Facebook is shooting itself in the foot. There is no point in promoting anyone internally as a manager. It is best if an IC leaves for another FAANG so that you can rehire them as a manager in two years' time. This approach also encourages a heavily bloated hierarchy. If I want to progress, I best promote a cleaning staff member to Director Of Sh*t and have them report to me. In return, they can have several managers reporting to them, who then manage smaller groups of cleaning staff. This approach favours empire builders, who are constantly scheming how to build their empires but are not necessarily adding any value to the company. The staff that are contributing will end up leaving for another FAANG as there are too few opportunities for internal growth.
