The following passage appears in BA's FPP website:
Honesty and Integrity
British Airways places high importance on honesty and integrity within its recruitment processes. Whilst we appreciate you may want to discuss your application with friends and family please do not share the details of your application and any subsequent assessments with others, especially those applying for the Programme. Sharing details may compromise the fairness and integrity of the entire selection process. Furthermore, it could advantage other applicants and potentially disadvantage you. It may even disqualify you from the selection process..
Please do not share details of your application with others... especially those applying for the Programme...it may even disqualify you from the selection process."Sorry if you think I'm a pedant but you WILL be assessed on your ability to carry out simple instructions if and when you get to the BA assessment stage!
Oh, and BitMoreRightRudder is 100% correct but for some of you it may already be too late.
