I loved the atmosphere, the people I worked with, and how much I learned while working there.
What I wish was different
I loved it all except for getting there at 6 am, but I guess it comes with the job.
Advice
I think it is really important to remember the people you know who weren't intended as a "network". People know people who can become a part of your network. Jump in with both feet and give your all and you will get a better experience in whatever you do.
