Applied online and was contacted by HR with a few business days to set up a 30 min interview with the hiring manager. Interview took over an hour and consisted of discussing the role and business and then behavioral and technical questions. Offer received within a few days after.

I applied online before a college career fair GPA was good (over 3.0) and I had one prior internship in the same state as this position Didn't make it past the first interview Since Lockheed Martin has multiple lines of business, knowing exactly what you're getting into will take you far
