Three steps: a phone screen to learn about you, a coding challenge to assess your skills. Its a toy robot challenge, and a behavioural interview to explore how well you will fit into the team.

I don't recommend applying if pair programming as a daily practice is not your cup of tea. Round 1 - 30-minute recruiter screen Round 2 - 90-minute pair programming with two senior engineers. Extend toy robot simulator in language of your choice. They give you the Github repository link just before this interview. Round 3 - 60-minute team match I was told that the only negative feedback for me was that I was iffy on daily pair programming when asked during team match interviews. On reflection I like pair debugging for difficult bugs/problems, but I don't think pair programming everyday for routine and straightforward tasks is a good fit for me. I also personally think the codebase I was given for the technical round (round 2) had quite unorthodox code style, and there are cleaner ways to structure it.
