MTS too. And yes I had my interview mid February. Based on the timelines of the previous years, by mid March, they usually mean 10th - 15th. That’s what led me to think the last interviews might have been done this week.
Unfortunately, but realistically, I think HDS interview window is now over. Decisions will be available anytime between this Tuesday and Friday. Which program did you apply? Also did HDS mention that they have received a large amount of applications this year in any admission events?
My interview was highly structured. I don’t think they asked me anything that is too tricky but given it only 15 mins (that includes the time given to the interviewees to ask questions from the interviewer), I believe direct, short answers would be the way to go. Always remember that they have already read and reviewed your application materials, so l they already know who you are. Knowing that makes your interview an enjoyable experience.
