KEA Model Test Qs - S&T Background

Hi guys,

I have recently decided to pursue a role in PE. I am a 1st year associate at a BB (think MS, GS) in a group focused on sales of structured products in EM; not at all similar to M&A or LevFin. I have been approached by several HH because of my experience @BB but, because of my role, I have not developed the "typical banker" skillset, yet. 

KEA sent over an opportunity for a PE role in KKR. First-round is a "model test (2hrs) run by Kea at Kea’s offices involving building an Operating Model, LBO, and answering questions on value creation".

Would you please give me some insight on what I should expect or if you know of a similar model I can use to practice? 

Thanks so much!!
