Codility Developer Training Reviews & Product Details

I'm a .Net developer, some time ago one of my colleagues recommended this resource to me as an opportunity to look at my skills in programming algorithms. So, what I can say, the first thing I would like to do is thank the entire team who works hard and expends lots of energy and effort making this project very interesting. The tasks are very interesting and sometimes very difficult, you have to spend much time solving a problem, reading additional materials. In general, for those who are bored and want to see how creatively and quickly they can think, I advise! Review collected by and hosted on G2.com.

Editor, the latter is very poor in terms of functionality, in case when you are trying to pass tasks as an interviewer you might have a problem with code style, in this case, the editor doesn't allow using tab formatting a code, as a result, you have to type space a lot of time.

The feedback is detailed and strict. Which forced me to read deeper about certain concepts. Which helps with growing as a developer. Review collected by and hosted on G2.com.

On challenge I tried I did not get it right. Even today I don't even know what I did wrong. It compiles well and it passes the default test case and the test case I can think of. But when I submit, I received 7% and I just don't know what am doing wrong. So I don't enjoy that I have no solution to learn from. I just have to take my lose and move on in this case.

Ability to run tests on each task, very clear instructions on most exercises, nice supporting lessons Review collected by and hosted on G2.com.

Exercises are mostly too academic. If you are a student that just finished your degree, you'd probably be fine. If you are a senior developer that studies practical problems, however, you are in trouble Review collected by and hosted on G2.com.

The problems and all the languages accepted. I have a lot of problems to train my skills before I've do a test, the result of a test has info about the complexity of your solution and this for me is a major feature. I really enjoyed the experience using codility in my code interview, and I want to use it more times in the future. Review collected by and hosted on G2.com.

Some questions in the train area have some small errors and this decreases the overall experience. The worst problem I found is that the language JavaScript sorts numbers in a lexicographic way even if the type is number, and this reduced my score from 100% to only 40%, and this in a code interview is something unacceptable. I think the best solution for this type of problem is to add some preprocessor language like TypeScript or CoffeeScript, since those languages have tools that test this and make this type of error harder to occur or at least easier to be found. I hadn't tested other languages but I think this is the only problem I found that I dislike the most. Review collected by and hosted on G2.com.

Always generate a report to show the coding result. Review collected by and hosted on G2.com.

Can't set default mode, which is always dark mode, I have to change to light mode every time. Try to guide me through the interface every time I login, I am already an experience user, so no need to guide again. Can't show error test case details. Review collected by and hosted on G2.com.

• Immediately know if the solution works or not due to the fact that the task has a compiler, input and tests for validation

• Cheat detection Review collected by and hosted on G2.com.

• Writing code in text form in a cell is inconvenient, e.g. no tabs

• When adding a Upload type Task, it might be possible to set a time limit higher than 180 minutes

• The deletion logic is in the folder, individual tests cannot be deleted / closed (at least in the standard role). When you delete a folder, the tests under it simply move to the "main" folder, i. did not understand how to complete the test, so sharing a public link via email seems to be a better option at the moment because there is an expiration date.

• Sessions - relatively pointless and slow Review collected by and hosted on G2.com.

The all-around topic for programming fundamentals refreshers. The selection of programming languages to practice with. The ability to determine your own 'test case' should you wanted to create your own experiment when either practising/taking the real test. The UI seems friendly to use for all users. If I remember correctly, I think you can *switch the background from lighter to darker (*This is nice. I prefer a darker background to improve the readability of the code that I have written!)

There is a lack of dedicated SQL refreshers lesson. Sometimes the reading materials do not effectively explain the fundamentals of the programming tasks of the lessons. Review collected by and hosted on G2.com.

I like the ability to run custom tests and write to console Review collected by and hosted on G2.com.

I like to see the full set if hidden tests to help understand some failures I have encountered. Review collected by and hosted on G2.com.

The reading material provided for each lesson / topic included very concise and useful information Review collected by and hosted on G2.com.

Not as many problems as other websites (such as LeetCode) - but the problems they do provide are top quality and there is a good range of problem types. Review collected by and hosted on G2.com.

Codility allows me as an aspiring software engineer to take on increasingly complex programming challenges. Coupled with being able to test for scalability and I find myself thinking very critically when it comes to solving these problems. Review collected by and hosted on G2.com.

A lack of resources and peer discussion makes it so that finding a possible solution to a problem is much more difficult. While software engineers should be able to handle working on things independently, you will more often than not work with a team in some capacity in industry, That said, Codility could use a platform for hosting discussions for each programming problem presented.
