I applied in-person. The process took 1 day. I interviewed at US Marine Corps
Interview
No real interview process. Be a great Marine. Show your motivation and initiative. Show case your leadership abilities. Be great at PFT. It pays to network and be liked by your seniors.
There are Marines I served my whole five years with. I made it to Sergeant, and became an Infantry Squad Leader. They made it to Lance Corporal, and never placed in leadership position. Why? They failed the interview process...
Interview questions [1]
Question 1
They don't ask you questions. You are judged by your leadership abilities.
I applied in-person. I interviewed at US Marine Corps (Camp Pendleton, CA) in Nov 2018
Interview
There is none. You just need to simply push yourself until you get to the end. The interview is your time in service. Your ability the pick up and keep rank.
