Codility Developer Training Reviews & Product Details

It works as expected. It's the best tool to learn core code concepts. Review collected by and hosted on G2.com.

Codility has many interesting challenges. I didn't do all yet, but there were no flaws at all so far. Review collected by and hosted on G2.com.

Codility has good explanations 4 concepts Review collected by and hosted on G2.com.

Lack of interactive exercises 4 concepts Review collected by and hosted on G2.com.

The complexity of the question and the wide coverage. Review collected by and hosted on G2.com.

The question should be in such a way that it gives the learner an idea of the concept being tested for further studies in case one fails. i.e after the scores are out one should get the topic to review for each question. Review collected by and hosted on G2.com.

The lessons and challenges. It is good way to improve your programming skills. Review collected by and hosted on G2.com.

Description is quite long and sometime it makes programmers confused and if programmers do not read it carefully, they could not pass the lessons. Review collected by and hosted on G2.com.

Some of the lessons include techniques for efficiency which were new to me, so combined with writing real code that has to run this was an excellent learning experience. Review collected by and hosted on G2.com.

I wish I could set a default programming language - I use Python at work so I use it for all my Codility exercises. However, Codility always starts with Java as the programming language, both in the problem description page and when starting to solve the problem. Review collected by and hosted on G2.com.

The practice problems solved are thought-provoking. Definitely a great starting point if you are appearing for coding assessment tests. Review collected by and hosted on G2.com.

Should have included more practice problems categorized with more difficulty levels. Review collected by and hosted on G2.com.

The challenges help me to improve my coding skills Review collected by and hosted on G2.com.

There's not a important thing to mention in this point. Review collected by and hosted on G2.com.

I like the highest standard of quality that Codility has maintained throughout their platform. I am amazed by their quality rich online programming environment with lots of programming languages options and the concise and well thought out programming challenges and tasks. They have also provided lessons and training tasks on several types of algorithms on their website to help programmers improve and evaluate their programming skills. Review collected by and hosted on G2.com.

The only thing that I think needs some improvement is that they should add a few more lessons to cover all the typical algorithms that are common in competitive programming. Review collected by and hosted on G2.com.

The Performance Assessment is one that I haven't seen before and in this system, it challenge us to think more about performance. Review collected by and hosted on G2.com.

The test cases used by the assessment not displayed. Review collected by and hosted on G2.com.

Codility is really good for improving your coding skills when it comes to learning to apply the right, efficient algorithm to the problem at hand, and also writing correct code that covers all edge cases. The detailed results and statistics Codility presents after submitting a solution are also great, and such feedback helps you improve faster. Review collected by and hosted on G2.com.

I would like it if the types of tasks were more diverse. It seems for most tasks, the focus is on the algorithmic aspect of the problem, i.e. finding and applying an efficient and correct algorithm. Perhaps tasks could be designed that aren't so much about finding a good algorithm but more about testing one's OOP skills or some other skill important in programming. For example, design a task that requires one to implement a callback mechanism; This can be realized multiple ways (function pointers, polymorphism, etc.). Sure, the solution of such a task might be harder to evaluate and score, but I imagine you could still score it on e.g. run-time performance and/or memory footprint.
