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.

Started with some smalltalk and basic questions about something I'd written on my personal statement to break the ice. Then in the first interview (human geography) I was shown some prompts, a map for instance and some photos of different things and was asked to speak about what I thought they were showing, how they were geographical and why they were interesting or relevant. We then spoke about areas of geography I was interested in and if I was passionate about anything in particular and continued discussing this topic at length. The second physical geography interview was graph based, looking at correlations and data on natural disasters which I were asked to interpret and discuss, particularly in regards to policy.
I carefully read through my personal statement so I was familiar with the things I had said and spoken about. I checked the news on the day and tried to keep up with interesting geographical stories especially in the week before the interview, as well as just reading books and articles and watching documentaries that genuinely interested me (they don't have to be super academic, so much better to be genuinely passionate about it).
Practice papers and practice essays, which are available online. Especially working on timing as you have to be quick.
Be yourself! It's OK to be nervous and the tutors interviewing you will understand but just stay calm and talk through your thought processes on things. If you don't know the answer, don't be afraid to be wrong, just explain why you've said what you have. Being friendly also goes a long way. The interviewers are just people at the end of the day and they're not trying to be mean or intimidating. You can do it!
