Hi Airhostess dream...
If you read through all the posts most of your questions should be answered. I read them all before my interview and i got the job!! As you read through there are updates on how the interview process has changed, but to be honest its not far off the first post which explains everything. Also i thought i would get weighed and my height checked, but on the day neither of these happened so i suppose they also change the format slightly depending on whos recuiting!
Best of luck tho, and my top tip for you would be SMILE... lots!!
