I think it depends on what kind of kid they are. For my girl i think it's more harm than help. I've tried to put her in the interview class for a month and found she answer less after attending the class. I think coz she's being asked the similar question for too many time and she starts to refuse to answer any question from adult even her name. then i stop her class immediately and try to train her at home by myself and the situation improved a lot. Of course the performance of the interview really depends on her mood on the day - she's some interview with very good performance (sit still and answer all questions) while some she even cries to leave. so i think what's more important is the time slot of the interivew and try to avoid more than 1 interivew in a day as she usually screw up the interview in the pm. Well having said that, it's really depends from kids to kids. I know a fren's son who has no interview class at all but has 8 offers (mostly from brand name kinder or dragon school) and another fren's daugther having interview class but got all waiting. Just do not put too much pressure on the kids. good luck!
我試過sit in 某間名司儀開既教育中心既面試班,嚇死我!個老師本身自己英文又差又有accent, 態度又嚴肅又惡。全班6個學生,個個輪流出去同老師單對單"interview",每個大概8分鐘,其餘時間都係各自各填顏色。我覺得建立小朋友既自信心最重要,上填鴨班只會令壓力增加,standard question and answer問答機械化。其實我真心覺得用咁短既時間interview咁細既小朋友係真係好唔公平,奈何香港既教育制度係咁⋯我自己就在interview 前盡量令小朋友輕鬆,希望佢做番自己,平時既教育與交流最重要,上堂谷行個小朋友我真係一D都唔buy
