ok well i had my initial testing today in sydney....it's been a long day, i'm back in brisbane now.
i don't know if the testing will be the same between australia and uk, but mine was divided up into 3 parts.
1. Interview (45mins)
2. English Test (1hour)
3. reasoning Test (45mins)
1. Pretty laid back, they get you to talk about yourself and they refer back to your application alot. When you arrive at the very beginning they should give you your timetable and an introductory brief. Read it as many times though as you can before you get called, because they ask questions from it.
2. Not very hard at all, just listening to a CD for the first part and ticking what you think you heard. Second part is a grammar test.
3. Reasoning test is completely those shape matrices things. 48 of them in total, can be quite stressful when your doing it.
That's all I did, no medical. Return of service is 7 years in Cathay if accepted.
I find out in 7-10 days if I win my free trip to Hong Kong
Hope this helps =)
