I enjoyed very much practicing algorithms, getting to know companies through the challenges.
Pros
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.
Cons
The platform suits me very well so I don't have any comments on things I dislike or wish to improve.

Hi Gabor, great to hear that you like using Codility! In case you weren't aware, your license contains plagiarism prevention (the Codility task library is protected and patrolled online for material leaks). However, if you'd like to try out our plagiarism detection features like Similarity Check, please contact us at support@codility.com and we'll be happy to let you try it out.

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.
Pros
It is deployable and easier for HR who don't understand code themselves. The ability to compare to other programmers' skills is nifty.
Cons
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.
Reasons for Choosing Codility
Pricing, ease of use.

Great Experience. Loved the puzzles and exercises
Pros
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.
Cons
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.

Great company to work with for our Hard-Skills assessment
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.
Pros
Codility offers us the opportunity to have a IT assessment part during our recruitment process, which is probably the best in the market available.
Cons
It should have even more tests for each possible position :-)

Very positive.
Pros
Provides a platform to test ones coding/algorithmic skills in interesting problems. The problems are challenging and the feedback provided by the system is helpful.
Cons
I would prefer to see problems tailored to Machine Learning. The problems I encountered in the site are like puzzles to be solved. I would prefer to reflect more Applied Machine Learning.

A New Standard of SaaS for Software Engineer Testing
Exceptional customer service.
Pros
Variety of testing and personalization options ensures that we are efficiently structuring our interview process to gauge engineering effectiveness.
Cons
The UI, while getting better, still leaves somethings to be desired.

We are really liking Codility
Most importantly, codility allowed our organization to dramatically speed up our recruiting process without a loss in quality of screening.
Pros
The software gives us the ability to create a set of coding challenges tailored to the type of hire, with the right degree of difficulty. It also has the capability to detect cheating, which has been very helpful to root out candidates we wouldn't want. After having used the software awhile, we can now gauge how different candidates compare.
Cons
Not much honestly. It's working out pretty well.

Best code assessment website
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.
Pros
The final report when we finish an exercise. It is simply awesome. We are able to quickly verify which area we should work harder to enhance/improve our skills.
Cons
The system blocks the final report if our recruiter doesn't allow us to see it. The feeling is like I will remain blind in front of my weaknesses.

Improvement
It's fast to have a real notion about the capabilities of the candidate. We can get material to go deeper when we're interviewing candidate.
Pros
it's very easy to use. Supports different programming languages and can be fitted to our needs as company.
Cons
Sometimes the ui/ux/layout of the product isn't easy to read the code until the end. in 1 side we have the task and the other the result of it. Would be good if we can improve the live code and also have like a whiteboard to interact with the candidate and solve challenges during an interview or even during the challenge.

Thanks for the feedback AntĂ³nio, great that you like how easy Codility is to use. Since you asked about interview functionalities, you might want to try our CodeLive product which gives you a shared interface with your candidate for solving challenges together or coding together on a whiteboard. Feel free to contact us at support@codility.com and we'll give you a tour!

You can learn a lot about your candidates by giving the same tests. I'm using it mostly with junior developers.

Pros
A really easy to use software. The provided exercises and challenges are intresting.
Cons
The possibility for the user to explicitly tell if he/she used copy/paste from another editor. (Sometimes, one prefer to use his own editor and lately copy the solution to Codility)

The challenges and what you learn along the way

No code-completion in the dev environment, and limited unit testing (which ends up evaluating how good you are riddles and not necessarily engineering)

It was relatively straight forward with interactive guidelines on how to make things work
Pros
Adding test cases is easy and the interface is intuitive. Compared to some other websites the instructions are clear cut and I had no problems when using it.
Cons
Error messages can be vague. I can't recall since my last challenge was a few months ago, but I don't think the error message pointed me towards a specific line in my code.

Online coding platform
Pros
I was invited to give an online test on this platform. I liked the practice problem that they have provided with every detailed explanations as well. The test cases for each problems are also very diverse.
Cons
When we are doing a problem, every easy test cases are provided. Once we submit the solution, it evaluates on a wide range of test cases depending on correctness and performance. But these test cases are not visible to the programmer. We can't see them for future reference purpose. It just show that this case failed.
