How to answer question on application to become juvenile correctional officer?

One of the question's asks to describe a time I had to de-escalate a confrontation with a juvenile and to explain what actions I took and the outcome. It's been several years since I've been in the criminal justice field and I'm hoping to get back into it. I have a couple examples to use here, but they occurred awhile back so I don't remember many details. Other than describing the situation - does anyone know what they might specifically be looking for in this answer? Thanks!
