Amazon

Felt like I had a lot of real-world impact. My manager was one of the 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.

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 every day equals a better intern experience equals a better conversion rate).

The team also wasn't the most social one around, but hey, it gave me more time for relaxing on the weekends, I guess.

Find the right balance for your interns. Most of my friends were overworked. A difficult project can be rewarding, but it's got to still be in scope for a college student who is still learning.
