Not sure if you are talking about MSPP application process and interviews: Here's what their webpage says about admissions. There are several processes in play including Advanced Standing, Early Consideration and General Considerations. General Considerations are still in review for everyone. I hope this is helpful.
below info copied directly from the MSPP website:
for Early Consideration: Friday & Saturday, January 27-28, 2012.
for General Consideration: Friday & Saturday, March 2-3, 2012 and Friday & Saturday, March 9-10, 2012.
Advanced Standing interviews will be scheduled on different dates by appointment.
Interview invitations for Early Consideration are released in late December and for General Consideration in mid February. Interview confirmation is required by the date specified on your invitation.
