4 steps including a meeting with CEO. I went through 3 rounds, a cultural interview, technical and a meeting with some managers. The interview process was very slow. I think my 3 interviews occurred over 4 weeks. No contact between rounds except for scheduling meetings. They use a cool virtual interface called gather for meetings which is sort of like a little video game. The 3rd meeting seems very much a vibe check with very vague open ended questions. The questions seemed very focused on your experience and aptitude in working in an ever changing vaguely defined environment.
