lol koma.. your interview sounds different to mine.
My officer was Dale Anthes.. he was young and heaps nice.
As soon as i entered the building.. there were a bunch of people waiting in the lobby but I just went straight up. Some lady greeted me and told me to come this way and lalala. So I'm assuming it's ok to just go straight up.
30 second speech - i didn't plan mine at all, just said what came to me at the time. And we didn't talk about work experience AT ALL. Everyone talked about school, uni, family, sports and favourite movie. Actually, we were told by Dale to say our favourite movie as an ice-breaker.
We didn't even have that "O" for Opportunity thing lol.
