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 was a very friendly atmosphere. My interview mainly focused on personal statement and some reading I had done on the day. Then half of the interview was in spoken French. We went over my personal statement and experiences of the country and culture in general.
I did some Interview practise. I read over my personal statement and made sure I knew the content, then looked at example questions and rehearsed basic answers in French.
Practise papers, grammar book work, quizlet with mistakes
Prepare as much as you can but relax and enjoy the process.
