Wasn’t too gruelling. After initial application there was a telephone interview with someone from the University of Exeter. Super nice interviewer, very simple questions. She threw in a random maths question but it was very very simple, all common sense. Next was AC with group activity and 2 interviews, one 10 min and one 30 min. 10 min was more or less the same as telephone interview. 30 minute was a bit harder - mostly competency based questions and one more technical.
