Pros
Amazonians truly live by their Leadership Principles, if you align with them, you'll find you're a great culture fit. A candid chat meeting is available to you during the interview process, with an amazonian that is not associated with the team you'll be considered for. The amazonian is chosen at random and they do not report any details of the conversation, so you can ask any difficult, blunt questions you want to, in-order to best determine if Amazon is right for you. Onboarding is packed with information. There are tonnes of resources at your disposal. Small teams own a given service or services, which eliminates much of the burocracy of working at a typical large corporate entity, and empowers team members to make meaningful change. There is a lot of freedom of choice, and team members are encouraged to challenge the status-quo to do what's best for the customer / long-term. Most of the tools / services used are internal, so if you need help with using one, or spot an issue, you can reach out to the team that owns it. Colleagues and management are approachable, They want you to succeed. Amazon is data driven. Everything is measured and monitored, and decisions are made based on facts. Compensation, Travel expense coverage (train, parking (has a cap)), Brand Recognition, Comprehensive benefits package, Extra perks.
Cons
Documentation for a given service may not be well maintained. Most of the tooling is internal, so finding solutions to problems you're facing online may not be possible. You are on-call. If you own a service and a flag is raised signaling a service you own is reaching capacity, or is down, you are expected to mitigate the situation. If you agree to a meet a commitment, and you are falling behind, you are generally expected to get it done.
