This question is basically pitched at you to find out whether your recent employers gave you more responsibilities than a clerk would normally have. The interviewer may want to discern whether you have personal management skills or leadership abilities that would make you the perfect candidate to be promoted down the road.

Answering this question in the affirmative can make or break your application.

Therefore, highlight some of the major projects/responsibilities that where given to you. If you did not have any, but are interested in such responsibilities, mention this idea. If you had responsibilities in a volunteer position, elaborate on that.
