FA,
Yes as the others said, don't be too nervous. 'Open Day' is a chance for you to find out about the job, meet the recruiters, and ask questions (if you have any). Of course there's also fabulous opportunity to meet fellow cabin crew 'wannabes'... I have made good friends through open days and interviews... it can also be nice to trade experiences of how you went, what type of work you have done, etc etc.
It can also be god to 'settle' you for interviews... you get used to talking with 'strangers' (trust me in that environment you can make friends very quickly he he) and generally get into the group environment before the pressure is on...
If you look at it as a way to meet people and find out about EK, anything else (such as being invited back) is a bonus, you won't feel as bad if they don't ask you back... and you can share stories with others as well!!!
Good luck!!!
