This question is a bit similar to "Tell me about yourself." Share a few things that are relevant to the job and give the interviewer insight into your personality. Since you'll be working with people, talking about spending time with friends would be a good thing to share. You can mention hobbies that require attention to detail, like reading and writing. You can talk about sports that require perseverance or goal setting, like distance running. Be yourself! Maybe consider sharing something that makes you unique that will stand out above other candidates.
