Moving from McKinsey/Bain analyst to PE associate

If anyone has made this transition could they maybe share some insight into what the process was like relative to the standard IB -> PE recruiting path? Specifically, do most people recruit first or second year, would a banking internship right before you start significantly help your odds or potentially make you look like too much of a robot/tryhard, what tended to differentiate the BAs/ACs who were successful, etc. Any relevant insight would be much appreciated since there isn't much about this specific transition on any of these boards.
