The interviewer wants to hear an example that demonstrates your leadership skills. Before your interview, think about your previous job experience where you stepped up as a leader to contribute to the overall success of a project. Tie your example to the leadership qualities you'll bring to the role you are interviewing for.

"A few months ago in my current position, my boss had an unexpected emergency that caused her to be out of the office for two weeks. During this time I stepped up and took over responsibilities such as leading the weekly meeting, submitting reports, and making sure employees were on task to meet deadlines. My boss appreciated my effort and was pleased that operations continued to run smoothly."
