A friend of mine referred me, 1 week later a talent manager called for a quick call of 20'. 1 week later I had another interview with one of partner manager. She was really smart,nice questions, really cool and I appreciated the experience 2 weeks later they invited for 4 interviews in London

Multiple interviews with different stakeholders in the team, some more senior others not so much. It was a bit on the slow side overall, but that's probably the nature of the multi interview process.
