Full-Stack Developer Test

A full-stack developer test can help you assess whether a candidate has the skills and knowledge required for building software for both front-end and back-end.

  • What is a full-stack developer test?

    A full-stack developer builds website applications, as well as maintaining and troubleshooting existing websites and web pages.

    A full-stack developer test allows recruiters to evaluate candidates on a range of subject knowledge related to the development of software using both front-end and back-end skills (collectively known as full-stack).

    Questions a full stack developer test might contain include topics such as:

    • Knowledge of design and development processes
    • Testing and debugging
    • Best practices for writing code
    • UI and UX design
    • Creating servers and databases
    • Cross-platform compatibility and optimization
    • Software testing
    • Developing APIs and RESTful services
    • Security considerations and scalability
    • Communicating with key stakeholders and decision-makers

    The test provides insight into the core skills of a full stack developer and automatically compares this data with other candidates, allowing you to make bias-free shortlisting decisions.

About the Full-Stack Developer Test

A full-stack developer test provides critical assessments of an individual's knowledge for both front-end and back-end programming required to build software applications. As such, the test can help recruiters make better hiring decisions.

Skills like front-end and back-end knowledge, problem-solving, programming language skills and technical knowledge are critical to assess how a full-stack developer will perform.

  • Why should you use a full-stack developer test for recruiting?

    Although resumes, portfolios and projects can be a useful demonstration of skill, it's difficult to tell how much contribution an individual full-stack developer had, as they usually work in teams. This is why a skill test can be critical during the pre-screening stages of the recruitment process.

    The full-stack developer test assesses a range of skills and competencies including a personality assessment for cultural fit, technical programming skills, communication (particularly translating problems into non-technical layman's terms) and problem-solving. It is presented in the form of multiple-choice questions.

    Job roles you might find the full-stack developer test relevant for include:

How our test assesses full-stack development skills

Candidates will need to answer a range of questions that measure industry-specific technical skills where applicable (e.g. CSS), soft skills (e.g. teamwork), aptitude (e.g. logical reasoning) and relevant personality dimensions (e.g. patience). The results present a holistic view of how well suited each candidate is for the job at hand, using a data-driven approach.

The format varies by type of question, including multiple-choice for aptitude and technical skills, situational judgement for soft skills and agreement on a Likert scale for the personality dimensions. This approach ensures candidates are being assessed in an accurate and fair manner, and that results reflect the true underlying qualities of each candidate.

The characteristics, abilities and knowledge necessary to be a full-stack developer were identified using the US Department of Labor's comprehensive O*NET database. O*NET is the leading source of occupational information that is constantly updated by collecting data from employees in specific job roles.

During the development process, test questions were rigorously analysed to maximise reliability and validity in line with industry best practices. They were created by our team of I/O psychologists and psychometricians – who collaborated with subject-matter-experts – and field-tested with a representative sample of job applicants who have varying experience, just like you might find in a talent pool.

Each test is reviewed by a panel of individuals representing diverse backgrounds to check for any sensitivity, fairness, face validity and accessibility issues. This ensures each candidate has a fair chance of demonstrating their true level of expertise.

Our full-stack developer test is monitored to ensure it is up-to-date and optimised for performance.
