The people. The work. How much I learned about my future work-life for my major from 1 year of working in total.
What I wish was different
The location; a bit too far from everything and nothing to do in the town. Very rural location. The organization and documentation processes. The work hours (6am-2:30pm).
Advice
You're probably going to have a lot of questions. Don't be afraid to ask about anything. You're probably going to make a few mistakes. These are fine as long as you own up and do your best to prevent making them again. There will be coworkers that you don't get along with; just make sure to stay professional when the need to interact with these coworkers arises.
