When I attended second stage BA some years ago all I saw throughout the interview was the top of the lady pilot interviewers head!
She had given me the preamble that I shouldn't worry if she was writing while the other (HR) lady was asking me questions. She then continued to write while asking her own questions. Her interview technique was atrocious.
I, like most people, have attended a reasonable number of interviews over the years and have been successful in about 75% of them. This was the most poorly run interview I have ever attended.
Perhaps I was just unlucky with the individual who was doing the interviewing. Needless to say I did not get through second stage.
