Why do companies switch from HackerRank to CodeSignal?

Most teams know when it’s time to raise the hiring bar. Say goodbye to rewriting leaked questions, inaccurate assessments, and expensive mis-hires—and hello to predictive hiring outcomes, regulatory compliance, and deeper insights to confidently hire the right talent.

Don’t just take our word for it

If conducting interviews, CodeSignal is best in class and offers a full suite of modern, functional features to support developers and engineers of all experience levels. It allows quick editing and returns time to the interview by being dependable and efficient. I would use CodeSignal as the basis for all technical coding interviews as it allows reusability and standardizing across a big organization.

CodeSignal saves our company many hours in screening top-of-funnel candidates [and] increases our conversion rate from interviews to hires because of the candidate experience.

It feels like an actual IDE. Sometimes when I take coding assessments, I am given a minimal functionality IDE, which provides very little support. When I used Hackerrank, I felt as if I was intentionally disadvantaged to make the task more difficult. Coding assessments should be about your ability to code in an environment similar to what you would see in the workplace, and that's what CodeSignal is.

The proctored assessment that actually ensures that the candidate has done all the questions by himself, unlike HackerRank and other [platforms].

CodeSignal addresses the problem with present-day recruitment challenges. Too much of the bandwidth goes into interviewing candidates who are a complete misfit for the role. For high-volume recruitment/bulk engineer hiring needs, it serves as a perfect pre-screening tool, freeing out the time and bandwidth of Engineering talent who would have otherwise taken multiple interview rounds.

Easy to filter candidates out by ability to code, and screen those without the necessary ability to even get to the interview process. It is a much more standardized approach compared to competitors.

Frequently asked
questions

Are there free alternatives to HackerRank?

Some platforms offer limited free trials or one-time coding challenges, giving you a chance to test out the platform from inside. However, most professional-grade solutions require a subscription to unlock their full range of features.

Which platform is best for upskilling a technical team?

Several vendors provide technical upskilling solutions. iMocha is one option for companies focused on evaluating and improving their team’s technical skills. Its skill gap analysis and wide test library make it ideal for upskilling initiatives. (CodeSignal also works with many companies to pinpoint current skillsets, then develop hands-on learning paths that help engineering teams gain the skills that they need.)

How do I know which HackerRank alternative is right for my business?

Start by assessing your hiring goals, technical needs, and budget, and consider the importance of a coding assessment in your selection process. Free trials are available for many platforms, allowing you to test their features and user experience before deciding.

Can these platforms help with non-technical and soft skills assessments as well?

Yes. Some platforms can cover both technical and soft skills, helping you evaluate candidates comprehensively. If you know that you want to measure both in recruiting, invest in a comprehensive platform right off the bat.
