What kind of thing they did in group challenge?
Do you know what the roleplay like??
Do you know if they check his unaided vision?
And did they really send him to the pool and check how fast he can swim?
I can swim but I can't really say I am good at it...so.
The group challenge was where they were given the scenario of a train needing to transport 15 passengers but there were only seats for 10, and you have to pick who will have to wait for the next train which might be a hour later. My friend said something that it's better to go with elderly people, or sick etc because they need the most care.
Roleplay was something as simple as someone playing a passenger who wants to get out of his seat while the seatbelt sign was off.
Eyesight will be checked in his medical. He also had to go to his local pool and get a swimming instructor to sign off that he could swim 50 metres and tread water for 3 minutes.
As far as I know, while I know it can be a different length you need to swim for different airlines, you don't have to be swim fit. If you can do what is required of you, that is fine.
Happy to help
