RTX System Engineer I interview questions

I submitted a resume and cover letter online to be contacted by e-mail five weeks later requesting a phone interview. The phone interview took place three days later with a Systems Engineer. It was about 25 minutes going over my resume and my experiences and how they connected to the position. It was very easy going and I got a chance to ask questions throughout. The engineer told me he would put me through for the on-site interview. I was contacted a couple days later and the on-site was scheduled for the following week, all expenses paid. I, along with the other interviewees, was given a tour of the facility by recent hires, it lasted long enough to ask plenty of questions and get a sense of the environment. After the tour, we were all given a presentation about the company and then sent off to our respective interviews.There were three panel interviews and a one-on-one with the entire interview process lasting about 2 hours in total. All of the interviewers were engineers and each distinct group gave a general idea of the work they did. The interviews were casual just going over my experiences and how it might fit with the work that group did. There weren't any technical questions. After the interviews were over the interviewees collected together and were notified that we would receive a response by the following week. They made me an offer the next day with a written offer sent the following week.
