How many PMs does Snap have anyway? Is 20 significant?
As for if PMs are required - most PMs hired are already pretty sorted career wise in my experience (e.g. IIT IIM ISB, ex-Consultant, ex-IB, ex-Engg etc.). If their new roles were āmade upā theyād have switched. Fact remains - PMs enjoy pretty high job fulfilment satisfaction vs other careers.
As for what runs on GV - as you said, most folks here are Engineers. the roles are such that thereās unavoidable friction so most opinions have anti-Product taste. If the democratic opinion on GV was correct a lot more of us would have been fired long time ago.
