I know the questions are asked, but again, it's the difficulty of getting people to answer those questions truthfully and honestly, at a time in their lives and their careers when there are probably quite a few other pressures on them, such as where they're going to live in the future and what job they're going to do. How much attention they give that exit questionnaire, I think, is questionable. Without making it compulsory.... Getting honesty in those responses is something we're trying to achieve.
