I applied in-person. I interviewed at US Marine Corps in May 2016
Interview
Interview process was straight forward. You apply, you take the ASVAB, and then either get ready to head into training in the next few weeks (if lucky) or wait in the Poolee program for months.
I applied through a recruiter. The process took 8 months. I interviewed at US Marine Corps (San Antonio, TX)
Interview
Motivating, inspiring, persuasive. The recruiter presents several questions about your drive and things that you may want to experience through life, many of which are very common to the normal person. The recruiter encourages you and inspires you to be better than you've ever imagined yourself and encourages you that you will have a difficult time in boot camp, but it will all pay off in the end when you've earned the time of US Marine.
