I applied in-person. I interviewed at Northrop Grumman (Newport News, VA) in May 2010
Interview
Prompt and professional. Interview was two phases. One with the person I was replacing and the other with the manager. They made me feel relaxed and was very friendly. The HR department was outstanding and provided me all information I needed
I applied online. I interviewed at Northrop Grumman in Apr 2013
Interview
HR contacted me to schedule an interview then had an interview with a manager who was interested in your qualifications. The interview was fairly standard, asking general behavior questions, going down my resume to review my experiences, and if I had any questions for him.
I applied through college or university. The process took 1 day. I interviewed at Northrop Grumman in Sep 2014

Interview was pretty laid back. Mostly just talked about my interests and projects that I had worked on. Got a call the next day saying I had the job. Very quick process.
