That's true. I don't understand why either. The only thing I can think is unless it's due to people unable to gain the funding after success at the interview.
I know with the airline I work for now (I had to self fund) (not FR) after we got told we passed one person couldn't raise then funds and our start date was then paused till they found someone to make the numbers. Maybe cos it's only a small airline. But it seems now their trying to get rid of any risk whatsoever.
I wish it could be better.
