I have been compiliing a list of questions to ask at interviews from previous posts on SDN. Since the search function is down I will post my list here.
You'll notice this is a very long list and many of the questions can be answered on the programs' websites. My plan to make this more manageable is to identify any straightforward questions about the curriculum, patient population, research, etc. that aren't answered on the website and ask the residents/faculty the bulk of these. For interviews with PD's, I'm going to be more selective and choose about 5-7 questions that address more philosophical issues (e.g. what does your program offer that is unique? what aspect of your program are you most proud of? what qualities are most important to you in selecting residents?). My hope is that these open-ended questions will allow me to evaluate how well my goals/priorities fit with the philosophy of the program, and at the same time give a glimpse of the PD's personality and passion for their program. Tried it once and it seemed to work pretty well, so we'll see how it goes from here. Anyway, here's the list:
