There is no such thing as a typical BA employee, we are diverse. QF, it seems, however, from my experience, would like their employees to be stereotypical. (Noitice there I said," in my experience.") You are all getting far to protective and touchy about what was an honest peice of personal feedback.
I went to the interview, as a number of people did, to gain experience (never too old for that) and to hedge one's bets. But I don't have to qualify my actions here. It paid off for me, and each to their own. I don't generalise, but from a few QF people whom I have spoken to privately, there does seem to be a little unrest. (Not just cabin crew. I have worked closely with QF staff on the ground.) In the world of avaiation, this is not uncommon!
Since I have nothing whatsoever to do with QF, I have said all that I have to say on the subject, which was interview feedback. From the PM's I have received, I know that a lot of people were grateful for it.
