Start by identifying your career goals and think backwards. You can even start with thinking about how the idea of working in a vet's office came to be. Think back to when you were a child and wanted to hug every furry friend that came within a mile radius of you. You started to notice the differences between different breeds and how some didn't just look different, but they acted differently as well. Did you check out books at the library to learn more about them? Maybe you spent a lot of time with the family dog and taught it how to do tricks. These are some simple examples of the little things you were exposed to growing up can factor into our decisions as we get older. If this is a career change for you, what made you decide to make the shift? Here's an example of how you can respond:
"I always loved learning about animals as a child. I studied books about dog training and worked with my dog since he was a pup. When I learned about this profession, I was excited because it's a way to incorporate my passion into a career. While I understand that there's a lot of dirty work involved, I'm excited to further my education through this experience."
