Medicine is a continuously changing field where new technology and processes are developed and introduced on a regular basis. Those that remain stagnant in their knowledge fall behind very quickly. For this question, the interviewer is looking for you to have a passion for continuous learning in your field. Talk about any continuing education you have pursued or any journals/publications that you subscribe to and/or read.
"I am a firm believer that being a career long learner is extremely important as a physician. I often participate in workshops that are focused on introducing new treatment plans and/or medications so that I can be familiar with new options for my patients. I also subscribe to medical literature."
"After graduating from a great medical school and having extensive internship training, I knew I would be entering the workforce prepared to begin my career. However, I believe that being willing to learn something new every day is crucial to be an effective health care provider. I participate in health fairs and workshops that are aimed at educating providers on new techniques and treatments and keep current copies of medicine journals to refer to."
