I've applied in November for the Graduate program and was contacted in February. Once I have been engaged in the process, it didn't take more than 2-3 weeks. I had to perform the video interview with some formal and some informal questions, but overall I believe that they were looking to assess the candidate's personality and if he can think outside of the box. After this, I was invited to take part in the assessment centre where each candidate had to take part in group exercises and also individual ones. It was challenging, but if you know what you're doing and did your homework, it's going to be quite entertaining.

One sided interview, questions about how you would act in certain scenarios along with business logic and general logical thinking/reading comprehension. Nothing relating to specific technical roles so I recommend looking into how these processes normally ask questions.
