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.

This test is created by a subject-matter expert

Maria V.

María is a developer and security engineer specialized in auditing backend code that consume massive amounts of data. She has won dozens of bug bounties from testing large code bases like Apollo Server and React Native.

Her experience analyzing APIs for bad practices have given her an intricate knowledge of what makes a clean code base, and how to identify qualified developers.

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.

FAQs

An assessment is the total package of tests and custom questions that you put together to evaluate your candidates. Each individual test within an assessment is designed to test something specific, such as a job skill or language. An assessment can consist of up to 5 tests and 20 custom questions. You can have candidates respond to your custom questions in several ways, such as with a personalized video.

A video question is a specific type of custom question you can add to your assessment. Video questions let you create a question and have your candidates use their webcam to record a video response. This is an excellent way to see how a candidate would conduct themselves in a live interview, and is especially useful for sales and hospitality roles. Some good examples of things to ask for video questions would be "Why do you want to work for our company?" or "Try to sell me an item you have on your desk right now."

Besides video questions, you can also add the following types of custom questions: multiple-choice, coding, file upload, and essay. Multiple-choice lets your candidates choose from a list of answers that you provide, coding lets you create a coding problem for them to solve, file upload allows your candidates to upload a file that you request (such as a resume or portfolio), and essay allows an open-ended text response to your question. You can learn more about different custom question types here.
