But in the case of SnapChat and Uber (and many other tech companies), the founders were literally (and archetypically) both Frat Bros and Tech Bros, who set the tone and culture for the entire company, and rampantly hired other Frat Bros from their own Frats, at all levels of incompetency.
Incompetent nepotistic job placement is basically what frats are all about. (Once you get past all that other stuff that Andrew Moisey documented.)
