What are some questions to expect for a First Sergeant interview?

SFC Szabo, a discussion about your leadership philosophy is something certain to come up. It will be a "discussion" too, not a simple question about it. Truly, if you understand YOUR personal leadership philosophy and can effectively articulate it, I think you are ready for any leadership question. Even those subsequent questions that present you with a tough leadership challenge as a First Sergeant and you are asked about how you would handle the situation. Not talking about management and leader tasks relating to programs that a 1SG is supposed to be a SME (NCOERs, AR 600-9 etc). Talking about those tougher leadership questions that have less to do with you getting the right answer and more to do with understanding your leadership style. So, your philosophy serves as a foundation for your leadership style and guides your actions and decisions. Your philosophy and style (actions/decisions) should match up -- do you 'walk' the 'talk'.

You can review some others' written leadership philosophies, which you can find posted almost everywhere. Many will sound similar, not because they were simply copied from someone else’s, but more likely because there are common principles that many military leaders strive to embody. Examples are "Lead by Example...", Clear Communication ...", Develop Others ...", "Resilience and Accountability ...", etc. Take note of those common principles and some will likely apply to you. However, do not stop there. I am thinking that it would be a good exercise for you to take a little time to also think about your principles and write some of them down. It's a personal and introspective process about YOUR values and beliefs, and principles that guide your judgment. Knowing these and including them will make your leadership philosophy genuine -- personal. When you know yourself, your values, and the principles that you adhere to that guide your actions, which guided you to this point in your career, you're at the point where you could talk about your personal leadership philosophy for hours and answer any question.

Writing your philosophy is both clarifying and eye-opening. It allows you to articulate clearly to others who you are and how you lead. Best of luck.

If I was sitting there, I would ask:
"Talk me through the EPS process", "Talk me through the Enlisted PME requirements", and "what is the 1SG's role regarding all NCOERs in the company?"

That's because I think every kid in the company should understand the EPS process, understand their current PME requirement and the full path, and every NCO in that company deserves a timely and accurate NCOER.
1SG is a pretty big job, but these three things are the toughest to get done (especially with MDAYs in the Guard), and most important part.

I totally get the jitters before an interview like that. When my buddy was up for a similar role, they drilled into leadership scenarios, especially conflict resolution and morale boosting. It's all about showing you're the kind of leader who not only talks a good game but also steps up when it's crunch time.
