Pros

Cons
Undefined road map Too many management and reporting structure changes. Both of the above have lead to lot of chaos in the recent times and has resulted in lot of people from the tech vertical leaving the company. This also leads to uncertainty in terms of career growth as there are a lot of hand-offs between managers. A few people were let go and I feel the management did not come out clean with any reason for those. This created a lot of commotion and uncertainty. And even now it doesn't look they are doing anything to quell the chaos. The amazon leadership principles are used only for interviews. Performance reviews are largely the whims of your manager. So if you are in good books you are safe. Otherwise what you did closest to review would be used for your performance evaluation. There are some good managers who try to be objective so if you are lucky, you'll get them as your manager.
