1) introduction call with engineering team lead 2) take home algorithm tasks without time limit 3) live technical interview with 2 engineers 4) calls with CEO and CTO 5) offer From my experience it was a fair interview which covered most of the things needed for engineering position. I gladly accepted the offer after I received it.

First, I had to pass a test that consisted of standard engineering tasks (algorithms). After that, I had a series of interviews with future team members that I would work closely with. The interviews had a casual tone with occasional engineering question. There was no need for special preparation.
