Well I think some of the group interview techniques used for cabin crew are a waste of time. It's an un-natural environment and everyone is feeling nervous so it's hard to behave normally especially with accessors watching you. If you know what thay are looking for it's easy to play the game especially if you strike a happy medium. I'm sure even with faar_canel's aggressive attitude could manage the challange if they tried - not saying you'd want to but do you get my point? I have been an assessor on group interviews myself and seen how assessors have different views on the same candidate some like them/some don't...it depends who you get on the day!
I'm sure we have all been disappointed with the outcome of an interview before now and if you haven't then your day will come - let's hope people will be sympathetic not pathetic - mentioning no names!!!
