Simple IDE and the theme. I also appreciate the compilers in there. Review collected by and hosted on G2.com.

The test cases. It would be good if we can create our own test cases or change the inputs during run time Review collected by and hosted on G2.com.

The fact that most jobs i apply to, have coding tests conducted on codility. I needed to prepare and understand the nature of tests, the correctness and performance criteria and mostly the edge cases that are not in the requirements.

The lessons helped me practice and i got better at getting good score with time which eventually led me to landing a job. Review collected by and hosted on G2.com.

Sometimes the test fail but there is not much information on what was the exact input to the module that made the test fail. The lessons are a bit dry and most of the times a bit irrelevant, i would appreciate if more practice lessons could be added. Review collected by and hosted on G2.com.

The platform provides realistic coding challenges. Not just useless algorithms. Review collected by and hosted on G2.com.

Nothing. I think its a great platform that blends useful, realistic challenges with your classic Leetcode style, algorithm-based challenges Review collected by and hosted on G2.com.

Codility provides an opportunity to hone a very specific set of skills that are relevant to a certain advanced subset of software developers. Review collected by and hosted on G2.com.

The codility tests and so-called lessons are geared towards advanced software development concepts that are most relevant to developers who would be writing extremely efficient, algorithmic and mathematical code. If you are a seasoned business software developer you will likely find that these tests and lessons have very little relevance to the type of code you have spent your career writing. Using this type of coding to measure the skill of a business software developer is inappropriate. If you write scientific, mathematical, algorithmic code for use in advanced applications like video games, 3D modeling, operating systems, device drivers or artificial intelligence, you will likely feel right at home here, and will be able to easily complete the tests and lessons. If not, you will probably struggle. In one example, the developer is tasked with solving three problems within 90 minutes. Your solution will be graded not only on completeness, but also on efficiency. So if you’re not familiar with concepts like prefix sums or tricks to traversing arrays and detecting patterns, and using other mathematical hacks to avoid traversing multiple nested arrays, you’ll probably struggle. The questions themselves are tough and verbose and will take 10-15 minutes just to read. You now have a mere 45 minutes to write three small programs, and you will not be provided any means of measuring efficiency until you submit your solutions, at which point you cannot go back. The built in editor is about as helpful as writing code in notepad, so be sure to have your IDE ready to write, test and debug your solutions because the built-in compiler is essentially useless and in most cases, doesn’t even tell you what’s wrong or where. And don’t even bother attempting the test in VB, as their implementation of VB is extremely limited, even when compared to their C# implementation. Want to use LINQ or even a generic collection, like a dictionary in your solution? You can’t do that in VB, but you can in C#, so cut to the chase and write your solution in C#, even if VB is your preferred language. If you’re looking to learn, the Codility lessons are not very good learning tools. A lesson would help you understand how to improve your solution. Codility lessons do not. They tell you that your code failed certain test cases, but won’t tell you what the test case was, or how you could improve. Review collected by and hosted on G2.com.

The platform is super smooth. Didn't encounter a single bug or glitch during my whole experience. Review collected by and hosted on G2.com.

This is not what I dislike but I do want you guys to have it. There should be a basic start to actually boast up a guy struggling in logic building because now the level keeps on going up at a faster pace than you expect. Review collected by and hosted on G2.com.

I like the ability to practice what I will be tested on. In computer science, there is so much to cover that it is good to refresh on the basics for interviews. Review collected by and hosted on G2.com.

I have no complaints about Codility. It is overall a good tool for finding jobs. Review collected by and hosted on G2.com.

The simplicity to start a test. Information is clear and all you need is right in the same screen.

Test assessments are well detailed and give you the right view on which you can plan any improvements. Review collected by and hosted on G2.com.

As for an online tool, we could see some database related tests more often. Review collected by and hosted on G2.com.

It's a really good platform to practice algorithm and learn how to solve interview problem Review collected by and hosted on G2.com.

It'll be better if I can choose my default language. Review collected by and hosted on G2.com.

There are a lot of things which are great. Tasks are understandable and have examples which is very useful for me as for non native speaker. Code editor works without any problems(or at least I have not faced with them). Review collected by and hosted on G2.com.

I would prefer to have an option to use my own code editor and just pull changes by git. This feature wold be very useful. Review collected by and hosted on G2.com.
