CodeSignal has become my de-facto platform for practicing algorithms, and it looks like more and more companies are taking to using the platform for applications as well.

Algorithms can be a slog to practice, but CodeSignal offers more features than its competitors that make it actually enjoyable to use. I appreciate the numerous game modes and guided tracks that CodeSignal offers. Combined with the gamified nature - leveling up and earning coins as you go - it's fun to work your way through problems on the platform, and the tracks provide good overviews of important topics to practice. Of course, this would all be meaningless if the problems and coding environment were subpar. Fortunately, CodeSignal offers a good mix of easy to challenging problems. I rarely feel confused as to what a given problem is expecting, and I have never had an issue with the coding environment.

There is not a great aspect of feedback on CodeSignal. After solving a problem, you can view most up-voted solutions submitted by others, but there is no definitive metric for gauging how your submission compares to the optimal solution. CodeSignal could improve through efficiency statistics or explanations for solving problems optimally.

Problems/Exercise range is overpowering .You have a huge repositories . Initially i was not aware of trading your earn point to view solution and understand rationale and methods behind answers and that was a real bonus for me.My over all experience has been extremely good and i find myself spending more and more time at code signal. In fact its became like a habit , when ever i have leisure time i ends up visiting the site and i am sure i will have something new and good here for me.

Purpose of the software is to make you experience competitive environments in IT job markets in a very cooperative and understanding way.You earn points solving exercise- you can use these points to get across if you are struck at somewhere - which means it does not have to be the end for sojourn with this site. Site has some of the best brains in data structure and coding world - you can view their solution and learn a lot from them. Emphasis is not always use run of the mill procedure for solving a problem but prompts you to answer in a better ways , in a more productive way and that is the plus point of the site.

From my limited experience i have with this site i have nothing at the moment.

It is ok if you don't need nothing from codesignal team, if you need any request, your nightmare will start.

Easy to use, thus missing some critical features

Support was ... can't say there's a support.Two year waiting for a vue.js assessment and others, two years waiting to get a few more colors on tags, two years waiting to have the information about who sent the assessment to the candidate, none of those were done.Now we are leaving codesignal, and guess what, there is no way to export any of our tests, those we created manually, even the developer team can do it. This is the support level you will get with codesignal.

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.

I observed that same problems are repeated often in a short span. There are no problems related to image processing.

i am using for three years. it is the best for me

contains a lot of challenges organized by categories, and contains daily challenges, it is amazing web site to practice algorithm challenges

lack some self evaluation tests. but still good
