well i hope those info helped u
i m not quite sure about the interview in EUrope but it is very tough and i dont think they employ many people there remember it is a JAPANESE thing

they would rather employ the japanese speaking people instead of .... u know
but then german speaking could be an advantage if u wanna work in frankfurt believe me , asian airlines r dying for the German market

as well as the german speaking staff...
but i m not sure if JAL has their own staff in FRA or ....because for example..ANA ( all nippon airways ) is a star alliance member and it is even BIGGER than JAL in japan ( believe me it is true )
in FRA, they only use Lufthansa as check in staff..very very very very very few ANA staff..if u know what i mean
JAL is very picky!!
male crew..mmm..JAL is a very very traditional airline!!!!!!!

they always think the one to serve people should be FEMALE
and during the JAL interview in hongkong..they chose only those who 1) could speak fluent japanese 2) very tidy and clean 3) all females
also they really concern the very very first impression. even for me, i speak fluent english, mandarin and cantonese also i have years experience working at the airport related to airport and airline operations...i was not chosen
if u want to know more add me in ICQ 3810001
or pvt me

cheers
