Great opportunity to learn about how engineering jobs actually work in the field. Great team environment and I am still learning tons from it.
What I wish was different
Wish I could have had more directed training. What I've had is a bit sporadic, but this is because our design team was small.
Advice
Be deliberate with every measure you take as an engineer/drafter because you need to be able to justify all design choices to clients/co-workers. Practice that as an intern.
