Just a quick conversation with the recruiter about basic qualifications. The recruiter should have been more specific about the difficulty of the M4 qualifications. I was expecting a follow-on interview with HR but the official offer came a few days after this quick chat with the recruiter.

Easy as long as you have a clearance and passport. They don’t much care for what happens in the interview they just want to make sure you are qualified for the position most people who have a To secret clearance are qualified
