Such a fun job! Very hands-on (don't be afraid to do grunt work) and very educational. Every night, a different department came to talk to us about their job, ranging from site-ops to marketing to vip. Helped with a little bit of everything.
What I wish was different
There was a lot of downtime, but it was okay because all the interns would hang out together :)
Advice
It is what you make it...talk to everyone about what they are doing. They will gladly explain their job to you!
