Learn a programming in depth
What do you like best about the product?
1) leaderboards score is based on code length so if you want to compete with others you often have to use practices/libraries/hacks that are not commonly used in real life due to readiblity. This is nice way how to sharpen you skills.
2) tournamets. 5 tasks, 10 minutes. Who will be faster? This is good way how to learn to read and analyze problems really fast. Unfortunally not many people join tournaments.
3) arcade mode is pretty cool
4) devops challenges. However they are not produced anymore :(

What do you dislike about the product?
1) I'm not able to comment other solution
2) I liked codefights better. Duels, exp system (warrior, ninja) etc... But I understand you want to be bussiness oriented.
3) repeating or primitive (like return "hello") challenges

What problems is the product solving and how is that benefiting you?
When I joined i was solving only arcade mode. Then I started with challenges and tournaments.
I think my python skills got a lot better and also code reading.

Problem solving never ends here
What do you like best about the product?
I always love to code in a tournament and 10 mins challenges with other users. I could see so much improvements in my presence of mind and problem solving skills. i would recommend this to all my friends as its a good productive diversion from our office work.I'm always having fun at programming with CodeSignal. CodeSignal is full of games of challenges. If one finds time everyday to solve/finish his daily tasks in CodeSignal, he will be mastered in problem solving. Thats all.
What do you dislike about the product?
I observed that same problems are repeated often in a short span. There are no problems related to image processing.
What problems is the product solving and how is that benefiting you?
I always participate in code challenges (10 mins). I feel that my concentration level and presence of my mind improved while I'm taking/solving programming challenges everyday. I used to solve some interview questions when i was looking for a job switch.
Recommendations to others considering the product:
Swear to solve at least two problems twice in a week in CodeSignal if you are going to hunt for a job. Codesignal will groom you with your full engagement in problem solving. Also you can practice interview questions asked in Top companies. You can commit yourself to solve daily challenges posted in Codesignal everyday. You can have fun at programming always. if you are able to allocate some time for CodeSignal everyday, you can finish your tasks assigned to you by it. its like tracking your productivity for your own purpose/confidence.
Intellectual exercises to keep your mind and algorithmic skills sharp!
What do you like best about the product?
Variety of programming modes available: daily challenges, company bots, interview practices, timed tournaments and others
Daily challenges difficulty was recently lowered to make them more likely to be completed in an hour or two, typical of what people spend on these problems on a daily basis
Pick the right questions for your proficiency and you'll feel rewarded afterwards, easy ones will leave you wanting, difficult ones will leave you scratching your noggins for days on end. Problems are typically categorized by coins that they're worth, so they're easy to tease out.
Working on different flavors of algorithm problems will likely challenge in ways that your work (if it's in software industry) likely won't.

What do you dislike about the product?
Text editor is sufficient for general programming, but still lack language specific syntax error checker like a full-bore IDE, which I use for more difficult problems.
Sometimes comment section will have key hints leaked, better curation or comment availability post challenge active period will likely be fairer to early challengers for timed problems.
Challenges are typically ranked in characters length of source, where solution's efficiency might be a better metric for judging implementations.
Server processing time can vary wildly sometimes. I've experienced solutions that passed on second or third tries but failed first due to timeout limit exceeded.

What problems is the product solving and how is that benefiting you?
I have not used CS for job search yet, but it has helped keep my problem solving skills fresh and entertainment through intellectual exercises.
Basic concepts to solving problems can be similar, but feels absolutely fresh when presented in different manners and often requires a degree of "dynamic programming" (pun intended) to trialing different approaches to reach the most efficient solution.

Recommendations to others considering the product:
Try to keep at it on a consistent basis, even when problems trip you up. The more you come back to challenge yourself, the sharper your mind will get, whether it's apparent or not
Best vay to practice your skill
What do you like best about the product?
I start to learn 2d programming language on Codesignal and like an approach when u like a play game level by level increasing difficulty can upgrade not only programming skill, but algorithms although. Additionally mega cool option with interview practice mode.
What do you dislike about the product?
Some of the task in arcade mode could be described more clear (could be founded by negatives votes by users).
What problems is the product solving and how is that benefiting you?
Mostly i focused on solving algorithms and study 2d language on practice.
The overall experience has been good.
What do you like best about the product?
The questions that are provided and the way they are categorized and organized present the user with an opportunity to learn and practice coding more efficiently. Also, the autocomplete and preloaded collections framework helps users focus more on the implementation of the algorithm and on optimizing solution rather than trivial syntax related issues.
What do you dislike about the product?
The fact that top solutions only get disclosed after the solution has been submitted and the use of coins for getting hints is somewhat frustrating. Also, not been able to see your own ranking with a single click doesn't let you estimate your position in the crowd.
What problems is the product solving and how is that benefiting you?
I have solved algorithmic coding problems and it has helped in thinking in a much better way and has prepared me well for facing the interviews.
Recommendations to others considering the product:
It's a good platform to practice coding on. Read the problems carefully and you will be able to solve them. Read other people's solutions and go through discussions even after you have solved the problem because you might still learn something new.
Code Signal for High School CS Class
What do you like best about the product?
I like the bite size approach to the challenges, and how they enhance the problem solving approach that I have for the class. I encourage students to take on the challenge and many do.
I like that you can redo the challenges with a different language.
I also like the variety of the challenges.

I also like the variety of the challenges.
What do you dislike about the product?
It is very addictive and sometimes students are distracted from their work in different classes. It is very easy to get into the mode of thinking that I will just look at the next challenge and wind up working the problem.
There is not much to dislike here, I have noticed that some of the challenges are difficult and then the very next one is super simple.

What problems is the product solving and how is that benefiting you?
I'm working on the Arcade with Python 3 and it has really help me learn some important features of the language with lists, strings, dictionaries, etc.
It is also a good source of additional practice for my students.

I would definitely try it.
Well-organized questions with a convenient and pretty UI
What do you like best about the product?
First of all, I was impressed with how well the questions are organized on the site. I will be honest that on many competing sites the organization is trouble. This means that such a system only works when you know what you need from a resource. In this case, CodeSignal helps you.
Secondly, the pretty UI makes it a pleasure to work with the website. Great pictures and stories behind the tasks make usage of the CodeSignal fascinating.
Last but not least, CodeSignal has a very smooth transition in difficulties of the tasks. It helps a user not being overwhelming from something challenging from the beginning.

What do you dislike about the product?
Up to this point, I have not met the "common" questions on the site like Reverse a Linked list. The CodeSignal tasks are more real-life and close to the questions on real technical interviews. Here is a question: is it a good practice or wrong? Does it mean that people who can solve such problems will take "common" questions very quick?
What problems is the product solving and how is that benefiting you?
Preparing for a technical interview and raising the overall skill level. The CodeSignal helped me understood that the organization of the questions is very important!
No better way to practice and consolidate your coding knowledge
What do you like best about the product?
The holistic approach that CodeSignal offers: challenges, tounaments, learning curriculum, etc. You don't have to leave CodeSignal to have a complete learning experience.
What do you dislike about the product?
CodeSignal doesn't work on a phone, otherwise - everything is perfect.
What problems is the product solving and how is that benefiting you?
I'am doing tournaments to improve my problem solving speed, coding challenges to improve my algorithmic thinking and arcade to learn the fundamentals.
Fun and Insightful
What do you like best about the product?
The things that I like the most about this websites are:
1. The UI is super intuitive
2. The Content are well designed, especially if you're preparing for an interview
3. The badges somehow motivate me to solve more problems
4. There are always ongoing competition that you can be participating in
