# Codility Reviews **Vendor:** Codility Ltd **Category:** [Technical Skills Screening Software](https://www.g2.com/categories/technical-skills-screening) **Average Rating:** 4.6/5.0 **Total Reviews:** 902 ## About Codility Codility is a technical assessment platform built on documented assessment science. It helps engineering and talent teams evaluate technical skills for hiring and map verified capabilities across existing workforces. Every assessment is designed by occupational psychologists, validated against an Engineering Skills Model drawn from 30+ international frameworks, and monitored for adverse impact at every measured cut score. AI has changed how engineering teams deliver. Organizations need signal on who can build in this environment, backed by methodology that holds up when questioned. Codility provides that signal across three workflows: screening candidates with validated technical assessments, running structured live technical interviews, and verifying skills across internal engineering teams. For screening, Codility provides a task library of 1,200+ validated assessments covering real-world work simulations, algorithmic challenges, SQL, and project-based tasks across 80+ languages and frameworks including Python, Java, JavaScript, TypeScript, C#, Go, Rust, Kotlin, React, Angular, Vue.js, Spring Boot, Django, Terraform, Kubernetes, and TensorFlow. Scoring is automated on supported task types with detailed candidate comparison, configurable time limits, and role-specific weighting. Assessments are reviewed by occupational psychologists and follow documented methodology with auditable scoring. For live technical interviews, the platform provides a shared VS Code environment with terminal access, sidecar services for databases, caching, and message queues, a collaborative whiteboard, and full session transcript and recording. Engineering teams evaluate candidates in a real development environment. Talent teams get a repeatable process with rubric scores and session playback after every interview. Organizations control how AI is handled in every assessment. Teams set their AI posture role by role: provide candidates with a monitored AI assistant and review how they prompt, evaluate, and debug with AI, or restrict AI access to evaluate core technical skills independently. Both approaches use the same set of controls and produce a reviewable record of all AI activity. One platform supports AI collaboration assessment and unassisted evaluation with full auditability. Integrity controls are layered to support defensible hiring decisions. These include identity verification, behavioral signals, risk scoring, similarity detection, paste volume measurement, and automated follow-up questions designed to verify understanding. Follow-up questions are deliberately not scored, to avoid introducing bias. When AI is enabled, reviewable AI activity helps teams distinguish between a candidate's own work and AI-assisted output. All signals produce a defensible record for human review. Skills Intelligence provides verified technical skills visibility for existing engineering teams. Organizations use it to identify capability gaps, benchmark skills across teams, and support workforce planning with assessed data rather than self-reporting. Hiring assessment and internal skills verification share the same validated methodology, giving organizations one assessment science foundation across the full talent lifecycle. Codility is SOC 2 audited, ISO 27001 certified, GDPR and CCPA compliant, WCAG 2.2 AA accessible, and aligned with EU AI Act requirements for high-risk AI classification. Assessments follow documented methodology structured to APA Standards, with a 76-page Technical Manual, adverse impact data at every cut score, and an explicit posture: no AI or ML is used in automated hiring decisions. Data is hosted in either EU or US regions. The platform integrates with 20+ applicant tracking and scheduling systems (ATS) including Greenhouse, Workday, SAP SuccessFactors, iCIMS, SmartRecruiters, Lever, Eightfold, and Ashby, with 80+ HRIS integrations for Skills Intelligence. It supports SSO via SAML 2.0 and offers API access for custom workflows. Founded in 2009, Codility is used by engineering and talent teams at Barclays, BMW, Deutsche Bank, GitHub, Samsung, SpaceX, and other organizations evaluating technical skills across both AI-assisted and traditional engineering workflows. ## Codility Pros & Cons **What users like:** - Users find Codility to be **easy to use** , with a clean interface and seamless setup that enhances the hiring process.

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. **What do you dislike about Codility?** 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. **What problems is Codility solving and how is that benefiting you?** Codility is mainly solving the problem of unfair and inefficient technical hiring, where companies rely too much on resumes or interviews that don’t truly show a developer’s real skills. Instead of guessing someone’s ability, Codility gives candidates real coding tasks and automatically evaluates how well they solve them, making the process more objective and skill-based . It also helps companies filter candidates quickly and avoid bad hires, which saves time and cost. For me, this is beneficial because it creates a more level playing field - I get judged on what I can actually code, not just what’s written on my resume.

Additionally, I found the initial setup to be easy, which was a big plus. **What do you dislike about Codility?** I'm not sure if candidates are using AI on another screen to come up with answers, and I'm not sure if Codility can prevent it. Codility could implement controls to prevent interviewees from copying, pasting, or moving out of the window during an interview, or lock down the ability to move to other tasks until the interview is over. **What problems is Codility solving and how is that benefiting you?** I use Codility to conduct programming interviews, allowing me to have candidates write code, compile, and see results in real time, which helps me assess their knowledge depth. **Official Response from Christopher Greco:** > Hi, thank you for the thoughtful review. I'm glad the real-time coding and compilation experience is helping you assess candidates effectively. The concern you raised is exactly the kind of thing we've been focused on. In November 2025, we launched Live Proctoring Signals in Codility Interview in Public Preview. Interviewers now receive real-time notifications whenever a candidate switches browser tabs, loses browser focus, attempts to copy the task description, or pastes code from an external source. These events are captured in a live integrity timeline throughout the session, giving you a clear picture of candidate behavior as the interview unfolds. So while we can't fully lock down a candidate's machine (they're on their own device, after all), you now have immediate visibility into the exact behaviors you described, like moving out of the window or pasting in code from elsewhere. That awareness puts you in a much stronger position to probe further or adjust the conversation in the moment. If for some reason you don't seem to have these features available to you, please reach out to our support team or directly to me at g2@codility.com. We'll be happy to help.

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. **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. **What problems is Codility solving and how is that benefiting you?** We have a big ammount of technical assessments happening everymonth, which led us to look for a tool that would standardize the way we interview and assess candidates, this way we would ensure our bar is aligned. ### 22. Intuitive Platform for Coding Tests with Real-Time Challenges **Rating:** 5.0/5.0 stars **Reviewed by:** Vikash Y. | Software Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** April 13, 2026 **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. **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. **What problems is Codility solving and how is that benefiting you?** I use Codility for automatic evaluation and an anti-cheating environment. It evaluates skills like debugging and refactoring with real enterprise questions, not just algorithms. **Official Response from Christopher Greco:** > 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. Christopher Greco Head of Product Marketing, Codility ### 23.

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. **What problems is Codility solving and how is that benefiting you?** Codility enhances interaction with interviewees, resembling Visual Studio for coding tasks, and facilitates sharing problem statements across the organization, but it needs improvement in handling precomputed tables for SQL tasks to better evaluate interviewees. ### 27. Smooth, Hiccup-Free Testing Experience **Rating:** 5.0/5.0 stars **Reviewed by:** Bibek L. | Software Engineer, Enterprise (> 1000 emp.) **Reviewed Date:** April 15, 2026 **What do you like best about Codility?** The test environment was smooth. I didn’t encounter a single hiccup throughout the test. **What do you dislike about Codility?** It didn’t have camera proctoring, which makes the test more prone to cheating. **What problems is Codility solving and how is that benefiting you?** Codility proves that I am competent with a skills, which makes me confident in my role **Official Response from Christopher Greco:** > 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. Christopher Greco Head of Product Marketing, Codility ### 28.

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. **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. **What problems is Codility solving and how is that benefiting you?** I use Codility to objectively assess candidate technical skills, providing instant syntax highlighting and feedback through VM-run code, which reveals errors precisely. It boosts my confidence in evaluations by highlighting issues, aiding in probing candidates and understanding their debugging process. ### 31.

Great Real-Time Interaction, but Coding UI Could Be More Intuitive **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Enterprise (> 1000 emp.) **Reviewed Date:** October 28, 2025 **What do you like best about Codility?** 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. **What do you dislike about Codility?** 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. **What problems is Codility solving and how is that benefiting you?** I appreciate the screening features that help determine whether someone actually wrote the code themselves or simply copied and pasted it. In the industry, it's important for us to know if code was genuinely written or just taken from the internet. Additionally, the feature that flags how long participants were inactive is also quite useful. ### 36.

Practical, Evolving, and Engineer-Friendly **Rating:** 4.0/5.0 stars **Reviewed by:** Abhinav K. | Senior Software Engineer, Information Technology and Services, Enterprise (> 1000 emp.) **Reviewed Date:** July 09, 2025 **What do you like best about Codility?** 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. **What do you dislike about Codility?** 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. **What problems is Codility solving and how is that benefiting you?** Codility has helped us streamline our hiring process by giving us structure around technical screening. It allows us to evaluate not just correctness, but clarity, logic, and decision-making in code. It’s also a great collaboration tool for live interviews—debugging with candidates, following up on edge cases, and getting a feel for their communication and problem-solving style. And features like the timeline view, detailed reports, and tab-switch monitoring have made our candidate evaluations more granular, helping us make better decisions and reducing bias. ### 45. Easy to use **Rating:** 5.0/5.0 stars **Reviewed by:** Sagar A. | Technical Specialist, Small-Business (50 or fewer emp.) **Reviewed Date:** July 18, 2024 **What do you like best about Codility?** 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. **What do you dislike about Codility?** 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. **What problems is Codility solving and how is that benefiting you?** It helps to improve my assessment skills, practicing different kinds of problem statements which leads for my career advancement. ### 46. Best place to practice coding **Rating:** 5.0/5.0 stars **Reviewed by:** Surendra K. | Senior Software Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** August 25, 2024 **What do you like best about Codility?** It's great to see how Codility keeps evolving. Building on my previous positive experiences, I've recently been impressed by a few new things that make the platform even better: - The Introduction of Real-Life Tasks: What I really like now is the move beyond traditional algorithms. They have introduced tasks that mirror actual day-to-day work for a developer, like debugging an existing block of code, refactoring it for better performance, or working on a small feature within a larger project. This feels much more practical and relevant to the actual job, making the assessment a more engaging and fair evaluation of my real-world skills. - Enhanced AI-Powered Assistance: The platform's autocompletion and code-writing assistance have become noticeably smarter. It’s not just about finishing a line of code; it feels more like an AI pair programmer. It provides more context-aware suggestions and helps catch silly mistakes on the fly, which lets me focus on the core logic of the problem rather than getting bogged down by syntax. This makes the coding process smoother and faster. - Improved Candidate Feedback and Insights: After completing a test, the feedback provided seems more detailed than before. Instead of just a score, there's a better breakdown of performance, correctness, and efficiency. Seeing this granular feedback helps me understand my strengths and pinpoint specific areas for improvement, which is incredibly valuable for my personal development. While I've always appreciated the platform's stability and support, these recent enhancements show a commitment to creating a more modern and practical assessment experience. It feels less like a generic test and more like a simulation of a real coding environment, which is something I genuinely like. **What do you dislike about Codility?** High-Pressure Environment: The timed nature of the tests, combined with camera and screen monitoring (proctoring) in some cases, can create a stressful and unnatural coding environment. This pressure can hinder performance, not always reflecting a candidate's true ability to solve problems in a real-world, collaborative setting. IDE Limitations: Although the built-in editor is good, it can feel restrictive compared to the fully customized local IDEs (like VS Code or IntelliJ) that developers use daily. The lack of familiar shortcuts, extensions, and debugging tools can be frustrating and slow down the coding process. **What problems is Codility solving and how is that benefiting you?** It provide a faire way to give apporchunity to test the candidate skills. ### 47.
