Probably out of date, some might have changed some might not:
The assigned person looking after you will informally ask if you watch Rugby. (cultural fit)
Don't eat the supplied lunch, it always falls apart.
Take some food with you for lunch in case your sim is at lunch time.
Even when when you think you are not being tested you are being watched.
When they ask you questions in the sim while flying, tell them to try later when finished, you are flying the plane. (old boys nz chestnut that one).
Know holds entries, and arc approach distance and times calculations. They get their jollies on those.
Shut down any social media accounts to private if not already.
Watch out for the pilot candidate that makes an illogical suggestion in the group exercise, always one for some reason, can't think why.
