I think it’s as fair a process as possible and fairer and more transparent than most unis.
By the time someone gets to interview, they are already ranked. Their admissions test (if there is one - and if there is, it’s a good thing) and submitted written work and GCSEs (contextualised) and predicted grades have all been factored in. Those low down the rankings have to do more in interview to rise up the rankings and beat those who were lower down. It doesn’t just come down to interviews and they are at pains to say that. But often people imagine they start the interview in the same level as everyone else, it forget they don’t. Some are already ‘favourites’ and others an outside chance. And I think that’s right, as interviews do have a subjective element to them, and as has been said on the last couple of posts, different interviewers might like different answers and the questions themselves might suit one candidate rather than another. However, the admissions test marked centrally and other data analysis is more objective. The combination of the different aspects and the transparency and publication of data such as average admissions test results to get shortlisted or to get an offer make it all a bit clearer.
In the end, the interview will swing it for some candidates and go against others, but much if the rank order is already decided and it’s already clear that some will very likely get. A place and some won’t. As has been said, those in the middle are where the battle lies and where the litttle things and flunky things might make a difference between getting one of the last places or not.
It’s hard if you find out your admissions test score was very high, you written work ranked high and it was the interview that let you down. Perhaps it’s easier to take if you get the feedback and find you were always low down the ranking in all aspects, although good enough to get to interview.
In the end, I think the answer all those rejected need to hold onto is that they are very good candidates and all who get to interview are strong. But quite simply there are too many good candidates and they couldn’t give everyone a place. It doesn’t make them a poor or weak candidate. And these students are those who are likely to go onto get good degrees from other top unis. Beyond that, other stuff is important to like personality, character, team working, seizing opportunities. Some Oxbridge people are good at these and others aren’t and likewise some from other unis will be better at these. Lots of things will determine outcomes in life and Oxbridge is just one very small part.
