Hi everybody
I had a skype Phd interview last week ...today i recived this email from the project first supervisor :

Thank you for your interview last week in regards to your studentship application. We are still processing your application and The Graduate School will let you know soon about the result of your application

anybody have any idea what this means ? i am so stressed ....

It means... they haven't finished processing your application yet and will let you know the result soon.

i was wondering if they came to any conclusions ? or they have some applicants but no potential candidate ?

It means they haven't decided yet, still considering the application. These things take quite a while once the interview is done, and even once the decision is made.
