Hehe, I remember my Coles group interview... Back in 2007. It was so boring. But basically, they gather you up into a very nice venue (mine was at Gardenhurst Reception), and they go through the name tags, round table discussion, then they put you into a room, and ask you about your applications, when you can start etc...
Then, they called me within a week, I got trained at Coles in Airport West, the first day of training was basically playing games on the register (there was this one question which took an hour to answer... It wasn't long, I just couldn't answer it

Then they put you on registers (I don't know what area you are in, but I was in registers), and slave you away.

I quit within 3 weeks.
But don't let this discourage you, your Coles is probably excellent, with great facilities! My manager was a big meanie
