A great developer assessment tool
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.
Pros
I have used Codility as a developer as well as an employer and I can tell you that it is a great assesment tool. One of Codility's key advantages is that it enables employers to quickly and effectively assess the coding abilities of numerous job applicants. Candidates can work at their own pace through the online coding tasks on the user-friendly website.As a developer, I use Codility to assess my coding abilities and learn new programming paradigms in the process.
Cons
Some of the things which I would like them to work on is an offline mode. The complete dependence on the internet may limit some users from enjoying its features. They should also make it such that tests are optionally timed, many times, developers are not able to complete the tasks within the short timeframe.

Codility’s Strengths and Areas for Improvement
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.
Pros
I recently attempted Codility. Honestly, I would say it was some mix of both challenge and insight. The platform is quite well designed with a smooth interface to coding, clear problem statements, and real-time feedback about performance.
Cons
Probably, one of the issues with Codility is that the tests can sometimes appear a little too edged on the edge cases. I think it might be frustrating for developers more accustomed to solving practical, everyday problems. In some cases, very severe time limitations and scoring systems really add unnecessary stress on candidates. Instead of exploring creative solutions, candidates focus more on trying to get a qualifying score.

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 Switching to Codility
Pricing, ease of use.Response from Codility
Dear Mark, thank you very much for your feedback!
We are sorry to hear that your experience with Codility didn't meet your expectations. We'll strive to do better in the future!
Algorithmic tasks are only a small part of our task library. We also offer a lot of real-life tasks, including the ones where candidates need to fix the bugs in existing code or rewrite the code to improve the application performance. Moreover, our Partnered Tasks service allows you to add your own real-life tasks to our platform.
If you're interested in learning more about all sorts of tasks we offer to our customers, please reach out to [email protected]. We'd also be happy to hear more about what kind of tasks or technologies are missing in our library, so we can add them ASAP.

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.

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.

Coding for Technical Assessment
Pros
Codility is very easy to setup and user friendly. And one of the few things I really liked is that, for the monthly plan, the number of candidates to add for assessment is unlimited unlike other platforms that would usually have 30 slot Max.
Cons
Can't really think of one, its a great tools for company that hires Tech talents in volume.

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.
Response from Codility
Thanks for the feedback António, 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 [email protected] and we'll give you a tour!

My Codility
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.
Pros
It's easy of use and I can reach evey old questions easily because questions listed near by near. And I can connect to start time for taking my test again if time is already expired. And resolving time period for every test questions is long, in 1-2 month every body can connect and resolve problem and earn certificate for every resolving problems.
Cons
For every problems I trying use my computer idea before adding my code to Codility because it apsent idea feature, ex. autocomplete. And I do my test cases by myself(It's a bit takes time ) in my idea. I would like Codility before give the several tests cases which users can copy to add their idea.

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.
Response from Codility
Dear Ashish, thank you very much for your feedback!
We're happy to hear that you had a positive experience with Codility :)
There are multiple reasons why some of the test cases are hidden. Some of the test cases are rather complicated, which might create some confusion, and we strive to provide candidates with the best experience possible. In addition, we don't make all test cases visible to candidates because this would encourage them to hardcode a solution rather than writing one that will scale in a real-life job related scenario.

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.

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.

Pros
Having test input/output is quite easy and accessible. Interface is readable.

When implementing objects from other libraries, it didn't add library automatically. And you did not notice that you have to import library before runtime.

Great product, very helpful!
Pros
This is a great place for coders to prepare for interviews, and for employers to define an effective hiring process.
Cons
No cons I can think of. This is a con of this survey. Why do you force me to write a minimum when I'm just happy with the software?
