About the GraphQL test

Developers can avoid over-fetching data by using GraphQL to receive exactly the data they require in a single request. They can optimize data fetching and reduce round trips to the server because of its flexible nature.

Strong typing enhances API documentation and discoverability while also assisting in the detection of problems during development. Frontend developers can use GraphQL to request the precise data they require without having to rely on backend modifications.

Because GraphQL enables subscriptions, developers can subscribe to the server's real-time updates. This is advantageous for tools like chat programs, real-time dashboards, or collaborative software that need real-time data. Developers can benefit from GraphQL's increased flexibility, performance improvement, improved teamwork, and improved developer experience.

This GraphQL test evaluates candidates’ abilities to use key GraphQL features, work with its type system and schemas, and perform validation, execution, and introspection within GraphQL.

This screening test will help you identify GraphQL developers who understand the ideas behind GraphQL and how to implement them correctly in realistic situations. Candidates who do well on this test will develop reliable, efficient GraphQL APIs.

Review from G2

VP of engineering, mid-market (51-1000 FTE)

Any tool can have functions—bells and whistles. Not every tool comes armed with staff passionate about making the user experience positive.

The TestGorilla team only offers useful insights to user challenges, they engage in conversation.

For instance, I recently asked a question about a Python test I intended to implement. Instead of receiving “oh, that test would work perfectly for your solution,” or, “at this time we’re thinking about implementing a solution that may or may not…” I received a direct and straightforward answer with additional thoughts to help shape the solution.

I hope that TestGorilla realizes the value proposition in their work is not only the platform but the type of support that’s provided.

For a bit of context—I am a diversity recruiter trying to create a platform that removes bias from the hiring process and encourages the discovery of new and unseen talent.
