.....Firstly I don't work for Oxford, but I did do an integrated course there in 1999 (although not the APP)
The key to Oxford is to work very hard and do well in both Groundschool and Flying so as to make it very easy for them to 'place' you with a 'customer' airline - It's all about risk for them if you have a consistently good record in both disciplines then their risk recommending you lessens. They may tell you that it's about the individual and it should be but I would suggest they are results driven firstly because if you fail with an airline they placed you with it's costly for them
Now having said that, joining their APP programme (which I understand is v.expensive) is not the only way to get an airline job. Friends of mine who have airline jobs went to both Cabair and to Jerez and as for me, well I now fly 737-800's after a short stint on turbo-props. So it worked out for us all.
