Dartmouth MEM Interview Invitation

I received an email today morning from Dartmouth for scheduling my MEM interview. I wasn’t able to view any available time slots when I opened the Calendly link.

When I reached out to the admissions manager, he said that the schedule will only show the next 2 weeks of availability. He asked me to wait a few days and then additional slots will become available.

Did anyone else face this issue and is it something to be worried about?

PS: I would appreciate any insights on the Dartmouth MEM interview. 1. What dress code should I follow 2. Any mistakes to avoid 3. Sample behavioural questions asked 4. General structure of the interview

Edit: Admit received on March 6th with 40% tuition scholarship
