Interview Questions
GraphQL questions that go beyond 'what is a query'. Covers schema design, resolver patterns, the N+1 problem, caching, federation, and the security trade-offs that matter in production APIs.
API developers who work with GraphQL design flexible query interfaces that let clients request exactly the data they need. They write schemas, build resolvers, and solve performance problems like the N+1 query issue. When hiring, look for candidates who understand both the power and the pitfalls of GraphQL: overfetching prevention, query complexity limits, and caching strategies.
