Northrop Grumman interview questions

Went through a recruiter who contacted me within 4 days of my applying. Then after a week the face to face interview was scheduled with a NG manager. One hour long face to face interview was scheduled in Woodlawn, MD. It is my understanding that THAT was the only step to an offer.

Met different employees at various on-campus events. They were all engaging and helpful in helping me determine what area and positions I would be a good match for. After a career fair, got a call for an interview. Ended up interviewing with someone I had met previously at on-campus events. The time set aside for the interview was ~45 minutes and the atmosphere was friendly. The interviewer asked one or two technical questions and a few behavioral questions (describe a time you had a disagreement among your team and how it turned out, etc.). I definitely over-thought the technical question, but otherwise it seemed to go fine. At they end the interviewer informed me that there would be another round of interviews for chosen candidates. I did not hear back from them after the interview. Followed up ~1 month later and still did not hear back from them.
