Types of pods (quant/fundemental + strategy) @ Citadel, Millennium, P72, etc..

Hi folks,

Wondering if anyone has a rough idea of the split between the types of pods at the big pod shops. Haven't found any previous posts on this (?). From what I have understood the PMs are free to choose their strategy, as long as they operate within the risk limits.

So does anyone have an idea what the split is between:

1) Fundemental vs. quant (and I guess "quantamental" somewhere in between)

2) Strategy choice: L/S equities, rates, credit, commodities, macro, vol, ++ any I left out 

Feel like I mainly hear about super detailed bottoms-up quarterly modelling for earnings beat/ miss, so very curious about this -- any rough estimates/ color is appreciated.
