They only weigh candidates that are usually from an Asian background as they need to be able to lift 28Kg and they can't be underweight.
That is not true. You will be weighed and measured as part of induction. They cannot do it in countries like oz and nz at interview due to discrimination law. If, however, you believe they are not discriminating, you are naive. It is no different to, say, Virgin Blue, who may not overtly be looking at height and weight, but please..............
Something to be aware of: There is no discrimination law here. I know a girl who received a warning during training school for putting on weight. Job ads here are very specific eg. Secretary req. for multinational firm. Indian, pref Arab speaking, attractive, up to 28 yo single....... Get the idea?
