Pros
Amazon is a "can do" place. People who are ready to work hard, be courageous, banish self-doubt, and fight can do well. Even for those who find it hard to be aggressive, Amazon will surely benefit you and help you learn new skills. Opportunity is there for the taking, but no one will coddle or encourage you - ever. It's a tough place, but it pays well and gives you lots of opportunity.
Kontras
Encouragement, peace, and calm DO NOT EXIST in this place. It's a go-go-go atmosphere that you can sense by just sitting in the lobby of one of it's buildings and watching the crowds scurry in and out. Everyone is on the go, NOTHING is every good enough, and all employees are pressed to be more, do more, and reach higher. The unrelenting pace and pressure to do more burns most people out within 2 years.
