The process consisted of 3 Interviews, all on the same day. One was general and the other two were about maths, split into pure and applied. Overnight accommodation can be provided if you ask for it and live far away. In between interviews greeted by extremely friendly student volunteers who really helped calm my nerves, you can chill with these people or be alone if you prefer.

The first interview was a personal/general interview with future tutor. The conversation was about everything such as: personal statement, extracurricular activities, current affairs etc.

The next two interviews were about mathematics with two people each, one interview on pure and one on applied mathematics. Both take a supervision style format with questions presented to you and then you are expected to work through them, interacting with the interviewers along the way.

I asked a school governer to practice interview me, although it wasn't particularly applicable. I think the best preparation is to expose yourself to short maths you are unfamiliar with (Maybe Step 1 questions, but don't worry if you don't get full solutions straight away), and practice talking through your thinking as you go through the questions as showing your thinking style is more important than getting the right answers.

Smile and be yourself, the interviewers will see your passion for the subject!
