Northrop Grumman interview questions

I applied online in January and received an email from an HR recruiter two weeks later. We set up an in-person interview another two weeks later. The interview was a panel of three employees and we went over the position and whether or not I was able and wanted to do it. It lasted about 30 minutes, and I got a call back about a week later. Everyone was very friendly and cordial. Very painless process overall. After I accepted, I underwent a background check and drug (urine) test.
