I also got the interview letter today and the interview is scheduled to be next tues sep.28. we are christian and i handed in application form on sept.8 (the day after the info session.)
My girl had interview on 9/28 and she said the lady who interviewed her wore many many clothes!!! Don't know why she said that but i will definitely put on long sleeve for her as it seems a more "proper" dress code. I saw girls with not even sleeveless "背心" but "吊帶"!! i personally think it is not that suitable lor.... We parents have to wait outside ie. no air conditioning. hope it helps.
