Yes. Leadership is about influencing people and driving an outcome, not about having direct reports. Club and sports examples can be excellent because teammates and peers often have no formal obligation to follow you.

Choose a story where you had to create direction, handle disagreement, motivate others or make a difficult decision. Simply being president or captain is not enough by itself.

Explain what you personally did and how other people responded. The interviewer should be able to see the mechanism of your leadership, not just the final result.

Use the title as context, then spend most of the story on actions, tradeoffs and impact. A smaller example with real influence can be stronger than a prestigious title with little substance. For more detail, see the consulting interview guide and the case interview overview.

Leadership without formal authority can honestly be a stronger story than having a fancy title.
