Review

What do you like best about the product?
I like the game-ish design and the achievements, and the online IDE works very well.
What do you dislike about the product?
Having to unlock the higher level difficulty is a pain, as you have to go through a bunch of easier stuff. It'd be nice if I could challenge myself sooner. For example, with Leetcode or Hackerrank, you can do any question you'd like. It would also be nice to have solutions ready and discussions around a particular question. For the coding challenges, we should not have to manually write an expected output, as they can be very long. This can be a problem when we are doing the challenge, as we don't really have the time to write them out, nor do we really now if what we've wrote is a correct expected output.
What problems is the product solving and how is that benefiting you?
I think it really helps people who are new to competitive programming, as the leader board and achievements can help motivate.
Recommendations to others considering the product:
I think it has everything you'd need from this kind of product, but may need to distinguish itself more from competitors. I would mainly recommend this software to people who are new to competitive programming, and want to start from the ground up. It has a fun game-ified take to learning competitive programming, which seems to be what a lot of learning software do nowadays. However, for experienced users, I would not particularly recommend CodeSignal, since it seems like a lot of the challenging questions need to be unlocked first, which can be very tedious.

Good accessible Environment for programing

  • February 09, 2020
  • Review provided by G2

What do you like best about the product?
I used CodeSignal recently for a programing test. I was positively surprised by ease of edit, compile, build, debug cycle. The layout of question, editor and sample data was great accessibility wise.
What do you dislike about the product?
Autocomplete suggestions could be faster.
What problems is the product solving and how is that benefiting you?
Programing questions. It is a good way to screen candiadates.
Recommendations to others considering the product:
Good product to screen candidates.

Responsive interface. Loved the Dark theme.

  • February 09, 2020
  • Review provided by G2

What do you like best about the product?
I personally like the examples at the end. Also, there are no unnecessary information or distraction on the screen which is good. I also liked how the progress is shown on the dashboard.
What do you dislike about the product?
Adding custom test cases is not that intuitive. Adding a custom test case is not fast. I would prefer a text box where I can copy paste my inputs and just run the code. I shouldn't be asked about the output and all. Adding a highlighted line at the place of error in code more likely to be helpful than just showing it
What problems is the product solving and how is that benefiting you?
I used CodeSignal first time for one of my coding interviews and I liked it so much that I created my account and start practicing on this platform. I have not discovered the hidden potential of this platform yet but I hope that I will have more interesting things to discover. Would surely like to review this again after I use it for 3-4 months may be.
Recommendations to others considering the product:
I would suggest to at least give it a try. To me it is the best platform I have used till now. The information about the problems and how it is presented is too good. For instance, I am attempting a problem to solve and if I don't understand the question even after reading it twice the examples at the end makes it clear, not just because it es explained with example but because the way the important things like the return values are highlighted. When running short of time, these highlights things are easy to catch and understand better and quickly which is obviously a huge plus for me.

  • Review provided by G2

What do you like best about the product?
Clear and concise questions and testing. Fast execution and lots of opportunity for valid testing. Nice user interface.
What do you dislike about the product?
User console could be more clear, testing could use more customizability.
What problems is the product solving and how is that benefiting you?
Solved coding challenges. Very clear and easy to use compared to most other platforms.

Technical Interview

  • February 09, 2020
  • Review provided by G2

What do you like best about the product?
Great integration of dev/test approach. The fast feedback loop and hidden tests are a great way to avoid hardcoding.
What do you dislike about the product?
Not being able to see failed hidden tests for learning. This should be visible post completion.
What problems is the product solving and how is that benefiting you?
Just used it for an interview. Not using yet in our company.
Recommendations to others considering the product:
Great tool to assess technical knowledge of employees

Good overall!

  • February 08, 2020
  • Review provided by G2

What do you like best about the product?
The UI was very clean, very easy to see the questions and the sample inputs for each question. It was easy to see how many test cases passed and which ones failed. Very intuitive design! Also, there was very nice autocomplete that you don't see on most online editors. The questions were also very unique and well thought out, I really felt challenged, but there weren't any nasty edge cases or super hairy logic.
What do you dislike about the product?
Not much, the overall experience was excellent, it just felt kinda weird to have my cam & screen shared the whole time, but I guess that's what you have to give to get a thorough candidate check.
What problems is the product solving and how is that benefiting you?
I used it to complete some technical prescreening for a job and also to do some practice for programming. It helps me get interviews for the companies I apply to.
Recommendations to others considering the product:
It's a great platform for programming, the home page is kind of cluttered though.

My review

  • February 08, 2020

What do you like best about the product?
I like the UI of the coding page and how clean it looks.
What do you dislike about the product?
I dislike how it films me and needs to see my webcam.
What problems is the product solving and how is that benefiting you?
I solved a few basic data structures and algorithms problems. Some were very hard and some were very easy.
Recommendations to others considering the product:
Be aware that it will film you.

Gamification + Slick UI = 🎉

  • February 08, 2020
  • Review provided by G2

What do you like best about the product?
I like the gamification aspect the best. It's something that most other websites do not have. It definitely motivates me to use it more than other websites like HackerRank and Leetcode. I also like how solving a problem unlocks the solution leader-board, this encouraged me to try the problems first before looking at the solutions. Using a leader-board for solutions is also something really nice because LeetCode shows a set of solutions but we don't know if those solutions are actually perfectly written (their run-time may be good but it may not idiomatic).
What do you dislike about the product?
There are no explanations for solutions. We can see user-submitted solutions but there are no explanations to them.
What problems is the product solving and how is that benefiting you?
I have been solving simple data structure problems and I realized there are some smart concise solutions to a problem I never realized.
