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.

Sample questions from this template

A preview of the questions you'll see when you use this template.

Multiple ChoiceEasyQuestion 1

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
Multiple ChoiceMediumQuestion 2

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
CodingMediumQuestion 3

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.

CodingHardQuestion 4

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.

EssayMediumQuestion 5

In 200–300 words, describe how you'd evaluate a tradeoff between schema design & federation and apollo / urql / relay on a real project.

VideoEasyQuestion 6

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.
