Was a great to get startup experience under my belt. Got to do a lot of hands-on experimentation and development.
What I wish was different
Company was a little small--- there were only 6 people in the office most days, and it would have been nice to have a group of interns rather than just myself and one other intern.
Advice
Don't get discouraged just because you start slow or in a role that you don't enjoy-- you have to start somewhere and you can only go up from there.
