Pros
The company is still growing strong. The core retail business is taking share in this economic down term. The Amazon web service is picking up and well positioned to compete in cloud-computing. The Kindle is catching the attention.
Cons
The company cares about customers, but doesn't care about its employees. A customer can easily send an email to Jeff Bezos for a very small issue, and the employees will be busy working several days just to explain to Bezos. Management rarely shows respect to employees' life. One senior VP was heard saying that he doesn't believe that there is employee morale. The company is religious about data, but not all managers are good at specifying what they want when they ask their subordinates to produce the analysis, and often change directions, which results in a waste of everybody's time. The company is very cheap, and you will understand it when you see the office and the benefits.
