Made it to the final stage which is accensement center. Video interview was largely competency based, no technical questions about coding etc. Numerical test before the video interview was quite challenging.

Interview process consisted of behavioural questions, then hackerrank leetcode-style questions, then an in-person assessment centre. Behaviour questions were standard. Leetcode-style were at easy and medium difficulty. In-person assessment centre consisted of two separate interviews. Both interviews asked questions relating to times I had worked with large datasets, and how I would approach things in a privacy and security oriented way. At the end I was asked a tricky system design question that I don't think I successfully answered.
