I applied through university. The process took 3 weeks. I interviewed at Northrop Grumman in Oct 2018
Interview
Went through a interview at a conference, then had in person interview that was mostly behavioral with easy casual technical questions. It was a good experience and the interviewer really seemed like he was interested in helping all candidates succeed.
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.
