Definitely wasn't the references that got me, I saw what they wrote as it's all computer based. If the system is as you say I would prefer they knock me back far earlier for being borderline... especially as given the gap between my interview group getting our Sim and the interview at HQ was a number of days in which we were expected to be able to just hang around in Sydney
Cost me a tonne of money and I don't feel like they're worth working for after that experience anyway now..
