I contacted adcom as I did not get a response from my interviewer. This is the reply. Also, you can use the contact details to drop a mail if you need to. Hope this helps.
"Congratulations on receiving an interview invite! Please provide your interviewer 2 - 3 days to respond to your message. If they still haven't responded within that time, reach back out to me and we will sort out an alternative method.
Thank you,
Michelle
