I was invited to an assessment center where we first had to do a programming and probability maths exam. After this we had a 1:1 interview with a member of the department where we were asked about our answers and got asked more technical questions to do with general computer science knowledge. Afterwards we broke up into groups and had to discuss and present about a case study which was then followed by questions. The final interview of the day was another 1:1 where we were asked general interview questions.

I applied through the company website and got an invitation for a Pymetric test which I passed. Then I got an email to ask me to do some questions on HireVue and record my answers.
