Not very long and drawn out for me - between assessment day in Dec, Sim, and phone call with the job offer was a total of 14 days. Offered a course iaw my 3 month notice. Everyone's experience will be different, but it happened a lot quicker than I was expecting.
I should have perhaps made it clearer that individuals’ experiences may vary. Some people have indeed moved through the BA assessment stages quite quickly.
I guess my underlying point was that things can and have changed very quickly at BA (sometimes overnight and with little warning) so this should be borne in mind by anyone applying or about to join.
Other than that, I think they’re a good company to work for provided the arrangements suit. It doesn’t suit all obviously.
