BB PE fund Superday

Hey guys,

I have a superday coming up with a PE fund based out of a BB bank, think like GS PIA, etc..

Anyone have any advice regarding prep for superdays/how they usually go in PE vs. IB and any nuances from being at a bank's PE arm? It'll be in person in NYC so was also wondering if I should just take a sick-day from work as well (not sure how that will fly). 

Only had a paper LBO leading up to this so I assume there will be a case study/modeling test. Was wondering on the more senior level what questions may come up eg. Interesting industries or more behavioral type stuff.

TBH I'd really love to nail this just so I have an "out" as a brain-fried first year at another BB, which I know is not the way to approach PE interviews haha.

Thanks in advance!
