There were 4 rounds.
1) Chat with internal recruiter to check your values, experience and aspirations.
2) Coding challenge: Test conducted on HackerRank. Not overly hard but wouldn't say its simple. The engineer overseeing the test (Cath) was a legend and made me feel at ease.
3) Execution & Cross-Functional Collaboration Discussion: Chat with someone from a non-engineering team. Expect questions around your way of working, challenges you've faced and how you resolve conflicts.
4) Culture Fit & Team Interview: 2 senior/lead engineers check if you fit their teams. Expect questions about your technical background, your exposure to the technologies these teams use and challenges you've face.
Even though I didn't get the job I walked away having learned a lot and the feedback provided by the internal recruiter (Raisa) was very detailed and will help me in my future endeavours.
