Software Developers Technical Assessments: Types
1. Coding Challenges and Assignments
Useful for: Evaluating a developer's coding abilities
How to administer them: Through online platforms, the developer is given a task that tests their coding skills. They might be asked to build a particular feature or solve a coding challenge.
The developer is evaluated based on the quality of the code, problem-solving ability, and ability to write efficient and effective code.
2. Technical Skills Assessments
Useful for: Evaluating a developer's technical abilities in a more comprehensive way
How to administer them: Via coding challenges and assignments as well as assessments such as multiple-choice quizzes, open-ended questions, and practical exercises
Technical skills assessments test a developer's understanding of programming concepts and principles, as well as their familiarity with specific programming languages, frameworks, or tools.

Best Practices for Developing Technical Assessments
1. Define the job requirements and skills needed
The first step involves identifying the core competencies, technical knowledge, and skills essential for success in the role.
Obtain this data by conducting job analysis and consultation with subject matter experts (SMEs). Once the key competencies and skills are identified, clearly state them in the assessment to ensure that the candidate's technical abilities align with the job requirements.
2. Create realistic scenarios and projects
A software developer technical assessment should be designed to simulate real-world scenarios and projects that candidates will likely encounter on the job. This ensures the assessment accurately measures the candidate's technical skills and problem-solving abilities.
Pro tip: Realistic scenarios and projects can be developed by SMEs with experience working in the role or by consulting current employees in similar positions.
3. Avoid bias in assessment design and scoring
Bias can creep into technical assessments in many ways, such as through the wording of questions, the selection of topics, and how responses are scored.
To avoid bias, review assessment content and scoring criteria with an objective eye. Additionally, assessments should be piloted with a diverse group of candidates to ensure they are fair and unbiased.
4. Provide clear instructions and expectations
Candidates should be provided with clear instructions on:
- How to access and complete the assessment
- Expectations regarding the time frame for completion
- Scoring criteria
- Consequences of not completing the assessment
Providing candidates with clear expectations can help reduce stress and anxiety, allowing them to focus on their performance.
5. Use automated assessment tools to streamline the process
If you want to reduce the time required to grade assessments, use an automated tool such as coding environments, plagiarism detectors, and machine learning algorithms.
However, it is essential to ensure that these tools:
- Are reliable and accurate
- Do not introduce bias or errors into the assessment process
- Are used in conjunction with human reviews to ensure that the assessment accurately reflects the candidate's technical skills
Best Practices for Administering Technical Assessments
1. Communicate with candidates about the assessment process
It is important to be transparent with candidates about the assessment process. Communicate what the assessment entails, how it will be evaluated, and how the results will be used.
Let candidates know what tools or software they may need to complete the assessment and provide any relevant resources or materials that they may require.
2. Give candidates sufficient time to complete the assessment
Technical assessments can be time-consuming, so giving candidates enough time to complete them without feeling rushed is important. Be sure to communicate the time limit or deadline for completion, and if possible, offer some flexibility if a candidate needs extra time.
3. Provide feedback and follow up with candidates
Once the assessment is complete, provide timely and constructive feedback to the candidate. This will help them understand:
- How they performed
- What they did well
- Where can they improve
Pro tip: Follow up with candidates who did not pass the assessment to provide feedback on how they can improve and potentially reapply.
4. Ensure fairness and consistency in the assessment process
It is important to ensure that all candidates are given the same assessment and are evaluated in a consistent and fair manner:
- Use objective criteria and scoring rubrics to assess candidates and avoid subjective biases
- Ensure that the assessment aligns with the skills and experience required for the job
5. Protect candidate privacy and data security
Assessments may include personal information and confidential data, so protecting candidate privacy and data security is important. Follow these tips:
- Use secure assessment platforms and follow best practices for data storage and handling
- Be transparent with candidates about how their data will be used and who will have access to it
