Case Study for VP Interview

Hi all, I’m interviewing for a VP role at a real estate PE firm. I’ve been through seven rounds of interviews (3 MDs and 4 VPs, mostly Zoom) and had a 1-hour in-person interview with one of the MDs. The team and role feel like a good fit.

Now they’ve asked me to sign an NDA and complete a case study. The role focuses on a different product type, but my skills are largely transferable (I’m currently a VP in an investment role at a well-regarded developer, with 6 years of highly relevant experience post-MBA and 4 years pre-MBA.)

Is it standard for PE firms to request case studies at this stage? Is there anything specific I should focus on in my response to best highlight my fit for the role? 
 

Many thanks in advance!!
