Hi there,

My honest advise is to view it no different than the others. 

No need to hype yourself up. So many people each round as another “level” as if it were a video game. It's not! Each round is just as important as the first, and they are all the “same” in the sense that we really just don't know exactly what will happen.

Stay flexible/adoptable. Go in knowing your fit/behavioral, casing, and market sizing. That's “it” :)

Hello,

I agree with Ian that a case interview with a partner is no different from a case interview with someone more junior - the format and expectations are exactly the same. So I would advise you to continue preparing as you would for your earlier case interview rounds. Make sure to incorporate any feedback you have received from Advancy during the interview process so far.
