Loved having a collaborative and cross functional environment where I could meet and work with a lot of people in the company. I had hands on experience spearheading initiatives and taking on projects and I loved having the opportunity to have that ownership.
What I wish was different
Being able to meet more interns and to have more intern events
Advice
Put yourself out there, always ask your supervisor for more when you're done with a project (it'll improve your chances of getting a return offer), ask questions all the time, and take advantage of all the resources the company offers you.
