PE Recruiting Preparation Approach

Hey! I'm curious to hear how everyone here who successfully recruited for PE from IB prepared for recruiting, especially considering how accelerated the process is.

Im an incoming analyst at a BB but not sure where to even start with preparing for PE interviews. There is an abundance of resources such as M&I and BIWS for IB recruiting but can't find as many for PE specifically. Would love to hear what resources everyone mainly utilised and what your routine/timeline was for preparing? Did you network too?

Thanks in advance!
