It's important to think aloud
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.
There were two interviews. The first one was with the admissions
General interview: discussed some things from my personal statement (e.g. work experience). Then we looked at some material that was in the field of the interviewer (archaeology and anthropology). Discussed some maps on old English settlements.
Geography interview: had to read an article about geoengineering and then answered questions on it, including doing a summary of the article. Then looked at some graphs and had to answer questions on them (e.g. about trends).
It's hard to do your 'thinking aloud' but important too, so the interviewers know that you have ideas and aren't just blankly staring into space
