JP Morgan CIB Risk First Round Interview

Hey everyone, I completed my Hirvues for JPM a while back, and I heard yesterday that I will have a first round phone interview for the CIB Risk division. I know this is pretty late, but I am from a non target. I was just wondering if any of you have already gone through the process for CIB Risk, and if technicals would be a component for the first round interview. As of right now I have prepared basic things such as behaviorals, current market data, and a stock pitch. Should I brush up on things like WACC, DCF and Comps as well, or would that be a waste of my time. All of the other first rounds I have had have been pretty basic, but I was am just looking for some input. Thanks.
