I work at Meta :) The growth I watched in headcount over the last 4 years has been pretty amazing. Before Meta I worked at Reddit. More people were in my bootcamp class at Meta than the entirety of Reddit at the time. And they did bootcamps like that every week for years.

I don’t totally disagree with you. People at Meta work hard and they optimize everything and psc for better or worse definitely encourages performance. But I don’t know where numbers like “overhired by 10-15%” come from. I don’t think things were falling through the cracks and not being optimized before the company doubled in size.
