I applied online. The process took 1+ week. I interviewed at Northrop Grumman in Jan 2010
Interview
Starts out with a phone screening interview which was basic questions from an HR person. Then you're invited in for an all day interview with fellow engineers. Compared with other interviews for other companies, this one is relatively easy. Just had to talk about past experiences.
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.
