Pros
Within the AWS section of Amazon in Dublin, and specifically within the Support area there is a very open nature about the team. You can try, learn or pursue pretty much what you want if it aligns with your long term career goals you discuss with management. Management are engaged often, and in direct areas. You ask what you want from them during regular meetings, rather than the other way around. Amazon always encourages self-driven career growth, so you can work as quick as you like at your own pace. This can be a benefit or not, as it means if you want something you need to do the work yourself for it, and won't be promoted or given anything unless you build it, create it, do it yourself. The position creates a great place to learn though, and you'll quickly find yourself in demand after a short time here
Cons
Part of being able to learn so much so quickly, and do what you want means that you are often left with a feeling of not knowing what to do next. It's difficult to find something to work on next, because of the choices available and this can lead to leaving the team for other areas within AWS.
