Northrop Grumman Systems Engineer III interview questions

I was made aware of a job opportunity through a former member of my research group reaching out to my advisor at school to solicit applications. After a brief phone interview, they brought me on site the following week. That interview was with many people for 20-30 minutes each, 1 HR person, 4-5 engineers, 2 managers (boss and boss's boss). No hard technical questions, but a few from the engineers. Overall people were friendly and helpful. Got an offer the following week.
