Previous work experience, distributed systems, some javascript questions from older versions of ES which you may not even encounter in day-to-day coding. System design question and they force you to pick GraphQL and how you solve the same problem using GraphQL, they seem to have whole lot of affinity towards GraphQL, CQRS pattern somehow! :D Microservices, microservices, microservices... everywhere. They want you to eat, drink, and breathe microservices and patterns around it, without critically evaluating it.
