I can understand frustration, but to come out and say that the airline treats people like crap is going a little far, and does come across as being quite immature.
I too didn't get through the open day, and although I was upset, it doesn't change the fact that I really want the job and respect the company!
To do the job, you need to be level headed, and from first impressions, it doesn't seem like this person is!
Barrett - if you don't get though the open day, you don't need to wait a certain amount of time before trying again (that's only if you get though to an assessment day). It seems that EK come to Melb every 3-4 months, so try again next time!
