Pergunta de entrevista da empresa Booking.com

The questions were mostly applications of basic CS stuff (algos and data structs). The hardest was the system design/architecture interview question. Frankly, if you don't have web dev experience, especially with large scale apps this is tricky to even revise for. The task/question I got was to design a critical component to interact with another service. The hard part was error handling/failover and maintaining consistency.
