Talk about a time you felt you made a true difference in a patients care or their overall day.

"I was able to stop a patient from shopping around for narcotics. By bringing the situation to light, I was able to help the patient realize that they were in a bad situation and needed to seek rehabilitation. They stopped by the pharmacy two months later to thank me personally."

Getting a simple 'thank you' from a patient could be all you need to know that you are making a difference in your patient's life. Tell the interviewer about positive feedback you've received when you made the right call. Share a story about a time you worked directly with medical staff and monitored the patient's progress based on a change that you made in their medication.
