Pros
Good team. Hard working people who love what they're doing. The operation is really self-contained. You get to see all stages of design and production. Comparing what I did in my internship with what my classmates did at companies like BP, Airbus and Rolls Royce, I was given far more responsibility and benefitted from more contact with senior engineers.
Cons
The work space was small, in a basement at the time. I don't know if things have changed.
