Well, not to discourage you, this is exactly what my professor told me. What I believe is there is a lot of difference between recommending and advocating an applicant? The later is more active and the candidate gets more chances of getting a second interview call. My POI even said that he was really impressed by my CV specially the kind of work I have been doing. But here we go, KAUST decided not to send me an invitation.
What do you mean by: "what terms will the second interview be based on?" Could you be more explicit?
