RTX interview questions

Got an email from a recruiter at the company after having submitted an application several weeks prior. I was asked to provide a few examples of my work from previous internships and/or school projects that might be relevant to the position. I basically put together a portfolio and sent that over. I got a call about 3 weeks later from a different recruiter. We set up an interview for the following week where I met with 3 managers. The interviews were very relaxed and conversational. They had looked over the work experiences and asked me basically to describe those experiences in more detail, with maybe a few questions thrown in. Everyone was very friendly and helpful. I was told I should hear back in about 3 weeks, and ended up getting an offer after about 4 weeks.
