good luck cabincrew boy,
i did a ground interview 2 weeks ago but have not heard any news yet.
the interview was very quick, just 1 hour of company info and then a group activity. your group must decide which 3 pax can fly out of the 5 booked and you all must present to the room who you chose and why. i think the focus is more on who speaks and how, rather than the choices made.
when i went the main positions were for pit crew out on the tarmac not really check in but i hear they multi train you anyway.
let us know how you go.
