Collaboration and communication are key. The prototype shop is a high-demand area with a lot of projects going through, so learning to prioritize and time management are some of the most important skills to apply. Communicate back with the engineers and requestors who have brought projects as well, most people are very understanding and flexible about the need to prioritize, and they will work with you to maximize everyone's success.
Chicago is an amazing city, definitely get out and explore the local area.
