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.
