After an initial of submitted applications, short-listed candidates at Oxford and Cambridge are invited to a series of tests and interviews with the academics who may eventually be teaching them. Oxbridge interviews have acquired something of a mythical status in the British media, becoming a source of various humorous anecdotes and urban legends due to the perception that the interviews themselves are bizarre, intimidating and/or frequently involve unusual questions and requests. Interview prompts reportedly used in the past include ""Do you think you're clever?"" (from a Law interview at Cambridge) and ""Talk about a light bulb"" (from an Engineering interview at Oxford). Admissions staff have said that there are no correct answers to such questions, but that applicants are assessed on their ability to approach unfamiliar, open-ended problems and discuss them articulately, incorporating new ideas and evidence as the discussion progresses. Candidates are also expected to show a willingness to challenge their own preconceptions about the topics under discussion, as well as the preconceptions adopted by their interviewers. This is essentially a test of whether the student would do well under the tutorial/supervision system at Oxford and Cambridge, and a poor performance at interview may negate an otherwise strong application.
