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.
2x30 min interviews: 1 technical interview on mostly maths - 2 interviewers & 1 open interview about motivations with some physics theory - 1 interviewer.
I also had 1 computer based multiple choice question
Complex numbers, Archimedes principle, Newton's laws - conceptually challenging.
I did the IB so my syllabus was quite different to A level so there was some content they asked me that I had not learnt at all [Editor's Note: if the interviews seem to assume you know something you don't, let them know you've not covered that yet - they understand different curriculums cover content at different stages].
