Something changed recently though because yes there are those MBA types but the engineer in the room used to be not a sales type person. Now (earlier this year, just before IO), even the engineers are becoming more like salespeople in my experience. My guess is there is pressure for everyone to make more money somehow?
this is the end result of all publicly traded companies. eventually you'll hit Sears-level of selling where the CEO just straight up puts departments in conflict with each other until the whole thing just falls apart.
