I applied through a recruiter. I interviewed at US Marine Corps
Interview
The Officer Candidates Office (awkward to say, I know) had one officer and two enlisted marines. There was also an ex-marine who was at the front desk, taking phone calls, sending emails, filling out paperwork, etc. I walked in and said that I wanted information about the officer training program. I immediately got to sit down with one of the enlisted marines (a Gunnery Sergeant), and he asked me general questions about why I was thinking about becoming a Marine Corps Officer. There were no weird interview questions, like what you may get from typical companies.
