I applied through a recruiter. The process took 1 day. I interviewed at General Dynamics Electric Boat (Hartford, CT) in Oct 2015
Interview
Straight forward interview. Toured the shipyard then took a bus to the main building. The interview was conducted by a senior engineer where he went over his job description and went over my resume. No technical questions. Just know what is on your resume and you will be fine. In total I had 2 interviews in the day.
