I had one interview with the CTO followed by getting a bunch of tasks that I had to do prior to the second and last interview that then was with 2 people from the team.
Where the first interview was more informative and great to get a feeling for the big company picture, the second one with the team focused more on the tasks I did and getting to know the team as well.
Both interviews were very relaxed, while including role relevant and tech specific questions and helped to get a good overall expectation of my role.
