Yeah, I‘m also an international student, from China, actually. I also got the same response as you got about the admission interview. But I received a call from them on March 9, which is really unexpected. I didn't prepare at all. So I'm guessing I messed it up. A little bit freak out now.
It is Emly Mcdiarmid, the director of admission from FES that told me the result will come out in the early next week.
Good luck to you!
