We were all told that we were borderline pass, only having to resit one thing or the other. Apparently you were only invited back under those circumstances, if you failed everything then no chance. I think that was mainly an A320 thing though when it happened. One of the gents from recruitment happened to tell me during lunch on day two that of the people who had been invited back, not that many had managed to pass second time around. Whether that's true or not who knows?
