Pros
Working on submarines and aircraft carriers is amazing. Coworkers are fun. Lots to learn.
Cons
Benefits get worse every year and more expensive. No raises or tuition assistance until 2017. HR is there to protect the company and not only do they not look out for employees, they will actively ignore management requests for promotions. Interns with one summer worth of experience are offered better salaries (in some cases $8k more) than employees that have the same academic credentials and 3+ years experience. Not sure why it's so hard for the company to figure out why employees are leaving and talent is hard to keep. HR is broken. The famous Apprentice school is worthless if your goal is to be an engineer, none of your experience counts and neither does the time prior to your degree.
