After applying online, I checked periodically on my job page to see if my application status had changed. After 2 months, the status changed from "under consideration by recruiter" to "under consideration by hiring manager", but I never received a phone screen or email. And about a month later, my status changed to "Interview". Several days after seeing the update, I was sent an email by my recruiter with instructions for a phone interview. The hour-long interview was relaxed and not very demanding, but I was asked a bevy of typical interview questions. I recommend others study their answers to those questions, and to make sure they convey to the interviewers why they'd be a good fit with Northrop Grumman. I was given lots of good feedback during the interview because they could tell how prepared I was.
