GraphQL interviews probe schema design, the N+1 problem and dataloader patterns, federation across teams, and security pitfalls like query depth and complexity limits. Practice questions hiring teams ask for API-platform and frontend-platform roles.
Sample questions
These are the kinds of questions you'll drill. Real mock rounds will generate many more — tailored to the exact JD you paste in.
How would you design a GraphQL schema for an e-commerce product catalogue with 50 teams contributing types?
Explain the N+1 problem in GraphQL and how dataloaders solve it.
Compare GraphQL Federation vs Schema Stitching — when would you pick each?
How do you prevent malicious clients from bringing down your GraphQL server with deeply nested queries?
When is REST a better fit than GraphQL? Defend your answer with concrete trade-offs.
Reading GraphQL questions isn't the same as answering them live. You need the rep — the pause, the clarifying question, the moment where you realize you forgot the framework. We put you in that exact spot, then show you what a strong answer would have looked like.
