Pros
This was a great first internship experience. My office put me to work on a construction project, and I was able to get my hands dirty in the field. I got certified in multiple concrete tests which looks great on your resume. After about two weeks, I felt like I was a regular employee. Everybody I worked with was extremely friendly and eager to help if I had questions. The job is a very structured 8-5 (the hours can be flexible) and the only time I ever worked more than the standard 40 hour work week was if I asked to. I never had to take my work home with me. TL;DR: Great first internship. The responsibilities given are not too difficult, and the job is very structured.
Cons
This is a state agency, so of course the pay isn't great. Other offices in my district under-utilized their interns; it is really hit or miss. But, you get out of it what you put in.
