PJT Secondary Advisory Super Day (Modeling Test)

I've progressed through multiple interviews with various companies, but have landed on PJT being one of the more intriguing options. I have 2 BB internships (only 1 in IB), but really love the concept of working in the secondaries market in a growing group. The super day is this Thursday at the office and requires a 1.5h modeling test. Does anyone have any experience with the typical ask here? I'm assuming I will be provided some type of shell and some list of assumptions, or data with which I can fill out. I just am not sure what to really expect. Any advice/suggestions on how to prepare is greatly appreciated.

Thanks!
