Why Companies Should Remove Live Coding Exams in Their Hiring Process

As someone deeply entrenched in the tech industry, I've seen firsthand how traditional coding exams in the hiring process often fail to capture a developer's true potential and fit for a role. These exams, frequently filled with abstract problems like Fibonacci sequences or deeply nested object manipulation, may not accurately reflect the daily tasks or challenges a developer will face on the job.

In my experience, the daily routine of a developer involves more than just solving algorithmic puzzles. It's about collaborating with team members, understanding project requirements, debugging real-world issues, and leveraging a variety of tools to find the best solutions. The ability to effectively use resources like Google and ChatGPT to troubleshoot and optimize code is far more indicative of a developer's practical skill set. The rigid nature of coding exams fails to consider these critical aspects, instead focusing on isolated problems that rarely occur outside the context of the test.

Moreover, job experience speaks volumes. A developer with a proven track record in real-world applications has demonstrated the ability to navigate the complexities of actual projects. They know how to manage time, prioritize tasks, and integrate feedback—all essential skills that a coding exam can't measure. The ability to utilize all available tools efficiently, rather than just memorizing algorithms, is what truly drives productivity and innovation in a professional setting.

The advent of generative AI like ChatGPT has further rendered traditional coding exams obsolete. Developers can now generate and refine code quickly, simplifying complex problems into manageable tasks. This technology underscores the need for a shift in hiring practices. Instead of pressuring applicants with live coding exams that induce stress and may not reveal their true capabilities, companies should consider providing them with a project. Allowing candidates to use all the tools at their disposal, including AI, mirrors the real work environment more closely.

For instance, giving an applicant a small-scale project that mimics actual job tasks can be far more telling. Let them use their preferred resources, then have them present and explain their approach and solutions. This method not only assesses their technical skills but also their problem-solving process, creativity, and ability to articulate their work.

In conclusion, the traditional coding exam is an outdated measure of a developer's potential. Real-world experience, the skill to effectively use modern tools, and the ability to manage and present projects should take precedence in the hiring process. This approach not only aligns better with the actual job requirements but also respects and leverages the capabilities of today’s developers in a meaningful way.
