Hi Ashish, thank you for taking the time to share your feedback. We sincerely apologize that you had a negative experience during your Codility test due to a technical incident and understand how frustrating it must have been. If you haven't already, we encourage you to reach out to the company or organization that invited you to take the assessment, as they can provide an opportunity to retake your assessment and demonstrate your skills.

"A good tool with a poor editor"

1.5/5

What do you like best about Codility?

The intelligence behind the tool is amazing, good excersise selection, good topics, alternatives Review collected by and hosted on G2.com.

What do you dislike about Codility?

Most of it, the code editor, there isn't a developer working in 2025 (or even pre 2000) who isn't used intellisense, even teammates working with big companies don't remember the exact name of classes... because we can type the work with either just a single keypress or a shortcut (ironically JRs have an easier time using the tool since they don't have 8+ years of experience with automation) Review collected by and hosted on G2.com.

Hi Carlos, we appreciate you taking the time to review Codility, and thank you for being a customer. We're sorry to hear that your experience with the code editor was unsatisfactory. If you haven't tried our new VSCode IDE, it supports Intellisense and we highly recommend trying it out for a more true-to-life coding experience. If you're willing, we'd love to hear more about your experience – send us an email at hire-team@codility.com!

"Codility’s Strengths and Areas for Improvement"

4.5/5

What do you like best about Codility?

I recently attempted Codility. Honestly, I would say it was some mix of both challenge and insight. The platform is quite well designed with a smooth interface to coding, clear problem statements, and real-time feedback about performance. Review collected by and hosted on G2.com.

What do you dislike about Codility?

Probably, one of the issues with Codility is that the tests can sometimes appear a little too edged on the edge cases. I think it might be frustrating for developers more accustomed to solving practical, everyday problems. In some cases, very severe time limitations and scoring systems really add unnecessary stress on candidates. Instead of exploring creative solutions, candidates focus more on trying to get a qualifying score. Review collected by and hosted on G2.com.

What problems is Codility solving and how is that benefiting you?

Codility helps bridge the challenge of assessing coding skills on objective and efficient grounds. For me, it's like a mentor, which initiates you to first of all think as a software engineer would, maximize your codes, and be considerate of the edge cases in real-world conditions. Providing problems that are similar to those you might encounter in a job interview or while trying to solve especially complex coding problems on the job makes the process of preparing for technical interviews much easier.
