"It would depend on the disagreement. If the disagreement was with a senior fellow, I would defer to their opinion as they have more experience than I do. However, if I was concerned that they were making the wrong decision regarding patient care or providing subpar patient care, I wouldn't hesitate to discuss it with them respectfully. If necessary, I would go to the chief resident. For more serious issues, such as ignoring patient care responsibilities, I would go directly to the attending physician because these actions, or inactions, would be done under the umbrella of the attending's medical license."

For a colleague disagreement, you should go to your senior on the team. For disagreement with your senior, you should go to the chief fellow. If there is a significant and imminent risk of harm to the patient, you should go to the attending physician. Walk your interviewers through how you would first try to handle the disagreement among yourselves and then take it up the chain of command as necessary.
