Don't spend 15 minutes giving a long narrative account of your life (your interviewers will probably stop you/redirect you if you do). Be cognizant of how long you spend answering this question, aiming to share some personal details without going overboard. If the interviewers have follow-up questions, they will ask! It is okay to mention your residency experience but do so within the context of how it's shaped you as a person, not how it drives you professionally.

"I'm originally from Wisconsin where I grew up in a pretty typical household and followed what most would consider a "normal" academic path. I started riding horses when I was 8, which is a passion of mine. I actually thought I might become a rancher at one point before I realized I was more interested in caring for people than pets. One day, I'd love to own my own horse and have a little bit of property too. I'm actually the fifth physician in my family, and I was lucky to have amazing support throughout medical school and residency. My brother and I are very close. In fact, if I match here, he's thinking about moving to the area. As you can imagine, my life for nearly the last decade has been largely focused on medicine, and I'm really proud of my accomplishments."
