Preamble
A couple of very wise mathematicians once told me that the list of possible interview questions, while large, is finite-dimensional. As long as the questions that you have prepared for “span” the space of all interview questions, if they ask you a question from outside of your list, then you should be able to repurpose/combine answers to a few other questions to answer it. The purpose of this webpage is to provide a long list of questions for mathematicians to practice from. People in other disciplines may find some of them useful as well. Different questions may be more suitable for different levels of interview (e.g. PhD, postdoc, faculty, etc).
