Take time to determine whether you have relevant, translatable experience in this regard. If you have, use the STAR method to describe the Situation you encountered in your example, the Task at hand, the Action you took, and the overall result. If you don't have any experience that translates, offer the experience you do have, and detail that you understand that it may not directly translate to the position you are interviewing for. Offer your understanding of how this relates to the position, and eagerly ask clarifying questions as to what is expected.
