my apologies for the late reply, as i'm just reading this,
if u still haven't taken the test:
personality:
no way to prepare, simply selecting words that describe u from a long list (e.g. joyful, responsible, respectful, )
and that describe xstics your colleagues should expect from you
logic:
(timed, 12mins?)
questions u see in IQ tests, maths and english,
e.g. "which word does not belong to the group? head, hand, foot, bed" - (questions aren't this stupid though

)
sorry for the late reply! if u've had the test, let me know how it went.
Did you apply for a position? or for one of the educational programs?
