this is the wording I received from the process update email about 2 weeks ago:
'12 November through 20 November 2020: Interview
During this period, select candidates interview with a member of the Stanford MSx Admissions team. Interviews are by invitation only and are required for admission. If you have not received an interview invitation by 20 November 2020, you will not be admitted in this round.'
Seems like the actual interviews will take place therefore between this Thursday and next Friday....I imagine those who are successful in getting an interview will get the interview invite very soon
I think Stanford MSX calls pretty late and close to the actual interviews. That's what I felt from the previous years threads.
