Northrop Grumman interview questions

Asked by a friend to submit a resume because they were not satisfied with their applicants. After submitting I was scheduled for a phone interview with two of my co-workers to be. Neither was management level, although that seemed to be an outlier. Softball questions, asked about knowledge of Excel, what can I apply from my major, etc.

Interview was at a hiring fair for the project. Spoke directly with the project manager. The hiring process through hr consists of a detailed background check for the last 10 years and a drug screening.
