This question is for you to ask the interviewer. This will give you an idea as to whether the program is too abusive to learn anything. Being on call every other night for hospital that has 30 deliveries a month and only 50-100 beds is not problematic; but if you're going to be up all night every other night, that's a problem. A good rule of thumb is delivery about 20-30 babies a month but split over several on-call days. You'll want to know if you have the day off after an on-call night"”this isn't necessary if you're not up all night, but if you are"are you expected to put in a full day following? Don't get into these particular questions"”the interviewer will think you're pompous"”just ask what is the typical call schedule like. You'll definitely get the info you seek between the lines.
