CDB (just changed the department name from MCDB to CDB) department already started sending the interview if you checked it on results section. They are still reviewing.
UCLA Access will review your application until April (which means all the applicants are in "hold/ waitlisted" status) unless you got a rejection letter from UCLA.
I do not think Northwestern DGP already sent all the interview invites. Northwestern DGP has several interview weekends from late January to early March. I think they just finished the first wave of interview offers and they might send more later.
Good luck!
Yes, Northwestern DGP sent out the interview invitation on Jan. 3. There are multiple interview sessions.
Northwestern DGP program recommends for those applicants who received an interview invitation on Jan 3 to visit school on the first interview session so that they might send out more invitation letters after that.
Wisconsin-Madison Genetics program sent the one wave of invitation by Dec. 18 (letter), Dec. 19 (e-mail). They might consider sending invitation for those applicants who decide not to go to interview after first interview session (1/23 - 1/25). If you look at the result section, one person got an invitation letter after first interview session.
