When a group chose you to lead

Tell me about an occasion when the people in a team or group selected you as their leader.

Explain why they picked you and what you did with it. Briefly give the context, the qualities that led to your selection, and two or three concrete actions you took (setting direction, dividing work, resolving problems), finishing with a measurable result. Interviewers look for leadership grounded in trust and delivery rather than title.
