The interviewers want to see that you have a keen interest in continually learning your craft. The optometry industry is ever changing! Talk about how you stay up to date on industry trends, new breakthroughs, optometry related concerns, and more.
List a couple of optometry related medical journals that you like to read and discuss how often you dive into related news. Perhaps you subscribe to a particular magazine, blog, or follow certain social media accounts.
It's also a great idea to ask the interviewers about their favorite ways to stay in touch on related current events. Asking this question in return can make for a great dialogue, and you never know what you will learn!
