The most baffling thing from this topic is the number of people who expect Oxford to find them all a job, and the phone to be ringing to them every minute. If you thought that would be the case then you clearly didn't research enough or listen at an open day because they never ever promised that. If you're going to be a professional pilot you should be able to use initiative and make things happen for yourself. This can't always happen to everyone, so explore both avenues and hope for the best.
And also why should Oxford not use the statistics when you get a job yourself? How does anyone know whether being from Oxford helped you get that job or not? At the end of the day, if you went there and you got a job you got it because you had been trained to sufficient standard, and they provided that, so they should be able to use it as a statistic.
