Not at all, their customer aproach should be improved Review collected by and hosted on G2.com.

Codility is a training platform who has many features which are essential for developers at any company, specially to improve development code and product quality. I would like to summarize the main points that Codility currently offers:

1. IDE Platform: Codility offers an online web IDE with a simple environment to code online in real time and to get instant results of the execution of the code written in many programming languages.

2. Coding improvement with challenges: This is the main feature of the platform, providing many different examples, use cases, different project development challenges and high performance development challenges and algorithms (which are required in many companies as a must for joining them). The training and algorithms are very well explained and classified by difficulty, offering many options to improve from lower difficulty to a greater difficulty.

3.Testing: After the execution of the code challenge or exercise, we have the possibility to setup some tests with synthetic data in order to check if the results are the ones expected for the challenge. It is very useful both for companies and for the developer, in order to test for all possible unit test cases, egde cases and high performance tests.

4. Results: After submitting the final coding for the challenge, we are shown a result screen with the execution of all the tests and the possible tests that we were not covering. The platform also shows the execution time of all the tests and how good or bad we did in terms of performance with Big O notation.

5. Additional Platform Training and Options: The platform also provides the possibility to run DEMO excercises, documentation attached to each exercise in order to improve our traning and the possibility to do an exam of professional company coding excercises with a time limit.

I miss a forum to discuss solutions and talk to other people to get feedback. Review collected by and hosted on G2.com.

Codility offers a wide range of coding problems that cover various programming languages, including Python, Java, C++, among others. The problems range from easy to extremely difficult, covering different topics such as algorithms, data structures, and programming logic. Review collected by and hosted on G2.com.

For less experienced candidates, the platform may seem challenging at first, especially due to the complexity of some problems. This can be discouraging for beginners. Review collected by and hosted on G2.com.

Codility offers a wide range of coding problems and automated gradin, making it efficient for assessing candidates' coding abilities at scale.It's especially helpful for quickly filtering candidates based on technical proficiency, with features like real-time code execution and support for multiple progreamming languages. The detailed reports and insights into candidates' performance add significant value for making informed hiring decisions. It is easily navi. The support team did a great job.

the platform's user interface can be somwhat clunky, making navigation less intuitive. Additionally, the focus on algorithmic challenges may not fully represent a candidate's practical coding skills or ability to work within a team. This could lead to a limited view of a candidate's overall potential. I have used the product frequently and it is easy integtration with our platform. The implementation is also easy.

The layout of the testing suite is very elegeant and allows for easy access to all of the necessary information whilst being able to work on solutions all in one go. Other pros such as:

- A separate file allowing you to place custom test cases for questions

- Ability to easily switch between any programming language

- Supports regular IDE keybinds & functionalities such as multi-select + multi-cursor Review collected by and hosted on G2.com.

Lacked the ability to toggle between spaces or tabs for indentation; I was forced to spaces when I prefer tabs so I had to copy my solution out to VSCode and quickly convert it. Review collected by and hosted on G2.com.

- Fonts were very well done. Easy to read the description.

- Online IDE felt familiar to VSCode, nice to work in online

- Ease of switching languages, no code is lost! Review collected by and hosted on G2.com.

- Lack of output (too long) for R

- Lot's of cut off output, makes debugging much easier

- At some point, the browser was lagging because Codility was tracking mouse movements Review collected by and hosted on G2.com.

I found it easy to use even being my first time, I first tried the demo challenge, then took the actual test. It was all straightforward and seamless. Review collected by and hosted on G2.com.

Have demos that actually simulate the test from the company one is interviewing for, probably your team ask clients to post demo tests that actually simulate what their test is like. Review collected by and hosted on G2.com.

The best thing I like about codility is that it makes it easier to understand the problem and it has a good interface. Review collected by and hosted on G2.com.

There's one thing I would like that codility to add excel.. it would be great if codily have an excel tab in which the person can do the do the math and if more needed then they can add some power bi or any visualize tool that can assess more. Review collected by and hosted on G2.com.

It provides support for multiple languages for coding. Easy to use. easy to switch between language. User friednly environment. ease of implementation is goog. well integrated. Review collected by and hosted on G2.com.

You can make the output window floating or movable rather thatn keeping it at a static position. Review collected by and hosted on G2.com.

I find its focus on problem-solving and algorithmic thinking particularly valuable. It provides a range of coding challenges that help users enhance their skills and prepare for technical interviews. Additionally, Codility’s automated evaluation system gives instant feedback, which is crucial for learning and improvement. The platform’s ability to simulate real coding interviews with time constraints and coding environments makes it a useful tool for both developers and companies looking to assess technical skills Review collected by and hosted on G2.com.

Some users may find the interface and user experience less intuitive compared to other platforms, which can make it challenging for newcomers to navigate effectively. Review collected by and hosted on G2.com.
