hey i had an interview for midwifery at surrey back in november and got a conditional offer from it. The maths and english are easy. It's simple mental maths with working out percentages and putting fractions into order etc etc. With the literacy you get two things, the first a section where you have to circle all the gramatical and spelling mistakes you can, the second was a scenario between 2 nurses talking and you have to interpret what they said and say how you think they felt and what you would do in that situation.
As for the interview, they are really nice. The only complaint i would have is that they didn't give us a specific time. I ended up being the last one and so was sat around for hours and we didn't get lunch.
The people I had interviewing me were very nice. They asked things about my extra curricular activities, what makes me better than all the other people applying, what i have already read up about the course and how i found it out other than on the surrey website and soemthing that's affecting midwifery in the nhs right now that i would change (I recommend reading the british journal of midwifery for the last 2 questions)
Anyway that's about it hope it has helped.
Good luck with the interviews! xx
