I have been working at General Dynamics Electric Boat full-time (More than 3 years)
Good place to start a career. Overtime pay and flexible hours. Work is usually easy.
The work is not going to be at the cutting edge of engineering. Its fairly basic work. Most of the engineers don't do any actual engineering. Lots of paper pushing.
Advice to Management
As the company grows its competing for talent against the rest of the country, currently talent seems to be discouraged. The reason people stayed in the past was locally EB is the best, but to a non-local the job search is probably across the country not across southern Connecticut.
I applied through college or university. The process took 2+ months. I interviewed at General Dynamics Electric Boat (Groton, CT) in April 2017.
Met recruiters at college career fair. Had an in person interview on campus next day. Was told to apply online. Received a call about 3 weeks later then had over night stay for interview in Groton, CT. Paid for travel and hotel expenses and food up to $25
