Northrop Grumman interview questions

I was contacted by a recruiter after submitting my application, my interview was held virtually. My interviewer was not able to make it in time so a senior engineer who was also on the call conducted the process instead. He asked in depth questions about my resume and what I learned from each experience. He was very interested in what organizations I am involved in on campus. He was interested in learning my career passions and wanted to know where I wanted to be placed.
