Was put in a room with about 5-6 other people in it. Spent the first few hours getting to know each other, learning a brief bit about the job and the roles. We then had a tour of the office building, and then we were taken to a separate office where we had a english and maths test. If you pass that, you then do a team activity where you have to do a sales pitch. Once this is done, you fill in a form and go for an interview. One all this is done, you're free to go.
However, be prepared that this is a surprisingly long interview process that does last for a good few hours.
