2x interviews (one group, one individual); 1x test.
Very specific questions about books I mentioned in my personal statement.
Read a lot; revise the books referred to in your personal statement; close reading.
Don't worry if the interviewers are sounding unimpressed or if you struggle. It might be better than you thought!
Remember this advice isn't official. There is no guarantee it will reflect your experience because university applications can change between years. Check the official Cambridge and Oxford websites for more accurate information on this year's application format and the required tests.
Also, someone else's experience may not reflect your own. Most interviews are more like conversations than tests and like, any conversation, they are quite interactive.
First interview (the college one I applied to) was at Kings College. It was a
My Murray Edwards
I can't remember exactly but they asked very specific questions about books I mentioned in my personal statement so make sure you know stuff you talk about inside out and are comfortable about going into the specifics. For example I mentioned Hamlet and one question was something about the relationships between two of the characters.
I read a lot in the summer before applying and revised the books I put in my personal statement almost like I was revising for an exam on them - I think that and just paying attention when you're doing close reading in class is the most important stuff!
Don't worry if interviewers are constantly looking for and sounding unimpressed or if you struggle - I left my interview convinced it was gonna be a straight out rejection but it turned out to have gone a lot better than I thought it had!
