Duff & Phelps Transfer Pricing Interview

Hi all,

This is my first post here so let me know if I should post somewhere else regarding this topic. I have a final round interview for Duff & Phelps (Midwest) Transfer Pricing final round interview. Since D&P is known more for their valuation practice, I have seen many interview reviews online say there are technical questions and a case study in the final round. However, I don't believe that Transfer Pricing is as competitive of a practice, should I still expect to see technical questions and/or case study in the final round? I am asking because there are very few reviews of the interview process for Transfer Pricing. If so, what resources should I go to study for a potential case for this service line? I answered a mix of simple technical and behavioral questions in the online recorded interview before this round.
