A Solid Site
What do you like best about the product?
The Daily Challenges. They offer an opportunity to experiment with new functionality and learn new ways to code. The IDE is pretty impressive as well.
What do you dislike about the product?
Sometimes the challenges can be exceptionally basic and more like a quiz than a challenge.
What problems is the product solving and how is that benefiting you?
CodeSignal has helped me refine and optimize some of my code. By seeing the solutions utilized by others, I've been able to find better ways of doing things.
Excellent for Learning and Honing Skills
What do you like best about the product?
I love the arcade mode on this website. It has so many different skills to learn, including dedicated sections for learning Python and MySQL. The interview practice section is very similar. I've found both to be very helpful in refining my skills and seeing where I'm maybe not so sharp.
What do you dislike about the product?
I dislike the code completion questions. A lot of them are very cryptic and hard to follow. There's no documentation to tell you what is going on and some of them are solved in very roundabout ways.
What problems is the product solving and how is that benefiting you?
I used CodeSignal to prepare for the American Computer Science League All Star contest in 2017. I worked a lot on recursion problems and the Python section. Thanks to what I learned on CodeSignal, we actually won the competition. I've found that using CodeSignal gives a very real sense of what my strengths and weaknesses are in programming.
Recommendations to others considering the product:
CodeSignal is great if you're looking to refine a specific skill or learn another programming language. Have patience as you work through the very basic questions at the beginning of the arcade section.
The programmer's taskbook, the community, the game!
What do you like best about the product?
CodeSignal seems to me the best platform to refresh programming skills, learn a new language and refresh algorithmic thinking. Plenty of curious tasks gives a good feed for your brain, - so you're always know what to do in your spare time. Each task has many solutions in different programming languages, so you can compare your solution with real masterpieces by the monsters of programming. Along with constantly available task you can participate in everyday challenges and in tournaments which are held in real time. And - the last but not the least! - you have a constructor to create your own tasks and suggest them to everybody.
What do you dislike about the product?
Different Arcade parts have the same tasks which results in constant de ja vu. The Challenge solutions are ranged by code length in bytes, which is unfair because average program length differs from one programming language to another. Usually everyday tasks are too primitive for skilled programmers - maybe, it would be better to give 2 tasks of different difficulty instead of one.
What problems is the product solving and how is that benefiting you?
The site helped me to remember my student youth with olympiads and challenges when I solved plenty of interesting algorythmic tasks. Some unknown people highly ranked some of my solutions which gave me much pleasure. And I practiced in the Ruby - new programming language for me - whose strength and flexibility helped me to express many thoights with just one line of code.
Recommendations to others considering the product:
Try to solve several first tasks - the best option is Arcade.
Great toy problem platform
What do you like best about the product?
The good and step-by-step nature of the problems, in different technologies, good tests, and instant feedback, beyond the great community that uses the platform. Great for training and preparing for interviews, reviewing Computer Science concepts (especially about algorithms and data structures, which are really important in the context of coding interviews), and training your problem-solving skills. The platform allows you to choose from a wide range of programming languages and also offers a great IDE, which can be configured to resemble the most common text editors used by developers.
What do you dislike about the product?
There are no related resources that teach the technologies for beginners, so if you want to learn something from scratch it is better to find some other resource online that teaches you the fundamentals of programming so that you can train your problem-solving skills after you already have a basic understanding of how a language works. Besides, their social network is not the best, even though it already provides some usefulness for its users.
What problems is the product solving and how is that benefiting you?
Learning new and good languages and keeping myself fresh in my algorithmic skills. I am solving problems usually in the Arcade mode (all of the exercise tracks are interesting and helpful for beginners and advanced programmers alike), but I have also done some on Interview practice. A couple of problems a day should be enough for you to keep practicing solving toy problems and, when needed, the amount of daily exercises can be intensified for when an interview is coming up soon.
Recommendations to others considering the product:
Start at the beginning, doing a few exercises every day and go on to more advanced topics as you gain confidence.
CodeSignals gives you amazing Coding Challenges in a clean looking environment
What do you like best about the product?
It's easy to use, I have everything I need to solve the challenge on one screen, without any scrolling, I have all the languages available, that I want to use, the compiler is working and it gives you an accurate feedback of what was wrong, I can print to the console. I really enjoy the company challenges, since they give you a more practical experience.
What do you dislike about the product?
I don't get any rewards for non-active old challenges and I can't really spend the coins on too many things.
What problems is the product solving and how is that benefiting you?
The problems are really broad. They vary from complex challenges of big companies to minor and easy problems.
Recommendations to others considering the product:
Try to challenge yourself, by using a new language or a language you're not so used to for the easier problems. It will give you great improvements.
Preparing for an interview or just practicing a new language, CodeSignal is the way to go.
What do you like best about the product?
Amazing amount of challenges available which can be used for learning a new code language, maintaining your coding skills or just for fun. I really enjoy being put on the test and CodeSignal does a good job providing those tests.
I also like the new feature where you can do a practice test or certified test as if it was for a real company. It measures how well you do did in 3 categories: Implementation, Problem Solving and Speed. This helps a lot in figuring out what you main focus is to work on in other challenges.

What do you dislike about the product?
With the hard or medium questions you got to make sure to think of all possibilities by yourself cause the test provided do not cut it, although if you earned enough coins from previous challenges you can see the hidden tests. You can create your own tests but it is hard to simulate a huge example for testing the time complexity of your code.
What problems is the product solving and how is that benefiting you?
The interview practice challenges and tests definitely! Also Python in the arcade, cause that was a new language for me. Further the new coding challenges which pop up every day if I am in for some fun!
Recommendations to others considering the product:
Just dig in and solve some challenges, but be patient even if you surprisingly missed some testcases.
There is nothing holding you back to create functions and classes to separate the problem into smaller portions.
You want to look back at your previous submitted code which was actually better? No problem you can.

Fun
What do you like best about the product?
The challenge and seeing other solutions to improve my algorithm
What do you dislike about the product?
Sometimes other problem is very hard to understand, the explaination is very confusing
What problems is the product solving and how is that benefiting you?
Algorithm and sometimes database
Only Pro
What do you like best about the product?
One of the main things, that forced me to register at toptal , was status of "toptaler" . No doubt this is the best platform in the world , and if you work there , you are one of the best developers too.
What do you dislike about the product?
It takes from 1 to 3 month (screening process)
What problems is the product solving and how is that benefiting you?
I' m learning twice faster than usual
Codesignal is for me so far the best way to start coding in a new chosen language.
What do you like best about the product?
The platform is addictive, the challenges stuck in dour brain until you cannot get through them. Some exercises repeat itself, and eventually one remembers the xyntax perfectly by heart.
What do you dislike about the product?
Some basic debugging option would be usefule sometimes
What problems is the product solving and how is that benefiting you?
So far I am at the end of rhe intro Arcade exercises as I just strted python. I want to go through all the python projects.
A Good Mock of Real Interview
What do you like best about the product?
My favorite part about CodeSignal is the technical skill assessment system. I got 60 minutes to complete the 3 algorithm and data structure problems. Because of the strict time limit, I felt I was in a real technical interview. You need to accomplish your nervous seeing the time ticking. That's exactly one of the most important challenges I need to face in a real interview.
What do you dislike about the product?
I would like to get a more comprehend feedback on my assessment, such as what's the gap between my current skills set and a company's hiring bar.
What problems is the product solving and how is that benefiting you?
Assess my technical skills set under a time limit, get feedback on how I perform. CodeSignal provides good feedback, which is the best feedback compared to other systems I could find.
