Continuing the trend, Wadham's questions:
Politics (2 tutors)
Tutor 1: What do these parts of the UN charter mean, do they conflict, why do they conflict, what's wrong with the Security council and how would you reorganise it?
Tutor 2: On two desert islands, people use carrots as currency. One island has an equal distribution of carrots, and on the other, Alice has 3, Bob has 2 and Clare has 1. Is this fair? What factors affect fairness &c &c.
In my second interview (Philosophy and Economics), I was asked the million-dollar question: "Why PPE?" The tutors then belittled part of my response ("... and I love studying Maths-y subjects and humanities, and I want to carry on" "So, you're coming to us because you can't choose, then?"), which I then defended. ("No, I'm coming to you because I want the best of both worlds.") I was also asked about what books I'd read around my subject.
What would you like to talk about (Existence preceeds essence). Define that. What about this? Or this? Now look at these logic questions. If all As are Bs and all Bs are Cs, are all As Cs? Continuations of these.
When it comes to health, there are high risk people and low risk people. If they get ill next year it costs £10,000. How much should their health insurance be if they don't know what risk? What about if they do? How can health insurers attract low risk customers if they know they're low risk?
Nothing in my submitted essays was discussed, although admittedly, they were about Far From the Madding Crowd and Witchcraft in Early Modern England and therefore totally irrelevant. I never had any evidence that anybody had read my Personal Statement, either (although I'm sure they had! They just didn't ask me about it); I did, however, get asked about what I'd read seeing as I wasn't studying any of the subjects at A-level.
The only other notable thing about my interview was something of a "good cop, bad cop" strategy between the two- The politics tutors were incredibly friendly and welcoming, whereas the other interview was distinctly cold. This could be luck, or a deliberate strategy- I should think different people perform better under different conditions, so if they give two different situations they may get a better impression of your overall ability. But this is all just idle speculation.
