A nice break from the bigger problems
What do you like best about the product?
- Switching between different programming languages in order to accomplish a task (altough Python3 seems to be my favorite)
- Small challenges that keep you occupied for a few minutes to half an hour so that I can just get a little break when I'm actually working on something else
- Daily challenges. It's so nice to see solutions of other participants and learn from their approaches. I even got some upvotes, which boost my ego ;)

What do you dislike about the product?
The editor. Code completition has been a nightmare, so I turned it of. Sometimes it tried to complete something I just didn't want.
Apart from that there's not really much to complain about.

What problems is the product solving and how is that benefiting you?
I'm basically trying to solve all the problems that the platform provides. The tasks that need efficient solutions are the most challenging ones for me, as I sometimes don't pass the hidden tests due to an unefficient approach. So I'm forced to be more efficient; a huge benefit for me.
Best site for practice!
What do you like best about the product?
There are plenty of problems to solve, in a wide variety of topics, different modalities if you get bored of an specific topic you can always try company challengues, arcade or daily challebgues.
What do you dislike about the product?
They should have some kind of filter for the tasks and challengues submmited, some are easier and some other require a specific knowledge, I've seen same problems being used in arcade and daily challengues, I would like to the a filter in the solutions in arcade by chars submitted
What problems is the product solving and how is that benefiting you?
There are plenty of good programmers, which means there are plenty of smart solutions, you can see what other users did and learn from that!
Excellent source of programming challenges.
What do you like best about the product?
Variety of coding problems for students of all levels and abilities. Code golfing can illuminate language features. Problems involving graph algorithms and advanced data structures like tries.
What do you dislike about the product?
Sometimes the daily challenges are recycled, and sometimes they are pitched so low as to be useless (e.g., write a function that takes two integers and returns the sum).
What problems is the product solving and how is that benefiting you?
I solve the Arcade problems and the daily challenges, and I recommend all of my students to use CodeSignal consistently in order to sharpen their coding skills and to build recognized credentials.
Recommendations to others considering the product:
There are challenges for programmers of all levels of skill and experience, so jump in and participate on a daily basis.
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
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.

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.

Recommendations to others considering the product:
I would definitely try it.
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.
Addictive
What do you like best about the product?
Tons of problems to solve.
Company problems
Interview practices
Tournaments
Community problems to use and solve.

What do you dislike about the product?
The page is not responive and content can not be read from a mobile device.
What problems is the product solving and how is that benefiting you?
Interview practice - I've noted a big improvement in my coding skills.
Tournaments - I have fun and improve my speed, which is good because I usually take too much time to analize things.

In the world of copy paste finaly somewhere when I code

From my perspective this is a brain-muscle training. It also helped me when I started to learn GoLang. Codesignal is great as an education support tool.
What do you dislike about the product?
Level of daily challenges unfortunately has recently fallen but there is still a lot of hard tasks to accomplish
What problems is the product solving and how is that benefiting you?
After few months of playing with simple tasks the interview challenges are something that I appreciate. So no mater what level you are, you will always find something for you
