Codility 2026: Benefits, Features & Pricing

Codility has helped me improve my skills as a developer and as an employer, I use Codility to frequently keep my staff sharp on the job by frequently testing their capabilities.

We evaluated Codility alongside Predictive Index and another technical testing platform. While Codility impressed us with its intuitive code editor and reliable auto-grading, it lacked the broader suite of behavioral assessments we required. Their team was friendly and supportive throughout our trial, but ultimately we chose Predictive Index for its all-around talent insights and another vendor for deeper coding assignments. I can't disclose the name of the competitor.

If you use it, I would suggest the live-code feature where you screenshare and watch the applicant solve one larger problem, preferably one that relates to the job at hand rather than a mensa puzzle. Make sure to review the failing submissions because in many cases, they had it right, but the machine graded them wrong, this could be for many reasons including the structure of the training set they were given was different from that of the testing data. Over half of what our engineers do is debug, interpret existing code, and build infrastructure. None of these things are tested with Codility. If they do pass, they are proficient in at least one element of the job, but not necessarily the rest. I interview any applicant who passes with 30% and always look at their code even if it failed.

Codility helps bridge the challenge of assessing coding skills on objective and efficient grounds. For me, it's like a mentor, which initiates you to first of all think as a software engineer would, maximize your codes, and be considerate of the edge cases in real-world conditions. Providing problems that are similar to those you might encounter in a job interview or while trying to solve especially complex coding problems on the job makes the process of preparing for technical interviews much easier.

First time I used Codility 8-9 month ago in my interview. It was Microsoft interview. Scince that time I some times I join Codility and interested Codility questions.

Codility has really helped us speed up our recruitment process enabling us to do all of our candidate testing pre-interview

My experience was awesome in general. I liked to do the exercises; they're hard enough to get us interested in solving them. My only complain is I'd like to get the final report after an interview to be able to work on my weaknesses. That would be great.
