This is a nice question to allow interviewees to describe their likes and hobbies for the interviewer to decide if you will fit the culture of the company. Mentioning upskilling to a company who put emphasis on training and development or stating your fondness for team sport to a highly motivated sales team can be the icing on the cake but to understand what answer to give you must listen to the interviewer's description of the company and try and relate your interests to the role advertised.
