The online assessment was Java and Python but the time limit was short. Overall it took a couple of hours. Helpful to brush up on syntax before starting. I found the java sections harder than the python sections. Kinda an average technical assessment but the employers do not respond quickly after its completion you just get an automatic mark.
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.
