General Dynamics Electric Boat Engineer II interview questions

I applied online through their career website by submitting my resume. A week later I was contacted by HR to schedule a flight out to interview. This phone call wasn't an interview or a phone screen. Set up travel with their coordinator, but because I was coming from the west coast I needed to stay an extra day to give me time after the interview to get to the airport. This extra day allowed me to get to know the surrounding area including Mystic, which was where the hotel I stayed at was located. They arranged the flight, rental car, and hotel. I submitted receipts for gas, airport parking and the $25 per diem for food that they allot via prepaid envelope to their accounting department. The actual interview: I was given two time choices, 11:30 or 12:30. Dress: Suit and tie. Progression of events were exactly as it was outlined. Check in, submit docs, already had clearance so waited for the rest of the group to get their temp clearance to go on the tour. The tour was ok. The interview was panel behavioral questions. Easy easy easy. Practice STAR but minus the T... Situation, Action, Results. My time was up quickly, when I got back to HR I had my offer waiting for me for the all the departments I was being considered for, it was up to me to choose where I wanted to go.
