I applied online. The process took 2 weeks. I interviewed at Northrop Grumman (San Diego, CA) in Oct 2012
Interview
Got an email saying they had my resume in their database and wanted to schedule an interview. I interviewed with two team leads, which consisted completely of behavioral questions and went very well. Got a call back for a second interview with one of those team leads, plus two others, plus the department head. It was mostly a rehash of the first interview with the only technical question being about Unit Testing. The team lead that interviewed me both times said I did great and they would do my review, which was about 3 weeks ago. Haven't heard from them since.
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.
