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.
I had two interviews - one college interview in the morning with the Arts and Social Sciences admissions
In my college interview, we mainly talked about my personal statement, especially a specific book I had read. We also discussed my motivations for studying the subject. Finally, we turned to the reading I'd been given, and discussed the underlying ideas behind it. This interview mainly felt like a nice chat, although since there was no table between me and the interviewer I was quite aware they could see my hands quaking!
My subject interview was more challenging - we warmed up with a question about visiting Japan and moved onto discussing bias in history. We briefly discussed language, and my learning of Chinese (which I was studying for A level). Finally they asked me about my extra curriculars, which threw me a bit - I assumed it wouldn't come up, and wondered if they'd already decided to reject me! But it turned out all right in the end.
Honestly I didn't really prepare that much, other than going over my personal statement and re-reading a book I'd mentioned but couldn't remember that well. I had done some preparation for language-based puzzles too, such as the Oxford OLAT admissions test, but I ended up not needing it (although others had language based tests so I suppose it varies). It was helpful to use "The Student Room" to find fellow AMES applicants though as we could support each other through the application process and share any knowledge we had, which is especially useful for an obscure subject like AMES!
