In the initial interview (30 min on the phone), the questions were relatively standard interview questions, about why I was interested in the work, relevant work experience; also spent time describing their work and philosophy and the role itself. The 2nd interview was 1 hour (or even a bit longer) via video chat with 3 employees. This was much more extensive, asking questions that required more critical thinking; the goal of these questions (I believe) was to help them understand my thought process and who I am as a person, to see if I would be a good fit for the role.
