In order for any workforce to be successful, there needs to be unity among the employees. One way to achieve this is through a shared culture. The more an employer knows about you personally, the more they can determine if you will fit in. Additionally, a question like this one is designed to figure out your level of experience for the job. If you sound seasoned and mature, the employer will see you as a good addition. You don't need to be too specific when answering the question, but do share details that would be relevant to the employer. Being friendly, and even a bit humorous is okay.

"Sure. I attended college at Virginia Commonwealth University for all four years. I majored in Photography and Film. Following college, I worked jobs outside of my major for a while. Since I couldn't find a job in photography, I took photos during the weekend for fun. My hobby included taking photos of people in the city, nature, and different things. Eventually, I ran into someone who wanted to hire me, and the rest is history. I have ten years of photography experience outside of college with hundreds of happy and satisfied customers. And, I still have time to take photos for fun, either for family or myself."
