Even I got this message:-
Status Date 10th December 2015
Status Message We are happy to inform you that your application has been passed on to our admissions committee for an initial review. Once the review is complete, we'll update your status accordingly.They also have asked for the course certificate, about which I am not clear. So I have sent them a mail asking for clarity. At least I consider it "so far so good"!

Perhaps somebody who has been interviewed could share if you also have received some message like the one above?

"so far so good" haha!
Well I will call them up tonight, as I would not want to wait for their email-reply.
Will let you know once done.
For me they have asked just the Degree Certificate, it's actually strange. I mean why would anyone submit the Original Degree Cert at the time of application, had I been admitted it would have been a different situation.
I donot think they'd need your original UG certificate even if you get admitted. They are probably referring to the original transcript as a hardcopy, that needs mailing? Have you mailed/couriered it to them?
