I applied through college or university. I interviewed at US Army
Interview
Interview was easy and quick. Phone call from a hiring manager, and then in-house interview with the same hiring manager. She then introduced me to the entire department and walked me around the floor. She also asked me which office I'd like, that she can go ahead and prep it for my onboarding.
The longest part was waiting for clearance and actual offer. Took about 4 months.
