The interviewer asks this question to gain insight into your personality and see that you have a healthy work/life balance. Mention several hobbies and why you enjoy them while avoiding interests that could be considered unprofessional. It is best to mention hobbies that showcase your strengths, skills, and passion that can transfer to your job as a dementia care specialist. For example, if one of your hobbies is volunteering at the local food bank, it shows the interviewer that you enjoy helping people and are empathetic and compassionate.
