I was reffered by my friend. After this I had a short call with HR and I've been asked to upload my CV in the Workday. The second round was with Hiring Manager (in my case also Engineering Manager). Then I had an interview with potential teammates. And in the end I had a call with the head of department.

They sent me a technical interview but they did not ask anything. They just did chit chat and ended the meeting. I did not understand the purpose. I think they did not hire and just collected cvs.
