So, it’s no wonder that an increasing number of tech recruiters are searching for more effective ways to find the best talent.
Here’s where pre-hire coding tests come in.
Such tests are a great way to assess technical talent as they give a detailed ground-truth assessment of the candidate’s skills.
Additionally, such tests can eliminate bias and even replace technical interviews, saving lots of time and costs.
But there’s a catch.
Coding tests have to be carefully graded. Otherwise, an inaccurate assessment might lead to making the wrong hiring choices.
Let’s cover all about code test grading and how it works. We’ll also explore the pros and cons of manual and automatic grading, including how to eliminate subjectivity in manual code test grading.
A coding test review refers to evaluating a pre-hire coding skills test the candidate completes as part of the job application process. Coding test reviews are a crucial step of the hiring process as they evaluate the candidate’s coding skills, ability to implement best practices, problem-solving capabilities, and technical knowledge.
Such reviews usually involve assessing the code’s structure, correctness, readability, and efficiency. This gives you a clear understanding of the candidate’s coding strengths and weaknesses and helps you make better decisions.
The way you review programming tests is crucial for the accurate and consistent assessment of all potential hires. Overall, there are two main types of code test reviews – manual and automated. Let’s take a closer look.
Automatic grading is fast, unbiased, and convenient.
The automated code review is performed with the help of automated tools that analyze the source code to identify potential errors. To ensure consistent and correct analysis, the tool uses predefined rules and best practices.
However, if the automated coding challenge review tool is not well-calibrated to show the expected average scores for junior, intermediate, and senior developers and the test scores are not well distributed, this might lead to inaccurate assessment.
This type of code review is performed by an experienced developer who evaluates the candidate’s language mastery and the code’s structure, reusability, conciseness, and readability. This allows the reviewer to provide their expert feedback on the candidate’s skills and knowledge.
While automated test review is convenient, not all technical skills tests can be automatically graded. For example, DevOps and Security challenges can be difficult to grade automatically. Additionally, candidates applying for project managers, designers, and QA will also need to be graded manually.
So, manual grading is inevitable in some scenarios.
However, if not done in a constructive manner, manual grading can lead to subjectivity, decreasing the grading accuracy.
Subjectivity is almost always present in the following scenarios:
Codeaid is a coding test website that offers various real-world simulation coding tests and both automatic and manual grading features.
This gives you the freedom to decide which coding challenge review approach to adopt.
Furthermore, Codeaid’s automatic grading feature does not only do the hard job for you, but it also gives you a highly granular report on how the grade was compiled. This allows you to see all key insights and details on which sections the candidates passed and which they failed.
On the other hand, the manual grading feature offers an even more refined evaluation. This comprehensive approach is based on a predefined framework of various criteria, reducing subjectivity and ensuring a fair assessment. This coding assessment method is ideal for coding tests where automated grading is not possible (for example, for architecture positions).
You can finally ditch the superficial coding tests for interviews and try a refined and accurate coding test tool that will help you find top talent.
Overall, both manual and automatic coding tests have their pros and cons. Which grading approach you choose depends on a few factors, including what position you’re hiring for.
Whether you choose manual or automatic code review, you should ensure the tool you’re using offers best of both. Automatic grading can give you quick and easy access to key insights into the candidate’s performance and abilities. On the other hand, manual grading provides a well-controlled assignment process, grading process, and reviewer evaluation process so subjectivity is minimized as much as possible.
