I applied through an employee referral. I interviewed at Northrop Grumman (Chandler, AZ) in Mar 2018
Interview
Very comprehensive. Multiple interviews with various technical and non technical questions. Everything was pretty straightforward and felt more like a normal conversation rather than an interview. 2/3 technical questions were not particularly difficult. The final question was pretty hard though. It did take a few hours to complete.

I applied through a recruiter. I interviewed at Northrop Grumman in Oct 2020

Group interview with multiple candidates where multiple departments were providing background information. There was no official interview questions, but basically just a company sharing their type of work. All electrically focused.
