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.

I think the [CodeSignal] IDE is super awesome. I’m not trying to cross Codility, but overall our engineering team thinks that CodeSignal’s is much better. That's been the biggest selling point for us.

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.

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.

I really enjoyed using CodeSignal for technical assessments during my company's hiring process. One of the things I appreciated the most was the platform's ability to provide real-time insights into candidates' problem-solving skills and code quality.
