3x interviews (20 mins each)
First interview: maths, physics; Second interview: curve sketching, chemical reaction mechanisms; Third interview: personal questions

Be as confident as you can! Be honest and ask questions in the interview.
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.
Arrived evening before, stayed overnight. All food and things provided free. Student reps helped in main 'base' in the college bar. 3 interviews, each 20 mins. Two academic interviews with two academics, one general interview with one interviewer. Spread evenly throughout the day, no additional tests.
Interview 1 - materials and physics. Questions on fields. Mostly mathematical as I've not done physics.
Interview 2 - maths and chemistry. Questions on increasingly complex curve sketching and reaction mechanisms. Generally all content was things I had covered in A-level.
Interview 3 - more general questions about motivations.
Do not worry! Feel confident going in, feel confident leaving. No matter how you felt it went, you cannot predict how you were viewed by the interviewers.
The advice to talk your mind honestly is true - ask questions when you're not sure, and say what you think might be right - even if you're not sure. It might be on the way to the right answer even if it's not perfect. They are searching for raw talent - not refined execution - so
