Dropbox

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.

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.

Scale carefully. Dropbox can only continue to succeed if we continue to get good people here.
