Typical Composition of Groups

Hey WSO,

I'm an AN1 in an investing role and I'm starting to wonder if the composition of my group (# of people at each level) is unusual. Could you provide color on what the typical breakdown looks for different roles / group types. Basically do what % of IB groups are MD, ED, VP, AS, and AN? I feel like mine is unusual but curious what banking groups and PE firms look like generally
