I didn't make my point very clear. Most airlines want stable/extrovert. Britannia want s/intravert. I'm not a pyschologist but I think there is some truth in this if you know the pilots, they are a slightly different breed. Of course I can think of some exceptions, I was one for starters.
Not many airlines employ a pychologist purely for interviews like Brits so it must be important to them.
And my point was that Gron-whatever is so nice don't even bother about it, be yourself (perhaps a little less extrovert though).
Just an observation but most airlines like gold stripes, Brits and a few others like platinum. A little understated, perhaps a reflection on what the company looks for? Great company, go for it.
