There was an Online Assessment which consisted of two Leetcode easy questions. Can't remember which ones they were but they weren't too difficult.
After that, there was an Online Personality Quiz. Basically a lot of statements, and you have to choose whichs one you relate to more.
I passed those, and advanced to an online interview. It was with two engineers, asked a bit about me and asked me some technical questions. Didn't have to code, but needed to explain my train of thought & solution.
The final interview takes place in their offices. It was a 3 hour assignment, and if you passed that you have a 30 min interview with the Head of R&D.
