It doesn't necessarily mean that you won't get an invite. You know, it takes quite some time for them to make calls to hundreds of applicants right? Good luck!
I just got a call at 4pm PST from UCSF Tetrad inviting me for an interview today. Be sure to pick up any call with a number that is withheld. Even if the staff leaves a message, she will just tell you to call back (it happened to me) so be ware.
Yea... I hear you. For me, it actually took me a little bit more than a week (a business week) for all the things to be updated. And yea, they never answered my email and never answered my call. I was super paranoid and used the application status checking system every day....well...at least everything is set now...
