I work at a FANG and there was a reshuffling in my team of 30 people as a new manager came in - there were 5 women/25 men. After the reshuffling, the 5 women became the 5 new TLs of the 5 projects our team was subdivided into. And the manager talks all the time about how he wants to empower women. Not sure if that counts. I guess it could have just been coincidence.
