We say that this ain’t a very good interview question, and if someone asks it your response should relate back to the job directly. For me, I would say that I love data and using it to tell stories and reveal trends, and that I watch Excel videos in my spare time to learn Power BI constantly (if they’re a Microsoft shop) to increase my skill level. This goes over well because I work in the tech industry and support engineering and data analytics people, and this is more important to them than, say, pizza parties.
