It's time to rethink those take-home tests...
I've recently read a lot of opinions and posts about take-home coding tests for job applications. While these tests aim to evaluate a candidate's technical skills, they often impose significant hardships and stress. Many developers — especially those with full-time jobs, families, and other commitments — find it difficult to squeeze in the hours needed to complete them. Some of these assignments require 6–10 hours of work, which is simply not feasible for everyone. I know of several that have refused to complete them for this reason alone.
Beyond the time constraints, many of these tests don't truly assess the practical skills necessary for the job. Instead, they focus on algorithmic challenges or artificial scenarios that are rarely encountered in day-to-day software development (seriously — who uses linked lists anymore?). Worse, candidates are often expected to perform under unrealistic conditions: solving problems in isolation, without access to the tools and resources they'd normally use.
AI Is a Tool, Not a Cheat Code
A surprising number of younger developers have voiced concerns that using AI to assist with coding challenges is "cheating" or "unethical." But AI is just another tool — like an IDE, code completion, or a debugger. Developers don't write perfect code in a single attempt. Software development is an iterative process, and AI can assist in refining solutions just as much as traditional programming tools.
A critical skill today is the ability to craft effective prompts and interpret AI-generated responses. We should be evaluating a developer's ability to use AI effectively, not penalising them for leveraging modern tools.
Rethinking Developer Assessments
The real question is: what exactly are these tests evaluating? If we want to measure real-world skills, we should be focusing on:
- Problem-solving and debugging ability
- Writing clean, maintainable code
- Collaboration and communication skills
- Effective use of AI and development tools
No more LeetCode-style questions that have little relevance to daily work. No more pressure-filled live coding exercises where four people watch as a candidate struggles to perform under scrutiny.
AI Is Already Reshaping Software Development
The industry is changing rapidly. According to the 2024 Stack Overflow Developer Survey, 63% of professional developers use AI in their workflow, and AI-generated code already makes up around 41% of all code written today.
Even industry leaders like Sam Altman have stated that students should be learning AI the way previous generations learned to code. The ability to leverage AI effectively is becoming as essential as mastering an IDE or understanding software design patterns.
We need to evolve our hiring processes to reflect how software development actually works today. Instead of clinging to outdated notions of what makes a "good" developer, we should be applauding those who can leverage AI to work smarter and more efficiently. The future of development will involve AI at every stage — let's start hiring with that in mind.
