Codility Developer Training Reviews & Product Details

I like the simplistic yet powerful design of the website, how easy it was for me to just start solving challenges. I also really like the automatic and instant check of the code - I agree, it might look to robotic, but in a way, the ultimate code must compile and run on all cases - so it's a much greater pleasure to see 100% score.

The navigation is a bit clunky: when I finish the answer to the question in the lessons section I would like to immediately be able to go to the list of remaining questions. Review collected by and hosted on G2.com.

most of my interview was on it so it is only logical to train and learn on it

also it has very good PDF tutorial that make understand the concept not just one problem at time Review collected by and hosted on G2.com.

i do not like it does not save my answers may be i want to review it later it help more just remember my code

also the tutorial all made with python it will be great to have it in anther language such as java but it is easy to understand it and make your own version Review collected by and hosted on G2.com.

The interface is very clean and intuitive, it is easy to get going on your first try. Review collected by and hosted on G2.com.

There is nothing I dislike until now, maybe I will revise it after using it more. Review collected by and hosted on G2.com.

I like no flamboyance, no themes etc approach. UI is so basic that it does not distract but it is fully functional. Review collected by and hosted on G2.com.

They could have more programming languages especially from different paradigms like Smalltalk, Lisp etc. All they have are similar imperative algol-like languages. That can be improved. Also more questions in lessons section needed without blowing it up with trivial or subpar questions. Review collected by and hosted on G2.com.

Coding and thinking of algorithms to optimize the performance. Review collected by and hosted on G2.com.

Nothing much. For a browser based environment it does pretty well. Review collected by and hosted on G2.com.

Interface is really good implemented. Easy to switch programming language. Most of proposed problems are nice even if some have really university style approach. Review collected by and hosted on G2.com.

Is a perfect instrument for learning coding but somehow not the best to get interviewed with. Making excercises in this automated way is not really representing the candidate preparation. Review collected by and hosted on G2.com.

The training questions give me the place to improve my algorithms coding skills and strategy thinking of problem solving Review collected by and hosted on G2.com.

it's hard to know where to improve especially in terms of performance tests, would be great if the training questions would provide information or help for developers to find the source to learn the new skills required to improve the coding skills. Review collected by and hosted on G2.com.

You can see detailed result of your submitted source. For each lesson, they provide pdf file for learning material Review collected by and hosted on G2.com.

It didn't save our submission result and source code so when you want to retake the test, you need to start from 0. Review collected by and hosted on G2.com.

I like the depth of detail with which the solution is analyzed and the possibility to add test cases Review collected by and hosted on G2.com.

I think I would have appreciated more the possibility of having an integrated development environment Review collected by and hosted on G2.com.

It has a great platform that allows you to do exercises in any programming language and has its integrated compilers which give it great value when it comes to testing the skills of a developer. What most caught my attention is the large number of languages handled by the application allowing the developer to choose the language with which he feels most comfortable to solve the exercise.

I would like that as it handles different types of programming language, it will handle different languages, the platform only handles in English and for those who do not handle English it is a bit difficult to solve the exercises. I would like much more if at least I would use that option to change languages. Review collected by and hosted on G2.com.
