Coding assessments is a term that often makes developers sigh in exasperation. It's not just about having to prove one's coding chops, which developers might feel uncalled for; it's the dread of wading through hours of potentially irrelevant tasks, which are usually unpaid. Developers also frequently comment on how coding assessments are so out of touch with current tech trends and with roles that they have to practice specifically for them, even if what they’re asked to complete doesn’t match the role they’re applying for.

Devs care for companies that respect their time and craft and will not want to get themselves into just another generic test. But when executed right, specific tools can help pivot this gruelling process into a meaningful evaluation.

Besides their lousy rep, coding assessments do have some pitfalls. As some tools, such as HackerRank, become more popular, more candidates try to crack it and cheat, making any attempt futile. Moreover, most of these tools only gauge technical skills and not a cultural fit. That’s why HR teams should also count on platforms that pre-vet candidates, allowing the focus to shift from tech skills to compatibility.

Considering these circumstances, these are the best coding assessment tools to help recruiters hire top tech talent in 2023 (without eliciting rage or eye-rolling):

2. CodeSignal

This assessment platform supports 70+ languages, frameworks, and tools.

Something is fundamentally wrong with the mindset of this industry if after almost a decade working, you have to practice for weeks or months to perform tasks you won't need to do in your next role. — Reddit user TheChanger

3. HackerEarth 

Initially, HackerEarth was developed as a venue for business hackathons. Since then, functions for pair programming interviews and code screening have been introduced.

7. CodinGame

At the beginning of the recruiting process, CodinGame might help to contest one of the hardest, coldest truths about coding assessments: that they’re dreadful, bland, and innocuous. CodinGame, for its part, is outstandingly far from that status.
