GraphQL Developer Assessment Template
Ready-to-run graphql developer test covering schema design & federation, resolvers & n+1 with dataloader, authorization patterns — with structured rubrics, sample questions, and AI-proof integrity baked in. GraphQL hiring tracks how teams have learned (or not learned) from the N+1 era; senior candidates default to DataLoader and persisted queries while juniors ship resolver chains that DDoS the database.
What this template measures
Every skill needed for a graphql developer hire, covered across MCQ, coding, and essay questions.

Sample questions from this template
A preview of the questions you'll see when you use this template.
Which of these is the most idiomatic way to handle schema design & federation in production?
- A.Hand-rolled implementation with no library support
- B.Battle-tested library + thin abstraction
- C.Copy from the latest blog post
- D.Avoid the pattern entirely
A graphql developer reports a regression in resolvers & n+1 with dataloader. Which signal is MOST likely to identify the root cause?
- A.Application logs at INFO level only
- B.Recent deploy diff + relevant trace
- C.Number of open tickets
- D.Restarting the affected service
Implement a small module that demonstrates authorization patterns. Include unit tests for happy path and one edge case.
Hint: Prefer clarity over cleverness; tests count.
Refactor the supplied snippet to fix a subtle bug in subscriptions & real-time without changing the public API. Explain the fix in 2–3 sentences.
Hint: Read the tests; they encode the contract.
In 200–300 words, describe how you'd evaluate a tradeoff between schema design & federation and apollo / urql / relay on a real project.
Walk us through a recent graphql project where resolvers & n+1 with dataloader was the deciding factor. (90 seconds)

Frequently asked questions
Who is this GraphQL Developer assessment template for?+
Hiring teams screening graphql developers at mid level. GraphQL hiring tracks how teams have learned (or not learned) from the N+1 era; senior candidates default to DataLoader and persisted queries while juniors ship resolver chains that DDoS the database. Use it for inbound applicants, sourced candidates, or as a take-home equivalent before live interviews.
Can I customize the GraphQL Developer template?+
Top to bottom. Add questions, remove ours, change weights, adjust difficulty mix, edit rubric language, and re-skin the candidate page with your brand. The GraphQL Developer template is software, not a fixed test.
Does this GraphQL Developer template include AI cheat detection?+
By default, every GraphQL template runs the full integrity stack: edit-pattern analysis, paste detection, keystroke biometrics. Reviewers see signal-level breakdowns alongside the score.
Can graphql developers preview sample questions before the timer starts?+
Practice mode is on by default. GraphQL Developer candidates can complete a sample task, see the rubric, and then start the real assessment when they're ready.
How do I reuse this GraphQL Developer template across multiple jobs?+
Each job clones from your team template, so the GraphQL Developer loop stays consistent across hiring managers without anyone having to rebuild it.
