Codility Reviews

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.

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.

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 :-)

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.

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.

Ease of use for candidates and hiring managers

Time consuming to 1st set up the system for use as you need to create all of your tests

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.

Not much honestly. It's working out pretty well.

I like to take tests on Codility, it's clear about requests and also it helps you through the process.

no cons about Codility, why would I have any?

- Getting a sense of pair programming with interviewee
- Enables screening candidates' coding ability

Not sure yet ... I've not explored all of it so far.

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.

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.

Variety of testing and personalization options ensures that we are efficiently structuring our interview process to gauge engineering effectiveness.

The UI, while getting better, still leaves somethings to be desired.

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.

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.

The ease of use and the candidate experience.

That I don't have enough candidats to use it more :)

A really easy to use software.
The provided exercises and challenges are intresting.

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)

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.

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.

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.

it's very easy to use.
Supports different programming languages and can be fitted to our needs as company.

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.

i like the lesson. We can read the material before we can test our capability in mini test or challenge

in my first impression with this software, it's very user friendly. Not need many time to adapt with this software
