I called yesterday, and they said that we should hear back within the next week as they have officially decided on the entire 10/6 interview group. I believe they decided on the first two groups (red, blue) already, so people should have received a notification this entire past week (rejections: sent via e-mail on Monday, acceptances noted on portal/mail, alternate waitlist <- not too sure how they notify). They most likely are sending out decisions for the latter two groups (green (?), yellow) next week.
I was in the blue group and have heard nothing. So hopefully they just didn't finish the blue group.
