I applied online, heard back about a month later. I had a phone interview (with two Northrop people), then an on-site interview a week later. Air travel, rental car, and hotel were all provided by the company. The interview itself was only 30-45 minutes, with a panel of three technical experts. They were very polite, and seemed genuinely interested in my background. They wanted to know what sort of technical expertise I had, but weren't 'quizzing' me or anything like that. We got along well. A few days later, I was informed by phone call that Northrop was interested in me, but due to my foreign ties they would need to delay giving me an offer until I got a security clearance. Perfectly understandable, given what they do. All told, a positive interview experience.

I applied online and was contacted a few weeks later. i had three telephone interviews the; first a general interview with a manager, then a technical interview with an engineer, and finally a conversation with the government customer with whom I'd be working. The in-person interview occurred two weeks later. It consisted of a series of 1-on-1 interviews which took all morning, followed by a lunch with the manager, and another quick interview after lunch. Nothing unexpected, we simply discussed the type of work I would be doing and how it tied into my previous experience. I understood there were other candidates for the job, and i was given a date on which a final decision would be made. Unfortunately, this was the last I ever heard from them, even when i tried to make contact later I didn't receive any response at all.
