There were 6 of us attending on the day and the process consisted of a group task followed by numerous individual stages. There was a mathematical task and an face to face interview. Overall interesting process and carried out well.

Applied through an interviewer. Relatively simple process, just submitting a CV and having only 1 interview. In the interview there were 3 parts. I had some pretty normal competency questions, a fairly simple 15 minute mathematical test and a chance to discuss more about the role and the company which was largely me asking questions and was really useful. Heard back about a week after the interview.
