"I understand this system is in place to prevent poor performance and patient care provided by residents and fellows due to exhaustion. There were times during my Internal Medicine Residency training when I knew the line was toed pretty closely, and by the end of the 6th day in a row working 12 hours shifts, I was exhausted. But, I know that the next three years in training as a Critical Care fellowship training will entail 12-hour shifts on consecutive days, and I'm once again ready for this challenge in progress towards my future practice."

A lot of people are opinionated about this topic, and this could include one or more of your interviewers. For this reason, focus on the pros and cons and don't take a strong stance on this topic. State that you know the rules, why they are in place, and the impact they can have on every Critical Care fellow in training at their program.
