Based on your background, they will either ask questions from Statistics (in particular, Bayesian Statistics) or questions pertaining to programming. The former will usually include full-fledged numericals, for example, you may be asked to find the probability of false positives in a new clinical trial given some data using Bayes' Theorem. You may also be asked basic definitions such as "Intuitively describe what the "likelihood" of an event is and how it differs from simple probability." Both my interviewers were kind and guided me when I got stuck. They do not need you to know the answers in advance, just be able to reason and discuss well and also be able to use a wide variety of tools to tackle a problem.
