A nice place to practice coding
What do you like best about the product?
For a beginner, there are lots of easy exercises to start. Some of them are not complicated and it helps to learn a new programming language. After submitting your own solution, you can see what others did and learn from them and therefore, improve your skills. In the Arcade section, people can comment on the exercise, some of them can be really helpful if you are stuck on the problem, giving tips and tricks on how you can approach the problem without selling out the solution.
What do you dislike about the product?
The challenge section is not the best here. Most of those exercises are reused from other sections and doesn't really gives a big challenge. The ranking for this section is only by character count, this discourages user to write clean code and efficient code.
What problems is the product solving and how is that benefiting you?
I have been solving problems from the arcade section, some of them are easy, good for starting and some of them really makes you think before start to code, which is a nice thing. With the complicated problems, I learned how to optimize my code, reducing execution time.
Recommendations to others considering the product:
There is something for everyone
Awesome Insightful Experience
What do you like best about the product?
It manifested a lot of my weaknesses that I took for granted in both the language and problem solving. I was able to strengthen these and simply by solving the challenges and seeing how other solve the same challenge. Additionally, when you solve a really hard challenge and you have over 50 lines of code and you see the top solution with one line, it definitely gets you digging deep in both problem solving and the language.
What do you dislike about the product?
Sometimes description of the challenges can be unclear or misleading. But getting help from the community with extensive testing usually gets you by these challenges.
What problems is the product solving and how is that benefiting you?
My problem solving skills have definitely strengthened I have learned a pantheon of new features that I utilised. Now my coworkers think am a god. lol
Recommendations to others considering the product:
I find that when you figure out how others get the solutions really improves your ability to be creative in your problem solving.
You should start here
What do you like best about the product?
The user interface for CodeSignal is the best among the programming sites available. The arcade section was addicting and further boosted my motivation to learn a new programming language. If you're into code golfing or enjoy learning how a language work under the hood, the daily challenges provide a fun challenge (even if the difficulty of the challenge itself may not be difficult).
What do you dislike about the product?
The weekly challenges disappeared, challenges recycled, and marathons disappeared. The competitive aspect of the side is decided by the users.
What problems is the product solving and how is that benefiting you?
I solved all types of problems with CodeSignal. The benefits are being able to look at a problem and gain an understanding of what algorithm and data structure to implement for a given task.
One of the best places that you practice your coding skill
What do you like best about the product?
Codesignal has beautiful and friendly user interface. It has many topics and programming languages that you can choose to learn and practice. Especially, codesignal has coding challenge every single day that you can join and solve that challenge.
Codesignal has a good community. They are friendly and willing to help when you have any problems. It also has an amazing profile, you can build your profile and show it in you CV.

What do you dislike about the product?
Many problems and challenges are duplicate. Sometimes, problems and challenges have a bad description and test case.
What problems is the product solving and how is that benefiting you?
Codesignal help me a lot in my studying and my work. It helps me to improve my coding skills and my mindset about solving any problem. It also helps me pass my first interview. Thank a lot.

Better UX than some other competitors but poor quality of daily problems
What do you like best about the product?
The UX is more engaging, and the attempt to gamify interview problems looked fresh at the time they started. However, the quality of daily problems severely declined over the course of the last half a year, so you can't really use them to prepare for real-world programming interviews.
What do you dislike about the product?
Very easy daily problems - the quality as said above declined some time ago, and I feel like some members of the community (myself including) reduced their presence on the site.
What problems is the product solving and how is that benefiting you?
Used it to learn new languages on simple code samples and practice for programming tests.
Really useful
What do you like best about the product?
The daily challenges, you can earn a lot of coins and challenge yourself to write the smallest code possible for a specific problem. Very exciting.
What do you dislike about the product?
The Leaderbords needs better search tools.
What problems is the product solving and how is that benefiting you?
Mainly the arcade sections and the daily challenges. A year ago i had to skip many problems in the arcade first section because i was not being able to solve them. Now i have them all finished and it helps me know if i`m doing good. It`s clear to me that my programming logic has improved a lot.
Recommendations to others considering the product:
It's more fun with friends. That's why i'm trying to convince my university colleagues to use codesignal.
Amazing IDE and interesting problems
What do you like best about the product?
CodeSignal not only provides a fun way to practice and learn new programming skills but also offers different problems with varying difficulties that are sure to challenge most programmers. Moreover, their Interview Practice section is very helpful in preparing and practising for interviews with some of the top companies. Although I work as a researcher in cognitive neuroscience, I find that keeping up to date with current trends and programming languages is an essential skill in most fields.
What do you dislike about the product?
Sometimes it is difficult to understand why some hidden tests are failing to succeed when the issue does not relate to optimization. Another issue that I can mention is that the ratings for solutions in the Challenges are normally based on the number of characters, which leads to unelegant solutions being the top solutions.
What problems is the product solving and how is that benefiting you?
I normally solve problems in the Arcade, Interview Practice, and occasionally in the challenges. By practising regularly I have noticed improvements when it comes to posing different problems in programming terms, and also in optimization and legibility of my code.
Recommendations to others considering the product:
If your company needs an automated tool to test candidates, or if you just want to practice coding on your own, then CodeSignal is one of the best options in the market.
The perfect platform to get better at competitive coding
What do you like best about the product?
I mainly use the Interview mode and Company challenges since I'll be attending campus placements at my university shortly. I have tried other platforms but I couldn't practice consistently on any of them. The reason I feel CodeSignal is better than the rest is because of these features:
1. You know which companies have asked this question which makes it exciting.
2. They specify the time and space complexity to be used in several questions which is what actually helps in the growth of an individual in this domain.
I have participated in tournaments a few times and it might seem overwhelming in the beginning for those who are just getting started in competitive programming but it's good brain exercise.

What do you dislike about the product?
It would be helpful if there was syntax error highlighting. It would be nice if the mobile version is ready since I don't have access to my laptop all the time and like coding on my phone whenever possible.
What problems is the product solving and how is that benefiting you?
In the interview mode since there are a limited number of questions in each topic, it helps me get better in the topics of my choice in a quick fashion.
The company challenges and the time limit have helped me get a better insight into how fast I need to be to solve one question which I had no idea about previously. This is because I've only participated in tournaments which have a collective time limit for a given set of questions.

The best place to improve your coding skills, interview preparation
What do you like best about the product?
Codesignal has really helped me to improve my coding skills, logic, algorithm. It also helps me greatly in assessing my ability and level through tests, challenges and tournament with other coder everywhere in the world.
What do you dislike about the product?
There is nothing that I dislike at codesignal. But it would be better if they could improve the daily challenge features (like before instead of Arcade Daily Challenges) and improve the product in their store.
What problems is the product solving and how is that benefiting you?
I improve my coding skills, logic, algorithm, data types and optimize execution time of the function.
I realized it's the best place to get started with if you're a newbie or started learing a new programming language

Pedagogical approach to reviewing concepts
What do you like best about the product?
The level of difficulty of the questions is just about right
What do you dislike about the product?
The code editor. I wish it didn't make those pesky suggestions in Python after the ":".
What problems is the product solving and how is that benefiting you?
I wanted to review/refresh/assess my skills in Python, JS, SQL, etc to prepare for an interview.
