The interview was quite good actually. I had to trek a bit to get to UTS for a 35 minute interview so hopefully it was worth it.
They take you to your rooms and you meet you interviewer. I had Bonnie from PwC and a man from Ernest and Young. It was pretty chilled - they started by saying how competitive the course is. Something like 400 applicants for 30 positions.
They told me what they did and asked me whether I knew a little about their respective companies. Talked about accounting in a large firm for a while.
Then they went through my applications bit by bit and just talked about the activities that I have done, what I have learnt from it and what I will bring to their organisation if successful. This took up the majority of the time. Id say around 25-30 minutes.
Its unlikely that you will like the interview so much that you will come back for seconds, but its definitely not all that bad.
