When and Why You Should Conduct Coding Tests for Developers


Hiring a developer to join your team can be a difficult process. In addition to the standard screening process, you must also evaluate the technical skills of prospective developers. One of the best ways to gauge a developer’s knowledge is by conducting coding tests. But when should you use coding tests? Read on to learn more about coding tests, when and why you should use them, and some alternative methods for hiring developers.

What Are Coding Tests?

Coding tests are designed to evaluate a potential employee’s knowledge of programming languages, application development frameworks, software engineering principles, algorithms, data structures, databases, and more. They are usually conducted in a supervised environment with the help of experienced professionals who can assess the applicant's ability to solve complex problems using their coding skills. The results of these tests can provide invaluable insight into the potential employee's ability to handle complex tasks in the future.

When Should I Use Coding Tests?

Coding tests should be used whenever you have an open position that requires programming or software engineering experience. For example, if you are looking for an experienced software engineer or a senior front-end developer with extensive knowledge of HTML5 and JavaScript libraries like React or AngularJS, then it makes sense to conduct a coding test as part of your selection process. This will give you an indication of how well-versed the applicant is in those technologies before inviting them for further interviews or assessments.

The Benefits of Coding Tests

  1. Assess Technical Skills: Coding tests provide a practical way to assess a candidate's technical skills. They can demonstrate a developer's ability to write clean and efficient code, use appropriate programming paradigms, and apply software engineering best practices.
  2. Evaluate Problem-Solving Skills: Coding tests present candidates with real-world coding challenges that require problem-solving skills. They can showcase how a developer thinks through complex problems, breaks them down into smaller tasks, and implements effective solutions.
  3. Identify Knowledge Gaps: Coding tests help identify any gaps in a candidate's knowledge or experience. They can reveal areas where additional training or support may be necessary to ensure the developer can meet the requirements of the role.
  4. Save Time and Resources: By conducting coding tests early in the hiring process, you can filter out candidates who do not meet the technical requirements, saving time and resources on further assessments or interviews.

Alternative Methods for Hiring Developers

While coding tests can provide valuable insights into an individual's abilities as a programmer or software engineer, there are other ways to assess whether someone would be suitable for your organization's needs.

  1. Questions About Past Experiences and Projects: Asking targeted questions about a candidate's past experiences and projects can help assess their practical knowledge and problem-solving abilities. Inquire about specific challenges they faced, the technologies they used, and the outcomes they achieved.
  2. Hypothetical Scenarios: Presenting hypothetical scenarios based on real business challenges can gauge a candidate's ability to think critically and come up with creative solutions. This can provide insights into their problem-solving skills and how well they would fit into your organization.
  3. Sample Projects: Providing applicants with sample projects that simulate real work assignments can give you a glimpse into their coding abilities and how they approach tasks. This allows you to evaluate their coding style, adherence to best practices, and ability to deliver quality work.


Finding talented developers who fit seamlessly into your existing team is no easy task. Conducting coding tests can be a valuable tool in assessing a candidate's technical skills, problem-solving abilities, and suitability for the role. However, it's important to consider other methods as well, such as asking about past experiences, presenting hypothetical scenarios, and providing sample projects. By using a combination of these methods, you can make a well-informed decision and ensure that only the most qualified individuals secure positions within your organization.
