"Live Coding and Intuitive Interface Elevate the Experience"
What do you like best about Codility?

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.

What do you dislike about Codility?

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.

"Intuitive Platform for Coding Tests with Real-Time Challenges"
What do you like best about Codility?

I used Codility for coding tests, and it's a super platform. I appreciate its automatic evaluation and anti-cheating environment. I like the real-time coding challenge debugging and the evaluation of refactoring skills rather than just algorithms, which help identify the gaps through real enterprise questions. I found the initial setup really intuitive. Review collected by and hosted on G2.com.

What do you dislike about Codility?

There are some IntelliSense features to be added like local IDEs have, such as autocorrect, autocomplete, and method parameter suggestions. Review collected by and hosted on G2.com.

Response from Christopher Greco of Codility

Hi Vikash, thank you for the kind review and the 10/10. Great to hear the platform felt smooth and the anti-cheating environment gave you confidence in the results.

On the IntelliSense point, I wanted to share a bit of context. Codility assessments come in a few task types, and the IDE experience varies by type. Fundamental tasks, which are our shortest skill-check format, run in a lightweight editor by design, so autocomplete and parameter hints are limited there. Real-life tasks and our Interview product run in either a fully-featured IDE or, currently in preview, a full VS Code environment with sidecar services, terminal access, and the IDE features you would expect, including autocomplete and method signature suggestions. None of this is gated, it just depends on which task type the hiring team chose for the assessment.

Your feedback on bringing richer editor support into the fundamental task experience is useful and I passed it to the product team.

If you have any questions, feel free to reach out at g2@codility.com.

"Flexible Difficulty and Curated Coding Assessments for Onboarding"
What do you like best about Codility?

I like setting different difficulty problem for one or many programming languages, and making curated tests for team or to create an assessment to onboard new engineers. Review collected by and hosted on G2.com.

What do you dislike about Codility?

It doesn't have debugger and intellisense inbuilt which makes it hard to test engineers in those skills or lack of AI engineering problems. Review collected by and hosted on G2.com.

"Codility: Indispensable Tool for Effective Selection Processes"
What do you like best about Codility?

I think Codility is a very usable product. It is very well designed at the interface level because it is simple for both the candidate and the interviewer, and it always works well. I have never had errors using Codility in an interview, which is quite critical for a selection process to be smooth and error-free. It helps me evaluate candidates with different technical profiles since the platform supports various languages. Additionally, the real-time support is excellent as we can see what the candidate is doing in real-time and then review the report and feedback, which helps us a lot in the selection process.

"Effective Interview Tool, Needs Better SQL Support"
What do you like best about Codility?

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.

What do you dislike about Codility?

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.

"Smooth, Hiccup-Free Testing Experience"
What do you like best about Codility?

The test environment was smooth. I didn’t encounter a single hiccup throughout the test. Review collected by and hosted on G2.com.

What do you dislike about Codility?

It didn’t have camera proctoring, which makes the test more prone to cheating. Review collected by and hosted on G2.com.

Response from Christopher Greco of Codility

Hi Bibek, thank you for sharing your experience. I'm glad to hear the test environment ran smoothly for you!

On the proctoring point, I wanted to clarify that Codility does offer camera proctoring as part of our Integrity controls, alongside ID verification, behavioral monitoring, and risk scoring. It's turned off by default so hiring teams can choose the right level of oversight for each assessment, and it can be enabled at no additional cost whenever a customer decides they need it.

We've also been investing heavily in integrity signals beyond the camera. In November 2025 we launched Live Proctoring Signals, which gives reviewers real-time notifications when a candidate switches browser tabs, loses focus, copies the task description, or pastes code from an external source. Every event also lands in a live integrity timeline for review.

On the AI side, hiring teams can enable or disable our AI Assistant per assessment, and every candidate interaction with it is captured as reviewable AI activity. That gives reviewers a clear record of how AI was used during the test, which is increasingly what matters when the work itself is AI-enabled.

The candidate experience stays smooth and uninterrupted, while hiring teams get the visibility they need to make confident, informed decisions.

If you have any questions or want to see any of this in action, you can reach out directly to me at g2@codility.com.

"Seamless and User-Friendly Coding Assessment Platform"
What do you like best about Codility?

My experience with Codility has remained consistent because the platform continues to provide a smooth and reliable environment for coding assessments. The interface is intuitive, and the questions are well-structured and clear, making the overall experience efficient and stress-free.I appreciate how straightforward and distraction-free the platform is. The problem statements are concise, and the coding interface works smoothly without any lag. It allows me to focus entirely on problem-solving without worrying about technical issues. Review collected by and hosted on G2.com.

What do you dislike about Codility?

It would be helpful if users could review previously submitted tasks and see detailed feedback or test case results after submission. This would improve learning and help candidates understand where they went wrong. Review collected by and hosted on G2.com.

"Boosting Candidate Assessment with Room for Improvement"
What do you like best about Codility?

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. Review collected by and hosted on G2.com.

What do you dislike about Codility?

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.
