Codility Reviews & Product Details

I use Codility to test my skills in design patterns, data structures, and LLD coding patterns, which helps me identify my pain points. It also assists me in creating onboarding problems relevant to the systems we work on. I like creating interviews for VS code style AI-assisted interviews using Terraform and tech stack-specific knowledge. When interviewing new hires, Codility allows us to see how they navigate the codebase in real-time and understand how comfortable they are with the tech stack and technologies we use. Also, the initial setup of Codility was quite easy, though it took some time to get the SSO link to activate my account. Overall, I think Codility is going in a good direction with their incremental development. Review collected by and hosted on G2.com.

I expected a dark mode in the website, but I can't seem to find one. It's hurting my eyes. Review collected by and hosted on G2.com.

I use Codility to test my skills on topics like design patterns, data structures, and low-level design coding patterns. It helps me discover my pain points and creates curated tests for me. Codility assists me and my team in creating onboarding problems for our project-related work based on our requirements. I like creating tests for specific interviews to assess the skill level of candidates, whether they're interviewees or existing employees. Codility is valuable as it allows me to test candidates and their approach to tasks in real-time. The AI feedback is a game changer. The initial setup was quite easy, and the instructions were pretty much self-explanatory. Review collected by and hosted on G2.com.

The quality of questions can be improved, so that it could test the candidates more effectively. Review collected by and hosted on G2.com.

What I like best about Codility is how simple and practical it makes technical hiring. Instead of just relying on resumes or theory questions, it lets candidates actually show their coding skills through real problems, which feels much fairer. The platform is easy to use, and the challenges are well-structured, so both recruiters and candidates know what to expect. I also like that it gives clear feedback and helps companies save time by automatically evaluating solutions. Overall, it makes the hiring process more transparent, efficient, and focused on real ability rather than just qualifications. Review collected by and hosted on G2.com.

One thing I dislike about Codility is that the coding tests can sometimes feel a bit stressful and rigid, especially because of strict time limits and automated evaluation. It doesn’t always reflect real-world coding, where you can take time to think, research, and refine your solution. Also, sometimes the test environment lacks flexibility, like limited debugging tools or unclear error messages, which can make it frustrating even if you understand the concept. Overall, while it’s useful, it can feel more like a pressure test than a true measure of a developer’s full potential. Review collected by and hosted on G2.com.

The platform is easy to use and well-structured. The problem statements are clear, and the coding environment is stable as well. I also like that the questions focus on real problem-solving and coding logic rather than just theory. Review collected by and hosted on G2.com.

One thing I don’t like is that I’m not convinced it works reliably for my specific tests. If something technical happens—like my PC shutting down or a network problem—the test won’t reopen at the point where I left off once it has already been completed and evaluated.

I use Codility to test myself and new onboarded engineers on specific problem sets and take mock interviews. I like the ease of use provided on Codility to create and solve problems, and to create specific problems for engineers of different levels and skills. This includes designing tests for basic design patterns and language features for entry-level and new grads, and for mid-level engineers, I focus on data structures and low-level design skills. For experienced engineers, I create tests around high-level design, performance, and latency. I also use the AI review feature on Codility to provide feedback and send it to upper management. The most exciting features are the AI review and manager dashboard, as well as the VS Code extension with AI-enabled assessment. Codility makes it easy to set up and provide tests to new developers. We switched to Codility from HackerEarth due to the ease of creating different problems and having a proper grouping for different skill sets and levels. Review collected by and hosted on G2.com.

It can improve in making curated problems for experienced engineers around low level optimisation, OS level deep knowledge problems, and Cloud platform knowledge. Review collected by and hosted on G2.com.

I use Codility for testing my skills through a well-curated set of problems and it really helps me in improving a new language or framework. I appreciate how it helps me focus on what I'm lacking and use AI to guide me in improving those areas. I especially enjoy the Terraform feature in VS Code interviews, which is very helpful for creating mock scripts to test how we call and allocate resources on cloud platforms. The initial setup was straightforward. It was easy to make a test, group it, and share it with candidates, and the tracking around keyboard, mouse, and other actions was pretty easy to set up.

It doesn't provide me with restricted cloud environments where we can test cloud skills for the candidates, and also don't have good way to test the application end to end with deployment, or CI/CD skills. Review collected by and hosted on G2.com.

It tests the various skills on different level very well based on requirement from the organization. The UI is very clean and easy to use. I contacted customer support as my test report was not getting generated, and they quickly resolved my issue and I got my test report. I've already give few of the codility tests and it works perfectly. Review collected by and hosted on G2.com.

The set of questions were very easy, the difficulty might be raised based on the requirement from the organisations. Review collected by and hosted on G2.com.

Codility helps me and my organisation assess the skill level of both candidates and employees. The platform is very easy to navigate, and the UI is genuinely impressive. It also supports multiple languages, so candidates can choose whichever language they feel most comfortable using. Review collected by and hosted on G2.com.

The difficulty level of the questions should better match the requirements and could be improved a bit, since the questions I came across were quite easy. That said, the AI feedback was very insightful. Review collected by and hosted on G2.com.

Candidates can practice some lessons provided on the website to warm up and get familiar with the platform. Companies can use this platform to get insights about their talent pool and plan for upskilling the employees. Review collected by and hosted on G2.com.

Codility can collaborate with partners to provide better content on DSA, AI, Database, etc., on their platform, which is frequently asked in interviews, so that candidates have everything in one place. Review collected by and hosted on G2.com.

Codility does a great job of filtering technical talent with real-world coding tasks that emphasize functional correctness rather than abstract puzzles. Review collected by and hosted on G2.com.

Codility’s rigid automation can end up unfairly penalizing practical engineers, because it prioritizes extreme algorithmic efficiency and obscure edge cases instead of clean, maintainable code. Review collected by and hosted on G2.com.
