From the BA FPP website:
"The Selection Centre
Your FTO will send you details of the date and time of the selection centre- these selection centre days are planned throughout March 2015. Here you will undergo a series of tests, as well as a group exercise and interview, to assess your ability to complete the arduous training course ahead.
British Airways Recruitment Centre
If you are successful at the FTO selection centre then you will be invited to the next stage, which is a further testing day at BA. This will be arranged during a 2-week period, which is currently planned for the end of April 2015, at the British Airways Recruitment Centre, Waterside, near London Heathrow Airport.
If you are successful at BA testing, you will then be invited back, on another day, to Waterside for the final selection centre. Here you’ll have a chance to meet and be interviewed by British Airways pilots, and be further assessed for your suitability to join the programme."
