This was in the Division of Economic and Risk Analysis. The interview was on the phone. The person who interviews you will most likely be your immediate supervisor (hence why that person is calling). Most people in their position have PhD's in Finance. Very few have their PhD in economics and even fewer dont have PhD. The advantage of this is that your interviewer will have published some work. Make sure you go and read their work and find a way to incorporate it into the interview questions. Other than that, the questions were pretty straight forward. They wanted to know what your research interests were, what quantitative experience you had and applied knowledge you have of the field.
