The hands on experience, plus doing work I would be doing as a full-time employee at a higher pay scale. The field work requires good teamwork and ability to solve problems on the fly. Office work is important and fulfilling, and requires knowledge learned in school. They are flexible and work with school schedules and understand that school is the priority while interning.
What I wish was different
Nothing. It's a good job.
Don't wait to graduate to look for a job. There are plenty of opportunities that will translate into a full-time job.
