The "Captain in a nice dress" question is actually used to test your pre-disposition to sexism and underlying attitude to female pilots
the rationale is that if your instinctive reaction to a "captain wearing a dress" is that it is a bloke wearing a dress
,......... and the alternative thought that the captain could be female and thus normally "wearing a 'nice' dress" does not cross your mind,........ your name might contain the words sid and sexist
Here are a couple of BA favourites;
HAve you ever flown with a Captain with Conservative / Liberal attitudes? How did you deal with it?
A guy I know spent so long trying to work out what they meant by conservative attitudes, he did not even hear the rest of the interview questions they asked. Lets just say, he is not working at BA at the moment!!!
