I got the invitation last week. Two other friends got the invitations at about the same time also. I don't know any other people applying to that program. I wonder if they would send out rejection emails. But the information I got seems to tell me that they have selected all interviewees, coz I got all my interviews already set up. I'm very nervous about the interviews now.
Try email the HST coordinator. She responses pretty quickly. You know what it means if you don't get a response. :|
