Topics offered by Coderbyte and Codewars

Coderbyte and Codewars would help aspiring software engineers ace interviews by hosting practice questions across a wide variety of topics, including:

  • String
  • Trees
  • Arrays
  • Binary search
  • Hash tables
  • Linked lists
  • Prime numbers

Challenges also cover software topics like variables, conditionals, loops, closures, and functional programming. However, Coderbyte hosts starter courses and video solutions to help students learn technical software skills. Codewars relies on their user community to upload challenges, with a focus on practical prep rather than teaching new software skills.

Prices for Coderbyte and Codewars

Although Coderbyte offers 11+ coding challenges and starter course videos for free, most users subscribe for full access. The subscription is $35 per month or $150 billed annually. Users can also make a 1-time payment of $29 for a 14-day plan or pay $79 for a 90-day plan. Paid subscribers get access to 300+ coding challenges, over 1 million user solutions, detailed video solutions from industry experts, mock interview opportunities, and official interview prep materials from top tech companies like Amazon and Facebook.

Codewars hosts community-created online challenges for free. They offer martial arts themed “kata” challenges for beginners and “kumite” coding challenges for more advanced users. As users complete kata challenges, they gain “honors” and improve their ranking. Challenges feature 50+ different programming languages, although some are still in beta phases. After improving their rank, users can create their own challenges for other users to solve and offer feedback. Users can also discuss challenges and ask questions on Codewars’ bustling community forum.

Ratings and reviews of Coderbyte and Codewars

Coderbyte holds a 4.5/5 star rating on G2, where many users praised their detailed challenges and described it as an effective tool for both hiring and interview practice. The program is also listed among the top coding challenges of 2020 on Medium, where users appreciated the mix of officially curated and user-submitted solutions.

However, some users were confused by how long they should spend on challenges, with people noting that they spent anywhere from 5 minutes to 2 hours writing a solution. Although most users felt they benefited from the hands-on practice and detailed solutions, some people felt they could find similar prep content online without paying for a Coderbyte subscription. Although Capterra reviewers praised their in-depth feedback and metrics, some were disappointed that “solutions to all of the problems provided in this platform can be found on Google.” Overall, however, most users were very satisfied with the hundreds of practical challenges and thorough solutions on Coderbyte.

As a free community-based platform, Codewars does not have too many formal product reviews. However, so far their reception has been positive. Hubspot listed their platform among the top 12 best resources to learn code for free. Users on Reddit felt Codewars was helpful for current software developers to practice in their “downtime”, with users appreciating that “it lets me stay sharp on my skills” and “keeps my coding readable.” Although one user still valued the practice, they warned that “the ramp up isn’t too great. You get an easy question, then an insanely hard question.”

A few users were also disappointed that the quality of community-uploaded challenges varies dramatically, warning that sometimes “user-submitted katas are really bad, incomplete, or just plain don’t work.” However, Slant gave Codewars a glowing review, with users impressed that they teach dozens of programming languages, offer “learning gamification” through engaging challenges, and most importantly that they are completely free. Reviewers also liked that “Challenges cover all areas of programming” including algorithms, OOP, functional programming, and more.

Although Codewars is often described as a terrific practice resource for both advanced and beginner software engineers, Quora users warned that “if you aren’t solid on the fundamentals, you will be completely lost on Codewars.” On the whole, users seemed very satisfied with Codewar’s free challenges and active community.
