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.
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.
Code Immersion!
What do you like best about the product?
Seeing others' creative solutions. I am pretty inexperienced at programming so it's really nice to complete a problem and then look at other people's solutions and seeing how it could be done better. It allows me to immerse myself in code, which is the best way for me to improve.
What do you dislike about the product?
People shorthand and teach bad habits. Some of the solutions on CodeSignal seem extremely shorthanded to see how short they can make their code and it teaches some bad habits OR it is very hard to decipher and hard to learn from. The good news is allowing community members to vote on favorite solutions sends other good solutions to the top as well as these.
What problems is the product solving and how is that benefiting you?
I use it to practice a lot of JavaScript (ES6+) and C#. Its a great place to try to practice syntax for different languages. I also like to use the community challenges which oddly enough incentivizes me to look at other languages to see which languages handle certain problems exceptionally well.
Great assessments
What do you like best about the product?
The assessment platform is phenomenal. Generates a very accurate signal for skills especially with new grad candidates. I've also used it with more senior candidates and it can work well there too.
What do you dislike about the product?
Expanding to information security and system design would be a great addition.
What problems is the product solving and how is that benefiting you?
Automatically evaluating technical skills of engineering candidates.
A really fun way to learn and challenge your friends
What do you like best about the product?
The customizable IDE and the good-looking UI makes the coding enjoyable (even addictive) while the big community and variety of tasks allow you to learn new tricks from other developers.
What do you dislike about the product?
Sometimes you could experience some lagging when submitting your code during tournaments and the algorithm that chooses the tasks to solve may be a little predictable.
What problems is the product solving and how is that benefiting you?
My colleagues and I use it 15-30 minutes a day in our spare time to learn from each other and remember the basics of algorithms. Also I would love to use it in coding interviews.
Simple but effective
What do you like best about the product?
I like many aspects of CodeSignal but for me, the best is the arcade.
What do you dislike about the product?
I can't find the T-shirt that they sell with points. Perhaps because they got renamed. I'd like to see more CodeSignal goodies in the future.
What problems is the product solving and how is that benefiting you?
I'm solving easy to medium algorithm problems in the moment. I'm getting better in solving algorithm problems, esp. the easy ones. Also, it helped me improve my python skills.
Great platform
What do you like best about the product?
Codesignal has a great exercising environment for programmers of almost all languages. It’s fun as well!
What do you dislike about the product?
I would look forward to find a 1 vs 1 function to challenge a friend
What problems is the product solving and how is that benefiting you?
It’s great to quickly get familiar with your language again
One of the best platform by which i learned a lot.
What do you like best about the product?
The most helpful thing i found here, is the minimum character count based ranking and that helped me to learn too much about JavaScript.
What do you dislike about the product?
The downside i found is why you guys have disabled the copy paste option there?, i don't know the reason :(.
What problems is the product solving and how is that benefiting you?
I really love to work in this tournaments and daily challenges.
Recommendations to others considering the product:
Add more advanced questions in daily challenges. Some times the questions are seems to be repeating.
Best website to build up a coding habit
What do you like best about the product?
I love the Arcade mode where you can learn and practice coding in your favorite programming language every day and turn it into a habit. I even could get my girlfriend interested in programming.
What do you dislike about the product?
A few exercises at the higher levels of the Arcade mode sometimes have an unclear task description. Also some test cases don't match with the description.
What problems is the product solving and how is that benefiting you?
I have started to write programs in Python for my real job, although the job actually is completely unrelated to coding. The coding skills that I learnt with CodeSignal have really helped me to "automate the boring stuff" and get my work done more quickly. It's a great place to see how other people solve problems and learn from them.
