I don't Facebook. I would imagine there are others who quit using it too. It's just a bunch a people fighting over politics. Facebook has become unusable. Hopefully we will have a Discord, Telegram, Slack, or Google meet/chat in place of it for sharing.
I think they said they may have one more date for interviews depending what happens with the second round of acceptances. The interviewees who interviewed pre December still have a chance and so do the post December if were not invited the second round. The second round has until February 22 to make their deposit and background check. Then they will know how.many seats are open for the third round. Following the December invites, there were around 30-35 seats still available. I don't remember how many invites were sent out in December but I think it was around 100. There was around 250 interviews and over 1800 applicants this cycle. I believe their application was open until February 1st, so they are likely still reviewing a few applications.
