Avoid answering with activities or hobbies that the interviewer might deem inappropriate. If hired, you will be a reflection of the company, and they do not want to hire someone who has hobbies or interests that might be misconstrued as unprofessional. For example, you might like getting together with your friends and going to bars and nightclubs. While there is nothing illegal or inappropriate about that, the interviewer might think that you are a partier who may have trouble showing up to work on Mondays.

"In my free time, I like to work on landscaping my yard, going to the beach with my family, and riding dirtbikes. I recently bought a new house and am redoing the landscaping to make room for a garden for my wife. My son recently took up surfing, so we will go to the beach when the waves are good or ride our dirt bikes on a track I built behind my house. I pretty much spend all my free time doing outdoor activities."
