"do you know if they get to any online tests prior to coming into the assessment day?"
Marly last time I applied for Perth base they sent me thru 2 online tests (I think one was the usual Hogan's but the other was some random assessment from the UK - I struggled with it @ first but then I got the hang of it) Then If successful they e-mailed me invite to assessment day - only got 2 days notice which was why I didn't attend which is why I had to re-apply. Hope that helps a bit???? Which is basically what tashhopeful said
