Unless you specifically want to coach at that school (if you are also a teacher there, for example, or the nearest other school is 20 minutes away), I would say just be completely honest in your answers.
There aren't many coaches out there willing to put in the time. You are best off presenting yourself exactly as you are and being paired with an AD/head coach who you get along with.
I think it would be a mistake for example to enumerate how you plan to help the wrestling kids only there for weight loss before wrestling season just as much as your all state runner, unless you actually intend to do so.
Once you're in, you'll start to feel a sense of responsibility to the kids you coach. If you don't like the AD and other coaches, you'll be in a hard position of wanting to continue helping those specific kids but unhappy with the rest of coaching. A bad head coach or AD can make it miserable for you. A coach and AD who you work well with and have your back let's you focus on doing what you want to do: coaching I whatever your training philosophy happens to be.
At the school I coach at, there hasn't been a coaching job posted in a decade. I was (unknown to me) being felt out for months before being asked if I wanted to come onto the staff. As a result of this philosophy, we all are on the same page and work really well together. We also have very low turnover. I'm the newest coach, entering my fourth season. Every other coach has been there at least 10 years, three of them for almost 30 years.
