Choose a meaningful experience that highlights something you learned that might be relevant to your fellowship training. If you discussed a patient case in your personal statement, you can expand on that story during your interview.

"I once cared for a young woman with infertility issues. Despite her struggles, she was exceedingly pleasant at every appointment. I chose to talk about this patient because she was very undereducated about her health when I first encountered her and I learned a lot about how to effectively deliver patient education over the course of her visits."
