Keeping a healthy mindset.
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.
Two interviews approximately 30 mins each right after each other in the morning. First was History of Art centred with two related interviewers and the second a ‘general’ one with a maths professor.
Subject based one asked about essays I’d submitted and my personal statement as well as some unseen paintings. Felt like it went ok but not particularly challenging which I was concerned about afterwards.
Second general interview was quite random, discussing why I wanted to do History of Art, choice of college etc. Again felt ok because it was quite a causal chat but didn’t think I’d seemed that intelligent or shone particularly.
I did some general subject reading including more in depth research for the topics in my personal statement and submitted essays. Looked at the university reading list I think and may have read some of the recommendations.
The most useful things were general practice interviews to practice keeping calm and talking under pressure.
Whether or not you get in I think having a healthy approach and appreciating how lucky/contingent admissions are is something to keep in mind.
