Yes I have been looking at this thread for any info as well. I had an interview with JAL last october very interesting it was too. Everybody entered a room and there was a JAL member of staff sat at the end of the room. I was very chatty and to be honest im not sure that worked in my favour as i am now pretty sure that she was taking notes on everyones behaviour. I cant believe she was dealing with applications for 5 or so hours. Anyway everyone was called into a room in groups of 3 and interviewed just a basic conversation about yourself etc. Then after an hour or so people were called in to a room in groups of 10 or so. If your name was on a whiteboard then you were through to the next stage. Luckily mine was and I was invited back for an interview in the afternoon. Before that interview a few of us had our grooming standards check they looked at our nails and checked our hair etc. After that those remaining ( about 15 out of 50) had a 2 on 1 interview that was quite scary and my interviewers really tried to pull me apart on my life when i was living in Japan. After that I was told that I would be contacted in 2 days. I unfortunately never made it to the final interview. Overall a very interesting interview looked to me that eu citizens with one or more languages had more of a chance but i cannot speak any eu langauge but still made it further than most. I did hear that only one person made it through to the last interview from the day before, so i think very tough but great experience. I hope this helps.
Take care and good luck
