Final Round Interview Tomorrow

I am a non-investment banking candidate for a PE analyst role. I have made it through 3 interview rounds and 1 case study and I am one of four candidates remaining. My final round interview is tomorrow and i've been trying to figure out if there is anything specific I should be looking at that I didnt look at for my earlier rounds. 

The interviews are mostly with the partners of the firm, but also with several mid level folks I didnt interview with yet. 

I feel like my case study will be a big part of the discussion. I've been looking through it to make sure I understand the assumptions I made, I re-read the company profile given to us as a part of the case study. 

My question would be what is generally the final interview round like? I cant imagine it'd be a lot of simple technical questions. I would hope after 4 rounds, they'd have confidence in my knowledge ability. I figured it'd be a lot of fit/behavioral questions, discussions about my case study, and maybe some deeper technical questions
