Northrop Grumman interview questions

Basic interview to start out and then we went into theory. 3 rounds of questions. Then three other interviews at ascending levels. Received an offer but then it was rescinded for whatever reason. Ok..

It was a long process to arrive at a zoom interview. I applied early October. I took a online management ready assessment that took two hours to complete. I was then asked to answer a few questions from the talent acquisition recruiter., and then I wanted for nearly 3 months to get a 30 minute zoom interview which was a very good and practical conversation regarding previous work experience and management style. However I wasn’t selected.
