I loved getting to meet so many amazing professionals and learn from managers from many different fields.
What I wish was different
I wish I had been able to spend more time with the company to really learn all of the ins and outs of their business (but school started soon)
Advice
I would share advice to go in getting ready to get your hands dirty. They will be very impressed if you get down to work and act as though you are on the same level as the full time professionals, while still being humble and open to learning.
