My interview last week lasted just under an hour. They ask all the standard interview questions really; why do you want to work for flybe, what aircraft do we fly, what is your eventual goal in aviation blah blah blah....not sure if they want to hear certain things from you or if they are genuinely asking for your own opinion.
One thing they said to me though was 'don't be nervous, this is just an informal chat'. Yeah, an informal chat that my career relies on!!! Just so you know.
Good luck!
