Internship is centered around a 3-month-long project with a mentor and a manager to help you. You have a chance to make significant contributions to your team's codebase and even push your code to production. Knowledgeable and friendly coworkers.

Internship is centered around a 3-month long project; if the project is badly designed, you may have a terrible experience (as did I).

Many datasets and tools to familiarize yourself with, some of which are poorly documented. So if your mentor and manager are busy or can't help you, you'll be on your own.

I didn't get to choose what team to work for and what project to tackle; I didn't even get to state my preferences.

It would be massively helpful if we were given the chance to at least state our preferences before going into the internship. I was assigned a project that I was terribly unsuited for, and I had a quite frankly miserable experience.

Most interns had a good time, though, so please don't let my review discourage you from applying to Amazon. I'm just warning you to brace yourself if you are given a poorly designed project.
