Mercer | Mettl I/O: Best Role-Based Assessment Platform to Find & Develop Good Coders

There is no single way of measuring the skills of a programmer. A good programmer doesn't only mean having good coding skills. There are other aspects too that make a coder adept at dealing with programming challenges.

Coding is a domain where new technologies and ideas surface continually. Good coders should grasp new things and hone their skills continuously. It is cumbersome to conduct a coder’s programming skill assessment as it involves different roles that analyze their specific abilities.

In this context, a role-based coding assessment platform works best in evaluating a coder’s skills. It provides a coding environment with real-life projects to assess the broader coding skills for specific roles. It offers tools and processes needed to develop software. A coder is given an interface to undertake a simulation exercise and perform a task within a specified time.

A programmer can be easily evaluated on specific skills using a role-based coding assessment platform, but it doesn't measure a coder’s laziness and impatience, as suggested by Larry Wall. However, the comprehensiveness of the analytical results assures concrete results. Let’s understand why a role-based coding assessment platform enables careful analysis of software development abilities.

It’s about making individuals undergo various tests and processes to evaluate their coding skills. These assessments are done using a real-life, hands-on project in a coding environment that provides a comprehensive overview of a coder’s skills and prowess. Such coding environments offer detailed reports and analysis of a coder’s thinking process.

The assessment of coding skills involves applying concepts and the thinking process of an individual while writing a code based on a given challenge. Several challenges emerge while assessing coders.

They are as follows:

The purpose of the role-based coding assessment is to use a comprehensive means of giving coders a research-based methodology to apply their coding and problem-solving abilities.

Mercer | Mettl I/O is a well-crafted tool. But let us first understand the software development roles for which it has been designed. In the domain of software development, various roles decide the entire coding and development process. Mercer| Mettl I/O has been designed as an assessment platform covering every function under coding.

The Mercer | Mettl I/O is a role-based coding assessment platform that provides a combination of multiple integrated development environments and tools.

Data Scientist

DevOps Engineer

Quality Assurance Engineer

Coding is a vast domain and assessing someone for their particular skills is a time-consuming affair. Creating a coding environment helps in such specific purposes where you have to zero in on an individual or help your employees learn and upskill in a particular software development area.

It helps in making the cognitive knowledge easily comprehensible and real for the users. Working on this coding interface makes it much easier to train a candidate for the relevant skills. Mercer | Mettl’s I/O coding assessment platform is easy to use and can be easily customized for various assignments, respective to different software development roles.

As the above image suggests, hiring and skilling programs involve 4 steps that encompass important ideas related to software programming.

• Configure the coding environment- It’s about giving the software developer the complete interface to develop a program. Depending on different software roles, the user is provided with the essential software, packages, libraries and tools.


• Create real-world challenges- Create a challenge and frame a problem related to a specific domain of software development. Ensure to give the candidate the right set of questions for a comprehensive assessment. Customize these real-world, hands-on problems as learning and development needs.


• Auto-graded reports- There is no need for human intervention to undertake the final evaluation of the candidates. The assessment is auto-graded and involves all the necessary analytics and coding steps undertaken by the candidate. During learning and development, these auto-graded reports assess the upskilling process fairly.


• Holistic assessment- You get the best possible results in making a holistic assessment of the candidates’ coding skills. The Mercer | Mettl I/O has been designed to provide comprehensive results considering every detail and step in the software development process.

A role-based coding assessment platform works efficiently for learning and development. For example, in your organization, some people may wish to upskill or learn and understand the advancements in the software development domain. Make a comprehensive assessment of the candidates and analyze the essential technical competencies needed to be acquired by the employees for enhanced efficiency.

Consider a scenario where a candidate applies for a developer’s role and you, as a business owner, want to be sure about the candidate’s skills. You can frame a set of questions related to the job profile and let the candidate work on it. The candidate may answer those questions well. However, such evaluations don’t depict a clear picture, as applying the same knowledge can be different for different individuals. The practical aspect of knowledge lends more transparency.
