Unless you feel inflexible on the matter, don't say that you always play the same distinct role on a team. It's likely that your role changes over time and as you gain authority. You can also probably adapt to a certain extent, depending on what the team needs, so don't paint yourself into a corner with this answer.

"In a new team, I am typically quiet. I listen and observe to understand the team's culture and ethos. I am willing to put in the time to accomplish tasks, but I might not speak up frequently. As I get to know the team and my role better, I tend to share my ideas more freely, though I am careful not to take up too much space. I notice patterns when some people contribute significantly more than others, and I try to encourage balance actively and passively."
