Choosing and setting up IDE platforms for multiple programming stacks is very easy and convenient for the candidate.

I appreciate Codility's ability to add our own questions, which allows us to tailor the assessments to our specific needs with custom questions based on real problems we face. The whiteboarding feature is valuable, and I love that I can view the candidate's screen during interviews without requiring them to share it in a call. The platform is also simple to set up, contributing to its ease of use, which was a significant reason for switching from HackerRank.

Honestly, the best thing about Codility is how much time it saves me. I use it regularly for interviews, and it's basically plug-and-play. The fact that I don’t have to spend hours inventing and testing coding questions is a lifesaver—their built-in question bank is huge and actually relevant, which saves our engineering team a ton of hours every single week. The coding IDE itself is great. It’s super clean, doesn't lag (great performance), and it's technology-agnostic, meaning candidates can code in whatever language they're comfortable with while I get a smooth, platform-specific view. The AI features are another huge win. Instead of me sitting there trying to play detective, the AI agent monitors the solutions, checks for candidate integrity, and flags any weird behavior with alerts. It lets me focus on how they actually solve the problem rather than worrying about cheating. Getting it set up and onboarding the rest of the team was frictionless, and honestly, the ROI speaks for itself when you calculate how many engineering hours we get back. The integration experience has been practically seamless. We connected Codility directly into our Applicant Tracking System (ATS), and it has completely cleaned up our daily workflow. Instead of jumping back and forth between different browser tabs to copy-paste data, everything happens right inside our main recruitment tool. We can trigger a Codility test invite automatically as soon as a candidate moves to the screening stage, and once they finish, their scores and the full report link sync straight back to their profile.
