RTX RF Engineer interview questions

Flew out to the Missile Systems location in Tucson, AZ with about 160 other potential candidates in a hiring event. They had booths set up interview day to interview all candidates for many different positions of all major types. Well, before that I had a phone interview where the hiring manager himself called me to discuss my projects/ resume. He said it sounded relevant and invited me out to the hiring event. Interview went pretty well, just basically asked me about my resume again ( I spoke to many other candidates and they all said they had the same experience ). They also asked me if I had any experience in RF. I didn't have any experience, but I figured they liked my resume enough to interview me for that position
