Northrop Grumman Test Engineer I interview questions

I met a recruiter during a career fair and he was very nice and we talked about their team and what work they do. After that we had a 30 min interview right on the spot mostly talking about my previous experience and the projects on my resume. After that, he said he'll be in touch. A week later I was invited to an on site interview which lasted around 1.5 hours. There were 5 people interviewing and there were a lot of behavioural question and specifically asing about projects that i had done relating to the job.

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.
