Pros
Felt like I had a lot of real-world impact. My manager was one of few that knew how to treat interns as intelligent people, and gave me quite a bit of flexibility for my project. I'd recommend it in order to grow a career in the future, as I learned a lot.
Kontras
Some perks would have been nice. Most tech companies offer this, and Amazon tries to drill into your head that frugality is key. While the compensation was nice and I'm not one to demand all of the silly things Google offers, if there was a daily lunch served, this would have made a big difference in my experience as an intern (not having to stress about cooking food everyday = better intern experience = better conversion rate). Team also wasn't the most social one around, but hey it gave me more time for relaxing on the weekends I guess.
