Christ's College Maths interviews

Hi everyone,

I’m applying to Cambridge this year for Mathematics, and I’ve been invited to interview at Christ’s College. I’m an international applicant, and English isn’t my first language, so I would really appreciate some advice from people familiar with Christ’s interview style.

I’m mainly wondering about:
What are Christ’s Maths interview questions usually like in terms of style and difficulty?
Any noticeable differences compared to other colleges?
What kind of thinking process are they expecting us to show?
Common pitfalls or things to avoid?
How should I best prepare in the remaining time? Which topic should I focus on?

For context: I’ve completed A-levels (4A*), and took STEP this June (S, S).

Thank you so much in advance for any advice or experience you could share!
