The employees were very nice and helpful. They explained their job and how they did it in a way that was understandable and not overwhelming.
What I wish was different
There was not a whole lot to do, a lot of it was just sitting around waiting for a project to come or work-space to become available.
If you want a more fast-paced internship where you actually have a lot to do, try the main office. The branch office (at least the one I was at) was definitely more laid back and had less things to do/space to do them in.
