Math Interviews

<p>I'm applying for Math PhD Programs, and I have a question for those who have interviewed with prospective departments esp. potential advisors.</p>

<p>What type of questions potential advisors ask, and what type of questions should I ask them, just to keep the party going? What are some examples of questions that I can ask that won't require me to actually "know" their articles inside and out? Any advice is appreciated.</p>
