Codility Reviews & Product Details

Codility has predefined modules - multiple choice as well as tasks which allow scripting in common languages such as Java and Python. It is therefore easy to create a robust test, but as you can also create your own testing tasks it's quite flexible. GUI is easy to use and portable as it's browser-based.

Not sure about the scoring of the scripting modules, seems a bit inconsistent, if one line of code e.g. defining a variable works then marks are allocated, but complete scripts with a minor syntax error score 0. Review collected by and hosted on G2.com.

Response time and interfaces are nice. The problems are also very clever. Review collected by and hosted on G2.com.

I would prefer for java to have compilation errors shown without running the code if possible. Review collected by and hosted on G2.com.

The only thing that took any time was setting up the right set of questions and that's only because I wanted to be sure we were doing a good job to find the best candidates. Codility even provides sample question and stats on how people have fared on that question from the broader user base. Very easy to ramp up recruiting process efforts.

I had a little bit of trouble with all the features being presented quickly and I didn't know what I wanted to pick. In the end I just needed to try a few problems and then get more familiar with the other features. Review collected by and hosted on G2.com.

It lets you run your code right in the browser, and allows you complete tasks easily. You can get started quickly. It supports many languages. It lets interviewers see exactly how you solved the problems step by step. Review collected by and hosted on G2.com.

It doesn't support the latest version of Swift. It doesn't offer information besides stack trace for errors. It has no syntax highlighting. Review collected by and hosted on G2.com.

Codility provided the best environment to test our ability to code and implement logic. What I liked the most was that the Codility doesn't only check the code according to it's output but also the processing efficiency and time constraints. Review collected by and hosted on G2.com.

Output from large heap of data can be seen only after the submission so we may never know if the code works with the given time constraint and processing efficiency unless we have submit the code. Review collected by and hosted on G2.com.

The ease with which you can create a panel of tests to model a given technical role, and then look in detail at not just how a candidate handled a task, but also the steps they took to get to their solution. Review collected by and hosted on G2.com.

There are a few places in the interface where I believe some improvements could be made. However, not only are the staff very open to constructive feedback, they are quick to take action on that feedback. One suggestion I made regarding evaluation of tests submitted without changes was implemented in less than a week after I made it. Review collected by and hosted on G2.com.

The testing environment is very good. It's simple, organized and easy-to-use. There is an extensive language support and their Integrated Editor and Console is very helpful in writing and testing the code within the website. There is even support for writing your own test cases which is a lot helpful too. Review collected by and hosted on G2.com.

The results after a test are not very verbose - they do not show the good/bad parts of your performance in the test, thus you never get to know what you did that worked well, and what didn't. A detailed summary would have been appreciated. Review collected by and hosted on G2.com.

I especially enjoyed being able to create tests and to see a pool of candidate scores. The live code room is also a game changer for remote interviews. Review collected by and hosted on G2.com.

The user interface can feel clunky and takes some getting used to. Review collected by and hosted on G2.com.

That we can compile and test our code before submitting Review collected by and hosted on G2.com.

Not all test cases are shown before. I am not sure but may be it adds to pressure. Review collected by and hosted on G2.com.

I want to point out the easily creation of the tasks and managing them.

All together makes it a tool usable for different use-cases. Review collected by and hosted on G2.com.

There is nothing what I can think of. I received only positive response from my team. Review collected by and hosted on G2.com.
