2 x 25 minute interviews. First one about chosen topic. Second with harder maths questions.
Derived an acceleration equation. Force / time and acceleration / time graphs.

Be enthusaistic! Your results can also show your academic capability. The interview is a chance to get to know you.
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.
I stayed over at college the night before as I had early interview slots, and on the morning of the interview was directed to a hall where everyone was waiting. It was a very chilled atmosphere and there were college students around who were happy to answer questions. I was then taken to my first interview in which they asked me some questions about my personal statement, some questions on my specialist subject (they email you beforehand with a list of topics and you choose the one you want to talk about- mine was electric cars but it was very chilled and they asked fairly simple questions) and a final basic maths question. It lasted about 25 minutes.
I then returned to the waiting room before being taken to my second interview which was formed of two maths questions- both of them mechanics. Although they were on concepts we’d covered at school, some of the ideas were fairly complex so a majority of my answers were guesswork and they had to talk me through some parts. Again, it lasted around 25 minutes. Both interviews were taken by two people.
All of the questions were mechanics based. In the first I had to derive a fairly simple acceleration for a specific sliding block scenario which was fairly straightforward, the second involved drawing the force/time and acceleration/time graphs of an unusual projectile situation which involved a lot of guesswork and the last was about energy and acceleration of a situations inside moving vehicle, which again involved a lot of guesswork and being talked through.
The best preparation I did was going through the questions on a website called ‘iwanttostudyengineering’ (inventive name I know) as they were of a similar level to the ones I was given in my interview and taught me how to approach that style of question. Also making sure I had a good understanding of all my A-Level course material was very helpful.
Just remember to be really enthusiastic as at the end of the day it’s your results that show them whether you are academically capable of the course, the interview is just a way of getting to know how you work through things so don’t stress if you don’t get the questions right.
