Oh, shock horror. A Cambridge University admissions tutor has admitted to looking at prospective students facebook public accounts.
The University says it relies on "interview performance, academic record and personal statement, outlining their interests and reasons for studying a particular course."
But someone can be nervous at their interview, or overstate their interests in a personal statement. Or they could be very, very dull and do nothing but work (while I like to think of City boys as being very, very dull, nowadays they like to recruit people who get firsts while, say, captaining the rowing club).
Perhaps the tutor doesn't really want a bunch of dry, grey, faceless academic clones who can do nothing but work, because if you pick that you'd get a bunch of nervous breakdowns long before the finals. I suspect the tutor isn't using this as an excuse to deny people, but as a clue that someone should really be let in.
