Northrop Grumman interview questions

I applied online for 5-6 positions and I got emailed by recruiters 4 weeks later for two different positions. I got an interview two weeks later over the phone (although it seemed that the interviewers were using Microsoft Teams, they just didn't have their webcam on). I got an offer at the beginning of the week! I also got an interview for a similar position with a different manager the next week, but that interview was different since it was over Zoom and webcams were on.
