Also had a rejection from OAA this afternoon. The e-mail is generic - encouraging you to apply for further opportunities with partner airlines or training at OAA.
Would agree about the strategies being inconsistent - however, I don't think the end result will be different. If you didn't get in through one school, don't think you would have got in elsewhere. Although days may have been 'merged' at some schools, the background selection process (probably) would have been much the same.
On a side note, it does seem like one of the schools is placing itself as the "chief partner" to BA in this process. I would only ever interpret this as complete and utter tripe. All schools are on an equal footing and any school pretending to offer anything different should be reprimanded.
Congratulations to all those who have been offered a place at the next stage - best of luck to you all. To those who didn't - there are other opportunities out there, perhaps on not such good terms, but if you want it that much, you CAN get there.
