your career. It will teach and challenge you at the same time. Project work can be challenging (5% of the time) The kind of people who work in the company are very smart and will keep you on your toes. The customer centrism is a strong guiding force in the company, and it is reflected in everything the company does.
Inconvénients
Amazon.com has been slowly degrading as a great place to work. It took several years for me to notice, however there it is. Project deadlines are insane (95% of the time). The company's customer centrism works against it as a workplace as company employees are not customers. Your needs come secondarily to the customer. Which means: No perks, no philanthropy, small raises if any, low powered equipment, and a general lack of care by upper management for the operations load generated by rushing projects out the door.
