It was a really great experience to learn about a field I had not know much about, and to gain great technical skills with ArcGIS.
What I wish was different
I wish I would have spent more time building connections with my co-workers instead of focusing so much on just working.
Advice
The full time employees at your internships are very eager to help you learn, grow and achieve. Don't be afraid to ask them for advice and build connections with them.
