Pros
Always Day One !! Great organization, Amazing colleagues ! There is plenty to learn every day & I am saying this with 20+ plus experience already under my belt. The leadership team is absolutely inspiring. You are empowered to make key decisions. There are a number of communities who can help you with various things you are interested. eg AWS Certification , Beta testing of products and devices. One of the striking feature is super flexibility around "Internal Movement" within various Amazon organization and across various geographies. You can create your own path based on your career aspirations. You can actually spend your whole life in Amazon and still do new and interesting work by switching teams every few years. Five Star !!
Cons
Perks are not much different to any other organization. Pension match is 1:1 and employer doesn't contribute double the share.
