Wise (formerly TransferWise) was built on a singular, borderline obsessive mission: money without borders—instant, convenient, transparent, and eventually free. Their interview process aggressively filters for candidates who share this mission-driven mindset. Wise operates with an incredibly flat hierarchy organized into autonomous, cross-functional 'squads' (e.g., the 'Middle East Expansion Squad' or the 'Verification Speed Squad'). Therefore, interviews heavily index on 'Impact', 'Customer Focus', and your ability to operate with zero hand-holding. They are famous for their 'Product Engineering' culture; engineers are expected to understand the business logic as deeply as the PMs. They actively select against candidates who just want to write code without questioning the 'why' behind the feature.
