Well, although what you say may be true (that no one on SDN got invited to the interview if GEMS started calling last Friday). There is also a possibility that we are the 24 lucky ones who will be invited to the GEMS interview and than eventually becomes admitted to the program.
Let us all be optimistic and be patient as well. GEMS Program's admission committee have been reviewing applications for many years and they are obviously experts at knowing who is best fitting for the program. Just sit back, trust your application and trust that the GEMS Program's admission committee will do what they do best.
Be optimistic because we can all speculate about what might be happening right now, but truthfully, no one does unless you are directly involved with the admission decision. By guessing around and suggesting theories without knowing what is really happening do not really help anyone and may actually hurt us. Just have faith and be patient.
🙂
Good luck to everyone once again! Tomorrow is another day.
