Thanks for the linkUtilize SDN's interview feedback page for each school you will be interviewing at. A lot of my interview questions came straight from the feedback other students had written about. It also tells you what to expect for your entire interview day, how many interviewers you have, the format, etc. I wrote a list of the most common questions and then came up with natural responses (not memorized). It really helped.
For example, this is Harvard's. Scroll to "questions" and expand each sub-category.
