RTX interview questions

Shortly after I applied through the employee referral process I was contacted by a recruiter. I was interviewed for a position that I did not initially apply for so the phone call was basically to gauge my interest in the position, this call lasted roughly 15 minutes and I was offered a chance to come onsite for a hiring event and interview. I flew to the campus and was taken out to dinner the first night by the Engineering HR group. This gave all the candidates to ask questions about the company. The next day I was put through 3 different sets of interviews. The interviews were made up of 3-4 different people with varying backgrounds. The next day I received an offer for the position that I interviewed for.
