Hire deeply vetted GraphQL developers

GraphQL is an API query language that offers an efficient, robust, and adaptable solution for running queries. The data is presented to the end-user in a simplified, straightforward manner, enabling them to understand and use it.

GraphQL also makes it easier to traverse and modify the required data. It follows a client-driven architecture and uses a single, intelligent AI endpoint that allows users to specify the exact type of data they want to fetch. Hence, the results are predictable and delivered quickly. The applications developed through GraphQL are also more stable.

However, hiring GraphQL developers can be tricky. Only a few engineers have the required technical knowledge and proficiency when it comes to GraphQL. A professional with vast experience and a vetted skillset can quickly build a flexible API layer and ensure the smooth running of applications.

We aim to make the hiring process easy and efficient for you. This guide will help you identify the best talents and shortlist competent GraphQL developers, especially if you’re looking to build your team with top-notch remote GraphQL developers.

Hiring GraphQL developers without sufficient knowledge of technical recruitment and requirements might prove to be a very challenging task. To help you make a more grounded analysis, here are some of the skills proficient GraphQL developers should have under their belt.

The GraphQL developer will focus mainly on developing APIs for software programs, and as such, it is essential to have profound coding skills both on the front-end and back-end. When it comes to API development, consider hiring GraphQL developers with familiarity in back-end technologies such as Python, Java, C, C++, C#, PHP, etc., and excellent front-end skills in HTML, CSS, JavaScript, etc., as well as other related frameworks.

Hiring GraphQL developers with expertise in software development methodologies and lifecycle is highly profitable. Regardless of a developer’s area of specialization, they will need to understand the software development lifecycle. Mastering the steps and processes involved will enable better and more precise requirements analysis to avoid critical mistakes during development and assess final results.

It’s critical to use version control systems for software development. These are immensely helpful when the need arises to urgently roll back updates that seem to be malfunctioning. One of the top under-the-belt skills for a GraphQL developer is having a complete understanding of version control systems. While hiring, ensure to shortlist candidates who have demonstrable skills in Git, Mercurial, SVN, etc.

An experienced GraphQL developer is expected to know the mechanism and fundamentals of various operating systems. When working on development projects, it is normal for a developer to deal with issues related to operating systems like blocking issues, tools conflicting issues, delays, problems in communicating with other machines, and memory usage. The API created by the developer should have the capability of working on multiple machines. So, while hiring, ensure to check if the developer has a good grasp of the mechanism and functioning of the operating system(s) for which you are developing the software.

Consistently, new tools and technologies are introduced in various software development processes. Hence, it becomes crucial for GraphQL developers to keep up with industry trends and have a broad understanding of the latest, best-in-class tools and techniques that will enable the generation of new ideas and welcome new challenges to grow and scale the organization.

It is an incredibly vital skill in software development to have advanced testing and debugging skills to write code that works as expected. This is the primary reason you will need to hire talented GraphQL developers who know the fundamentals of software testing and debugging and are capable of working with well-known API tools for testing. While you may also consider hiring dedicated engineers, some checks, such as unit testing, are typically performed by developers. Understanding how to test scripts as the code is written can save a lot of time and effort in the long run.

Debugging, on the other hand, is simply identifying the bugs uncovered by testing or through other means and fixing the problem. Because testing and bugging can contribute immensely to a positive user experience, they’re valuable skills to check for in a GraphQL developer.

GraphQL is a querying language used by APIs to gather the required information from a database. GraphQL allows developers to run queries quickly and efficiently by controlling the data and displaying the relevant information on the front-end as per the requirements. Working knowledge of database technologies such as MySQL, NoSQL, MongoDB, etc., is a prerequisite for skilled GraphQL developers.

Creating a hiring funnel offers several benefits, like assisting you in selecting the top skills and identifying a GraphQL developer who will fit into your company's culture. Recruiters widely use this approach to shortlist the best applications and adequately vet suitable candidates.

Recruiters associated with the tech industry are aware of the importance of sourcing exceptional talent. To get an overview of the candidate’s practical architectural skills and gauge the level of proficiency, here are lists of possible questions to ask while conducting an interview.

Here are some more GraphQL developer interview questions that you can ask to assess a developer’s caliber.
