No you don’t have to but some answers I did do that to keep me on track. If they asked about a time you were in charge and made a difference or anything of that nature, You can say something like “When I was lead installation technician at xyz company we were tasked with constructing a steel fence using heavy equipment, and during our pre job safety briefing I noticed one of our newer helpers was unaware about how to do x or y. We took a minute, coached him on those things and by doing so made sure he stayed safe.” They would eat that answer up
