The few things I can think of:
- HR didn't really do a great job bringing interns in, we didn't meet any of them until our second week. It would have been great if we got a list way before hand so we could've gotten housing together. (We ended up making friends anyway)
- Intense security, theres nothing anyone can do about it because of the nature of the work. A lot of people don't like this but I thought it emphasized how important the work we were doing was.
- I should note that experiences are going to vary drastically based on what group/division you're in, not all interns had the same experience I had.
