Oxford - Maths vs Maths & Computer Science Interview

What's the difference between a maths interview and a maths and computer science interview at Oxford? I know the MAT is very similar (only one question changed).

Most colleges give Maths & CS candidates two interviews: one from Maths tutors and one from CS tutors. The CS one will tend to concentrate on areas of Mathematics that are more relevant to CS, namely discrete mathematics, logical thinking, and algorithms. There's not really a huge difference between them.
