Meta Product Manager interview questions

The worst experience with Facebook and makes one wonder if this is a leading indicator of decay in the company culture and company overall: -I was told by the recruiter that I passed the interview. -Two weeks later the same recruiter came back and said that they changed their mind. -When I asked for a call to get details, I got an invite with the following subject “FU, 2nd rejection”. -When I inquired about the title, the recruiter said that the title was a mistake... She encouraged me to keep applying to other positions on the call, but never responded when I sent a follow up email. -It has been over a month since my last interview and I still didn’t get a clear response from the recruiting team on where I actually stand with the company! If the company cannot operate a recruiting process and doesn’t treat candidates with the basic respect, one wonders if this is early signals of the scaling issues and it is now being run more as a Borg ship, where you are treated as somebody who has a number rather than a name...I am very disillusioned with the company at this point.
