as I said I had my interview last year for deferred entry but I can tell you what we had. First you have numeracy and literacy test, then after lunch, providing you passed those two, they showed us a short film. We had to watch it and then we had a group interview ( about 5-6 people in a group ) where we had to discuss what we watched, they were assessing us as for how well can we work in a group, speaking , listening and understanding. you need to make sure you speak but at the same time don't be overpowering and let others have their say.
After the group interview we were called one by one to the room where we had about 10-15min individual interviews
