Pros: One of the best ways of learning new skills is by working with people who are smarter than you. This is one of the best things at Dropbox: everyone is such a strong contributor that you will always have more to learn. People at Dropbox are as friendly as they are skilled. If you're having problems, help is just a desk or two away; people enjoy when you ask insightful questions, which goes a long way toward setting your mind at ease. Also, the Tuck Shop is unrivaled, which is saying a lot since we're talking about San Francisco here.

Cons: Impostor syndrome was a huge problem for me during my internship. Since everyone is so skilled, I often felt like the worst contributor on my team. If you have an ego, Dropbox will kill it with a vengeance. But you'll come out stronger for it. That isn't to say you have to suffer. The people here are friendly and understanding. Most of them feel the same way and can help you. But it's there, and learning how to deal with it is tough.

Pros: Everyone knows this, but the people at Dropbox are incredibly smart and incredibly friendly.

Cons: I worked on a project that I didn't love, so if you intern here, make sure to be extremely explicit on the preferences form.

Pros: Dropbox has worked hard to keep everything, particularly their intern program, transparent. Interns receive bi-weekly written feedback from their mentors, and return offer expectations are very clearly communicated at the beginning of the summer. While this felt nerve-wracking and stressful at first, I think it helped me grow quite a bit. Full-time employees also have a regular system for peer and manager reviews.

Cons: There are those who keep normal schedules, but I get the feeling that a large portion of the workforce stays late and eats most of their meals at the office. This promotes a nice sense of community, but it takes effort to remind yourself that it is OK to leave work at 6. I also wouldn't suggest Dropbox for people who like to work insularly, don't like the idea of getting lots of feedback, or don't take negative feedback constructively. This is a place where people want to grow and improve through feedback and collaboration.
