I loved having the freedom to decide what projects I wanted to do, and the ability to take them in whichever direction I chose. I also liked being able to work in a team environment, and collaborate with others.
What I wish was different
I wish the project descriptions and time lengths had been more clear, so that my fellow interns and I had the ability to organize our time better and allocate our resources more.
Take advantage of those around you! If there is a project or task you're interested in, talk to your coworkers about making that possible.
