ek interviews
I too went to the open day in sydney, it was crazy as too many ppl turned up, I went back during the week, got through the entire day and got a final interview in which i attended a week later.. I got the job and cant wait to leave.
I believe they do have age rescritions however they cant discriminate so they say they dont, that is why they will not tell you why you have not been successful.
The ideal age is 21-23, if you get in younger I believe you would have to have a strong customer service background and been in your current role for a while to show stability and maturity.
Your cv should be simple and easy to read, they get so many cvs they dont really care about how "fancy" it is just to be professional, also your photos should be professionaly done as this shows you are serious about getting the job.
During the assessment centre keep open body language, dont cross your arms or legs, and SMILE, make sure you give input into the group sessions, and encourage and compliment others on there good ideas.
This is just my opinion and advice I got when I got from friends who work up there, take or leave it but it worked for me.. I got the job..
