A review of Coderbyte as a software engineer interview prep tool

Hi, I’m Brian, a former senior software engineer and now software engineering advisor at Pathrise. I work with hundreds of software engineers to help them land their dream job.

What does Coderbyte do?

Coderbyte is an online collection of algorithm and full-stack coding challenges and interview kits, which can be solved in 15+ languages including React, Python, and SQL directly in their online editor. The challenges come with official solutions and tens of thousands of user solutions and discussions. There are also tutorials on topics like advanced JavaScript features, data structures, and algorithm interview questions. Some of their services are offered for free and the rest are part of a paid membership.

Users create a profile where they are rated on the following areas: programming language abilities, data structures, and algorithms. The rating order goes from beginning to expert. Users can move up through the ranks by solving challenges with good scores. The challenge topics correlate with the amount that the user’s ranking increases – for example, solving medium challenges will get your data structures rating up because these challenges require more data structures to be implemented (e.g. binary trees, queues, matrices).

Users can also practice for coding interviews at specific companies that Coderbyte features, like Microsoft and Google, or for generic interviews.

Who is Coderbyte for?

Software engineers who are looking to prepare for technical interviews to get into coding bootcamps like Hack Reactor can use the specific questions to practice for admissions. Those who are looking to prepare for language-based interview questions and technical interview questions can work through specific modules on those topics. Finally, users who are less advanced can take 1-week free classes in Javascript, Ruby, Python, and full-stack development.

How does Coderbyte compare to Pathrise?

Coderbyte is a good tool for software engineers of all skill levels to use in preparation for their technical interviews. The questions are well organized for users to learn new skills or advance their current interests so that they are ready for whatever is thrown at them in technical challenges. 

At Pathrise, we are focused on helping our fellows with the entire job search. Part of that is mastering the technical interview and so we recommend that software engineers in the program practice these types of questions as much as possible so they can go into their interviews with confidence. Sometimes, fellows come back from technical interviews saying that the problem they were assigned was similar to a problem they did in practice, so it is extremely important to utilize online practice platforms. This means there is a good opportunity for people to use Coderbyte and Pathrise together, as Coderbyte can help with technical advancement and Pathrise can help with everything else needed to find the best possible job for a software engineer.


Pathrise is a career accelerator that works with students and young professionals 1-on-1 so they can land their dream job in tech. With our tips and guidance, we’ve seen our fellows interview performance scores double.
