Tech technical assessment platform for tech hiring teams

About Codility

Codility is a technical assessment platform which helps tech recruiters and hiring managers assess candidate coding skills via online coding screening tasks. Codility supports hundreds of programming tasks and multiple languages, and features real-life scenarios with varying levels of difficulty.

Codility provides an industry-relevant skill library for Frontend, Backend, QA, Data Science, Big Data, Blockchain developers, and more. Users can also create custom tests for their team. To ensure test integrity, Codility offers plagiarism protection and detection functionality. Codility’s pre-screening tests are designed to help recruiters identify and set-up interviews with only the most relevant or qualified candidates.

Codility also allows users to hold real-life tech or coding interviews online through their solution, CodeLive. With CodeLive, users can run unit tests and compile code collaboratively with potential candidates. CodeLive supports video and voice connection, as well as individual and group interviews, and full code playback. Codility’s CodeTrain product supports learning and development, helping users improve their team’s programming skills and coding knowledge through custom training tests.

Codility integrates with a number of applicant tracking solutions, including Lever, Greenhouse, Jobvite, SmartRecruiters, and more.

I enjoyed very much practicing algorithms, getting to know companies through the challenges.

It is a well organised, polished platform for coding skills evaluation. The lessons and challenges provide good content for user practice and the summary section helps to understand the areas the user is going well and areas to improve.


The platform suits me very well so I don't have any comments on things I dislike or wish to improve.

Easy to use. I can manage a lot of candidates and different software languages.


There is not enough task. My package is not contains plagiarism check.

Not an adequate test for most engineering roles.

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.


It is deployable and easier for HR who don't understand code themselves.
The ability to compare to other programmers' skills is nifty.


Many of the problems are not completely presented (I.E. there are other factors that are not mentioned which would influence the code, so applicants who submit overly-thorough code will actually fail because the machine didn't like their answer.. it is a guessing game)

20 minute time limits to solve an algorithm problem are NEVER the case in real life.

Programmers do not work off memory, they work off documentation-- codility does not test on use of frameworks or libraries, only math concepts.

The IDE is limited, will delete the applicant's code if they switch languages momentarily.

Great Experience. Loved the puzzles and exercises

Reviewed on 2018/07/27


A great coding platform, it's easy to use with a clean interface. I've enjoyed the exercises available. The problem statement and examples have great clarity without being too wordy or short. I've taken a couple of tests for companies who used Codility for screening. I've had great experience writing code, testing, putting in my own test-sets all available in the platform.


The software is pretty much self contained and clean. There isn't much I would complain about. I would love to see more exercises/puzzles.

It has been a great first few months working with Codility! The staff, has been very patient and generous helping us out, doing more than we could ask for! Great customer experience up to now and hopefully it will always continue like this for the future as well.


Codility offers us the opportunity to have a IT assessment part during our recruitment process, which is probably the best in the market available.


It should have even more tests for each possible position :-)
