From the Oxford Website:
You will need to complete four questions via our online assessment platform.
To virtually meet you, get a sense of your personality and see how you think on your feet, you will need to complete an online assessment as part of your application:
Two motivation-based questions - all candidates will answer the same questions
One competency-based questions - this will be randomised
Written response - this will be randomised and light-hearted to show us how you can think on your feet!
