We rely heavily on the live coding functionality, along with the overall user experience and interface. Negative feedbacks we usually recieve are more connected to the type of exercise we implement than the tool itself. We’ve been using this tool at QuintoAndar for several years and have not encountered significant issues or negative feedback from candidates or interviewers. Furthermore, Marie Louise has consistently provided supportive and timely assistance. Review collected by and hosted on G2.com.

Prices were slightly elevated when we had to increase the number of tests due to the internship program. It would be helpful to have more flexibility in the annual plan to account for seasonal peaks. Review collected by and hosted on G2.com.

I appreciate Codility for its user-friendly interface, which makes the interviewing process seamless and efficient. The coding editor closely resembles what we use in Visual Studio, providing a familiar environment which enhances the coding experience during interviews. Additionally, the ability to interact effectively with interviewees is quite impressive. I also value the comprehensive repository of problems that allows me to easily access and choose from a variety of coding challenges. Sharing problem statements across the organization is another significant feature that promotes consistency and collaboration team-wide. The test case compilation and results are very satisfactory, maintaining a high standard in evaluating candidates' technical skills. Review collected by and hosted on G2.com.

I experience challenges with Codility when it comes to SQL-related tasks, specifically due to the lack of precomputed tables. This makes it difficult for interviewees to execute queries directly, as they have to initialize the context of the problem without an existing table. This limitation complicates the evaluation process, particularly for problems that require a pre-existing table to be in place for the candidate to write and execute queries efficiently. It's a bit of a bummer, especially for initializing the context necessary for certain SQL evaluations. Review collected by and hosted on G2.com.

I love how Codility allows me to confidently and objectively assess candidate technical abilities through the ability to run code, which provides objectively correct information on the applicant's accuracy. The immediate syntax highlighting and the capability to run code samples on a VM to validate expectations are invaluable features. Running code and unit tests gives objective feedback, enhancing interviewer confidence and providing immediate, relevant feedback to candidates, tailored to their code. I appreciate that Codility allows me to include minimal unit tests to precisely pinpoint incomplete or inaccurate functionality, with compilation errors offering exact line numbers and syntax issues, thereby offering insights into a candidate's debugging approach, which feels akin to real on-the-job situations. Recently, the platform has integrated a VS Code editor, which shows promising potential to expand the development environment capabilities significantly, making it closer to the company's environments.

I found the recent integration of the VS Code editor in Codility to be promising but currently challenging to use. The configuration process is not straightforward, and my team and I struggled to figure out how to set it up properly, particularly to expose and run commands like Run & Debug without the usual configuration files like .vscode/launch.. This adds pressure as we need everything prepared before interviews with no confidence that it will run smoothly under time constraints, posing a risk to the candidate experience. Additionally, accessing the Terminal for installing dependencies, which would enhance the interview environment, was not intuitive. Review collected by and hosted on G2.com.

I really appreciate Codility's environment, which stands out as a valuable tool. The platform offers real-world coding questions that align closely with the day-to-day activities of candidates. This feature helps us effectively assess the skills of developer applicants, ensuring that our team can efficiently filter through a significant number of candidates. Moreover, Codility's user interface is notably easy to use, making the process of creating assessments straightforward. Additionally, the support from Codility's team has been good, especially during the setup phase, as they provided excellent assistance when integrating with their API. Their environment, accompanied by the robust question sets catering to our specific technology stacks, greatly enhances the overall experience of using Codility within our hiring process. Review collected by and hosted on G2.com.

I find that while Codility claims to support multiple stacks, there are inconsistencies in the question bank. For some stacks, there is a large volume of questions, but for others, it's limited, making it challenging to create proper assessments, particularly for hiring senior developers. The disparity results in only easy questions being available for certain stacks, which is inadequate for evaluating high-level positions. Ideally, I would like to have a mix of question difficulties—easy, medium, and hard—related to real-world scenarios to properly assess candidates' capabilities. This content gap is a significant drawback for us. Review collected by and hosted on G2.com.

I have been using Codility primarily for interviewing candidates, and over the past three years, it has been an integral tool in my company's hiring process. I am happy with Codility and find the setup to be really simple, providing a smooth onboarding experience. One feature that stands out to me is the integrated development environment (IDE) on Codility, which I use extensively during interviews. Additionally, the integration with my reports is really useful, particularly for handling architecture-related questions, making Codility indispensable for efficiently conducting and managing technical interviews.

I find the video part of Codility, including chats and video calls, occasionally struggles, particularly with certain browsers or on certain days. The sound could also be problematic at times. These issues can affect the smooth execution of interviews, and I would definitely invest in improving these aspects. Review collected by and hosted on G2.com.

I used Codility for both as interviewer and interviewee. I like the part about that interviewer/interviewee can interact to each other real time through chats. Also, UI is neat and clean. Review collected by and hosted on G2.com.

Codility is a great platform, but I wish the user interface for the coding section were more intuitive and less rigid. I understand that compiling code is a fundamental part of the interview process, but sometimes it can be difficult just to get the code to compile, which ends up wasting time. Often, the interviewer simply wants to move on to testing the code, but the strictness of the interface can make that challenging. Review collected by and hosted on G2.com.

UI is simple and straightforward for candidate to login and access the platform. I have been using this platform atleast once a week. Haven't required to reach support so far, has been a smooth experience. Review collected by and hosted on G2.com.

I wish there can be 1+ tasks with plain text editors for more flexibility. Because in some interviews for multiple tasks we prefer no syntax help, that is a restriction currently. Review collected by and hosted on G2.com.

It's easy to use, and it also automatically detects any suspicious activities. Review collected by and hosted on G2.com.

I think, proctoring is not possible in codility, meaning we should be able to live proctor the assessment, that would be handy for me. Review collected by and hosted on G2.com.

What stood out to me from the start was how Codility lets you focus on what really matters—understanding how a candidate thinks, solves problems, and writes code under time pressure. It’s not just about getting the right answer. You get a real sense of someone’s logic, coding style, and approach to debugging.

I’ve been using Codility as part of the hiring team at Zalando, where I work as a Senior Software Engineer in Berlin. We’ve used it to assess candidates for different roles, especially in the early screening stages. And honestly, the platform has made that process a lot smoother.

The timeline feature is one of my favorites. It shows how the candidate progressed through a task—from when they started, to when they copy-pasted code, or paused—helping us understand their thought process better. It’s been a great way to tell whether someone rushed, took time to plan, or struggled at a certain step.

Another big plus: the detailed playback view. You can actually replay how a candidate solved the task, with the question and code side by side. This keeps the evaluator in the right context and helps us evaluate not just what the candidate wrote, but how they arrived at the solution.

The platform also flags suspicious activity, like tab-switching or copy-pasting, which adds another layer of insight during evaluations. And the dashboard shows per-task scores, time taken, and complexity indicators. All of this helps us go beyond just a score and look at the full picture.

Codility does a solid job for backend and general coding assessments. The test variety includes real-world engineering challenges, and live sessions have worked well for remote interviews—we’ve had good experiences collaborating with candidates live and observing how they think out loud. Review collected by and hosted on G2.com.

The UI can feel quite cluttered. There’s a lot of information packed into the dashboard, but not all of it feels necessary—or easy to navigate. Sometimes it’s hard to focus on what really matters.

Also, as a frontend-heavy team, we’ve often felt that Codility leans too much towards backend-style assessments. There’s limited support for evaluating real-world frontend skills—things like async logic, UI reasoning, or performance trade-offs. We've had to build and use custom tasks outside the platform just to evaluate frontend engineers more effectively.

While Codility does surface things like time complexity for solutions, a human review is still necessary to judge the actual quality of the code—especially for senior roles. Review collected by and hosted on G2.com.

One thing I really liked about the recent updates in Codility is how much smoother and more intuitive the interface has become—it feels cleaner and easier to navigate, especially under time constraints. The questions also seem more practical now, focusing on real-world scenarios rather than just theoretical algorithms, which makes the experience more relevant. I also appreciated how the platform handles different programming languages better, especially with modern C++ features that used to cause issues earlier. The test reports are now more informative too, making it easier to understand where you went wrong—whether it was performance, logic, or edge cases. Plus, being able to review practice problems on mobile is a small but handy touch. Review collected by and hosted on G2.com.

Yes, there are a few areas where Codility can still improve. Sometimes the execution environment feels a bit slow, especially when running multiple test cases or handling larger inputs—it adds unnecessary pressure during timed assessments. Also, while the real-time feedback is useful, it would be great if it included a bit more context, especially when something fails unexpectedly (like segmentation faults or timeouts). Another improvement could be in the code editor itself—basic features like auto-complete, function hinting, or even dark mode would make coding more comfortable. Lastly, the question difficulty can vary a lot, even within the same test, so a more balanced progression in complexity would make the overall experience fairer.
