Pros: Great work environment. Everyone was very nice and always willing to help me with any questions I had. Also, as an intern, you would think that you would get a bunch of dummy work that no one wanted to do, but that's not what happened at The Trade Desk. All the work I did felt important and was important.

Cons: Not many cons. It's a pretty nice place.
