Northrop Grumman Structural Engineer interview questions

Three interviews First was a 30 minute phone screening Second was a one-on-one technical interview Third was a five-on-one technical interview The interviews increased in difficulty as they progressed and all were phone interviews

Applied on Linkedin, the next day got an invitation for a Meet&Greet phone call with the recruiter. Recruiter asked some basic questions to see if I would even be allowed to go through the hiring process (citizenship status, etc.), then said the hiring manager is interested in my resume and wants to set up a video interview. A few days later, went in-depth on everything on my resume with the hiring manager, then was asked a few STAR questions. Phone call with HR manager about a week later, then an offer about a week after that. Whole process took about 4 weeks.
