Recruiter contacted me and sent me an online challenge (algorithms and stuff). Then I had a take home project followed by a technical onsite interview with some of the managers. I had a callback for final interview with HR.

I did a test task before the interview. Then I had two interviews on the same day, technical and HR. Very nice and welcoming people. We spoke freely as friends. They quickly answered in a couple of days. From the first days they immersed me in the atmosphere of the project.
