Northrop Grumman interview questions

I applied for the position at the beginning of March and was contacted about two and a half weeks later by recruiter. The recruiter called and asked a few questions about location preference (they were hiring for OKC and Melbourne), degree completion, start date, security clearance, etc. The same day I received an e-mail to schedule the phone interview which was the following Monday. I completed the phone interview and didn't hear back until two and half weeks later. I was contacted by a different recruiter and had to call their security department to verify my security clearance. About a week and a half went by and I was e-mailed to scheduled a in person interview. The interview was the following Monday. After the interview I got an e-mail asking for permanent address. The offer came about a week later. Long interview and onboarding process even with security clearance from the military.
