I applied in-person. The process took 1 day. I interviewed at US Marine Corps (Mission Viejo, CA) in Feb 2012
Interview
Walked in and sat down with a Sergeant of the Marine Corps then properly greet one another. Everyone in that place dressed professionally and talked with strength and loyalty towards their job. The area was clean and desks were organized. It made it a comfortable setting and the Sergeant was easy to talk to.
Interview questions [1]
Question 1
What will you do in the future? What are your plans for school/college? Ever thought about serving for your country?
