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.

1st interview - I was given an equation and told to solve it, then given a different one and told to give the approach on how to solve it. Then they gave me a problem sheet relating to graphing.
2nd interview - I was given a situation on buoyancy and told to explain what would happen in the situation. They prompted me a bit. Then I was given a chemical model and told to make some calculations from it.
I read books around the subject and previous interviews for other universities also helped me.
