I interviewed with FB shortly after the Cambridge Analytica stuff came out (but long enough after that it was clear to everyone that FB had screwed up big time).
When it was my turn to ask questions in one particular interview, I gave a standard fallback when I have nothing else: "[despite all the blahblah positives], having worked at other technology companies, what's your least favorite thing about working at FB?"
This guy was a FB vet (maybe 5 or 10 years? Very long in FB time, I think). He gives me this spiel about how hard the teams work to maintain user privacy and how unfairly they're being treated by the public and the media, and how hard it is to work in an environment where everyone treats you so unfairly.
I was floored. Not even a hint of apology, remorse, or "we could have done X better". "Unfair. Fake news. We're doing great things, and no one thanks us enough." And from someone that had probably made a mint having been around at FB near-IPO time. It was my first or second of the day, and while no one else was so blatant, the sentiment persisted throughout the rest of the day.
I bombed the interviews hard, they didn't want me back, but I had basically decided I'd never work there by the time lunch rolled around.
