Applied online, heard back with a screening "interview" over the phone.
Got pushed on to a Skype interview with the managers. Quick and easy process, focused mostly on why Northrop is a great place to work.
1 hour video interview + 1 on-site interview. Video interview comprised of both behavioral and technical questions. Majority of the questions were to figure out how you think and solve problem as an engineer and often require STAR format when answer.
