Just reread Ankur Kumar's post, which I basically interpret as invitations will be on a rolling basis upto 11/11. I will start worrying on 11/10

She says:
I know you are all eagerly awaiting news on the next steps in our process. This week, on Thursday, October 27 we will begin to send out invitations to interview. Invitations will continue to go out up until Friday, November 11. During these weeks, you will receive an email that will provide next step information regarding your status with Wharton. If you are invited to interview, you will be given instructions on next steps to set up your interview. If you are not invited to interview, your process with Wharton is closed for this application cycle.
As a reminder, interview invitations are not released in any particular order, as we don’t read your applications in any particular order either. Please don’t stress if you don’t receive your invite until the last day; it indicates nothing about your candidacy.
