I agree wholeheartedly with Alison Wolf's view that entrance examinations are a better and fairer way to conduct admissions than interviews. But it's absurd to call Oxbridge's reliance on interviews "arrogant".
Abolishing the entrance examination was the reverse of arrogant; it was a timid, conciliatory, intellectually feeble attempt to make life easier for applicants from maintained schools. Wrong, certainly; arrogant, certainly not.
