Consider using the STAR method when answering such questions. Address each answer by first offering the SITUATION involved with your example. Then move into the TASK this situation required. Then share the ACTION you took and the RESULT of your actions. This will add structure to your answers.

"I was working with someone who was leading a team project. I had prior experience with this project and offered advice about how to approach the work. They resisted my help at first, saying they needed to do it their way. I respected their boundaries but observed from a moderate distance. This person asked each member of their team to volunteer for duties, and some of them were interested in their roles, hoping to learn some new skills from the experience. However, this was missed in their communication, and there was little mentoring being done. Soon their project started falling behind. That's when I volunteered my help again, and they grudgingly accepted. I suggested restructuring the teams according to talent and prior experience for the sake of meeting deadlines. I suggested instructing in detail not only what each team member had to accomplish and by when, but why each task was important and how each piece fit into the big picture of the project. Soon, some members were ahead of schedule and could be reassigned to help others. They met their deadline. I then sat down with that friend over coffee and shared my insights. Since then, they have credited me for some of their skills, which they continue to build upon today."
