Pros
Being able to work in the fast paced environment of online business. Highly talented people around. Can improve your analytical skill. The business is all about analyzing numbers whether it is pricing, inventory management, or business process re-engineering. Many people who left also agrees that they have learned a lot working for Amazon.com. The skills acquired at amazon is very useful for working in another companies. The business model of Amazon and how you analyze business can be applied to any other online company. Many who left were successful getting higher salary and higher job title. I am also one of them.
Kontras
People are not compensated as well as other top companies. If they had paid well, retention would be higher. There are many people who wanted to work for Amazon and did not negotiate its salary when joining as they should. Many of them assumed that if they performed well, it would be compensated with raise. However, the raise is very small. The company started to give more RSUs which is a good sign. Even with these changes, RSU and cash bonus are not as competitive as other online companies. Another is, if you are not used to fast paced environment, you will feel left out.
