Dr Sandra Fulton, admissions tutor for sciences, who appears in the video said: “The questions we ask at interview are designed to push the candidates and to make them think hard. We would expect candidates by the end of the interview to feel that there was something they haven’t been able to answer.”

Mike Sewell, director of admissions at Cambridge, said that, despite what many people think, interviewers are not looking for a “perfect performance”.

“In the interview we are thinking about whether the person has the right amount of background knowledge for our courses and whether they will be successful in our kind of teaching environment,” he said. “To put it in a nutshell, can they think?”

Interviews for the majority of courses both at the University of Oxford and Cambridge take place from early to mid-December, following an early UCAS application deadline on October 15.

Earlier in the month it was revealed that a record 28,000 straight A students face being rejected by Oxford and Cambridge this year, as many Russell Group universities reported seeing an escalating demand for places.

According to figures, 17,480 students have applied for around 3,100 places at Oxford this year, up 1.5 per cent in 12 months. While, at Cambridge, a record 16,720 applications have been made – up 3.3 per cent.

The record number in applications certainly puts added pressure on those students who will make it through to the interview stage later this year.

Speaking to the Times, Mr Sewell said he hoped the films would “take the mystery out of this aspect of our admissions process and reassure students about what interviews involve.”

However, this isn’t the first time that Oxbridge have attempted to debunk myths surrounding the interview process.

Last year, Professor Richard Prager, head of Cambridge University School of Technology, launched an online question bank to prepare candidates for the difficult entry interviews.

He said he wanted to try and "level the playing field" for hopeful undergraduates.

“Some schools are more experienced than others at preparing their pupils for competitive engineering entrance interviews,” he said. “"I-want-to-study-engineering.org aims to level the playing field by providing a collection of technical interview questions that everyone can use for practice.”

The University of Oxford also released a set of sample questions last year, in an attempt to explain the reasoning behind some of the stranger sounding interview questions.

Questions released included: “Which person (or sort of person) in the past would you most like to interview, and why?” and “should interviews be used for selection?”
