Finance Interview Skills Assessment?

I am interviewing for a Head of Finance/CFO role at a small series-A funded D2C company. The current CEO has a Kellogg MBA and has managed the finances so far but is adding this position to really take it over. The first interview went well and was more introductory, and they indicated the 2nd round would be more focused on behavioral questions as well as a skills assessment. I sent a follow-up thanking them for the first interview and requesting some more details about the skills assessment. However, I wanted to check in with you all and see if you had any thoughts on what I should expect. If it turns out to be discussing conceptual/theoretical questions related to finance or business strategy, I feel confident enough to navigate that well. However, I do also want to be prepared for a small case study or modeling request. Hopefully they give me a clearer picture of what to expect, but in the meantime I wanted to get your take if you have experience interviewing for VP-level finance positions at a non-blue chip and any places I could get some cases or scenarios to practice modeling to brush up on building those models quickly so I can be efficient in the interview. 

Thanks!
