GS Equity Strats Onsite Question Types?

Does anyone know what types of questions are asked for the onsite interview of Desk Strats (PhD-background) at Goldman Sachs Equity? I understand there will be encounter math/algorithm/probability questions, but I am not sure if the following types of questions are common: - object-oriented design (OOD) - data-structure design, - design data models given a dataset in a real-world context - system architecture design.

I saw these types of questions are common for software engineer roles, and therefore I wonder if they are expected for strats roles. The strats position I am interviewing with involves heavy programming and tool development on GS's platform. Its main difference from pure SDE is that it involves some math and data modeling.

Any ideas or advice would be much appreciated. Thanks!
