Northrop Grumman Manufacturing Engineer I interview questions

The hiring manager and a would-be team mate told me a bit about themselves, asked a few basic questions, and said I would hear back in a week. After 3 weeks, I sent an email to the recruiter asking if they had gone with another candidate. A week later, I got an automated rejection email. After this email went out, the recruiter called me to tell me it was a system error and they wanted to move forward. Fortunately I had finished interviewing somewhere else in those 4-5 weeks and was very not interested.
