inandantia,
like a few of the members, ive been to the odd one or two open days, and i cant remember any weight testing being done at all.
the only time it might become and issue is if you really look unhealthiyl skinny, or when you get your medicals done and they weigh you then.
if thats the case, the week before, just spend everyday at your local macca's :P
letmethink, during the 2on1 interview, i get so caught up worrying about my answers and my bodylanguage and even trying to analyse what the interviewers are doing after each one of my answers, i tend to forget about being me! i turn into some statue-esque (no nervous jitters...CHECK!) monotone machine, and dont make any jokes or show anything like that. i really hate those interviews, i'd like to calm down, but it never works
