I applied online. The process took 1 week. I interviewed at Northrop Grumman in Oct 2012
Interview
I applied online and a recruiter contacted me to setup an interview with manager. Phone interview is more about experience and resume. The site interview was with 3 lead engineers and manager. Questions were the typical for a java software engineer including concepts of polymorphism, abstraction, etc.., databases and they asked me to write a little program.
They contacted me for an in person interview and then asked me leet code style questions. After the interview I heard back from a recruiter who set up another phone call with me
I interviewed at Northrop Grumman (Huntsville Park, AL)
Interview
Technical questions and behavioral questions (STAR formatting) with the normal what draws you to work for us. Microsoft Teams meeting with a panel to review answers. Took roughly 1 hour and it was a very straightforward and easily made process.
Formal, not too stressful. Ensures you understand the basics and thay you know what you're talking about as you may be getting interviewed by somebody that's technical at some point.
