Insight and help for final round PE interview

Hi everyone, I’m starting my Master’s in Finance in Europe in two weeks and have an amazing opportunity to join the Principal Investments team at a Life Sciences-focused PE firm—if I can ace the final round case presentation. I’ve been interviewing for various finance-related roles, but without a strong network in finance and having completed a less quantitative undergrad degree (though I did attend a target B-school), I struggled to secure a position earlier. I really don’t want to miss out on this chance to join a prestigious PE firm just because I don’t perform well in the case. I’ve been studying the technicals intensely, but I’m still nervous since this will be my first PE case. Landing this would also bring me one step closer to break into IB. I’m reaching out to see if anyone has insights or tips for nailing the technical round of PE recruiting. And if anyone with PE experience would be available to have a 15 min call on August 19th just to guide me if I am going in the right direction with the case please lmk. Thanks in advance!
