Interview
I applied online and got the online assessment.
There are several stages
1. famous 80 in 8, I did 69 correctly and moved on to next stage
2. Games, ballooon pumping game & sausage flipping are the hardest, others are just reaction and memory
3. Sequence reasoning, find out the next number in a sequence (quite hard, make sure you knnow the common ones and the mixture/variations of them)
4. Rapid fire probability questions (+1 for correct and -1 for wrong answer, I think 7 or 8 out of 10 is a pass)
5. Personality questions, there are wrong answers be careful

I got rejected after the personality questionnaire (OMG, or maybe just my overall score is not high enough)
Interview Questions
Rapid fire probability questions, there are traps, be very clear and quick, you have only 90 sec each
