I applied through college or university. The process took 2 days. I interviewed at Lockheed Martin
Interview
Lockheed comes to campus and gives an info session. At the info session you network with the recruiters and turn in your resume. They'll call you for an on campus interview. If you pass the on campus interview they'll call you in for an on site interview if not they won't bother notifying you.
Interview questions [1]
Question 1
Most questions depend on your resume. They mostly ask you questions about your experience and how those experiences would help in a systems engineering role.
