I applied in-person. The process took 1 day. I interviewed at Growth Street (London, England) in Apr 2019

A good mix of technical and cultural questions, followed by a casual conversation about the business and engineering challenges with CTO. Technical part was with a team and involved design and implementation questions of a real problem of designing a system.
