BAE Systems USA Engineer/Technologist interview questions

Sent in an application and two weeks later got an interview request. Three person interview focused on analytical skills and past related .experiences. About four days later I got called and notified that I would be receiving a job offer.

Was contacted by HR requesting an interview approximately a week after applying. I met with 3 subsystem managers in one of their offices. They were all very nice and joked around a lot. They asked about my experience and education and mostly spoke about working at their company. I tripped up on answering questions.
