I applied through college or university. The process took 3 days. I interviewed at Northrop Grumman (Orlando, FL) in Feb 2019
Interview
1 and done. Easy interview. Verbal technical interview explaining what you've worked on and experience in the industry. Behavioral interview covering the basics such as strengths, weaknesses, STAR question structure
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.
