What does Coderbyte do?

Coderbyte is an online collection of 300+ algorithm and full-stack coding challenges and interview kits. Users can use 15+ languages including React, Python, and SQL and solve the problems directly in their online editor. The challenges come with official solutions as well as over 1 million user solutions and discussions. Users can filter challenges by difficulty, topic, and/or company. They have interview questions from Google, Facebook, Amazon, and Microsoft.

Newer developers can check out the 1 week long starter courses, which teach the fundamentals of algorithms, JavaScript, Python, and Ruby in one week (each).

In order to access the material on Coderbyte, users first create a profile. They take an assessment to be rated on their skills in programming language abilities, data structures, and algorithms. Users can move through the ranks by solving challenges correctly.

Users can also practice for coding interviews using Coderbyte interview kits. They have interview kits for data structures & algorithm, Ruby, and Google. These kits provide questions on a variety of topics and skill levels. Users can also participate in a mock interview through the platform.

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. 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 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.

If you want to work with any of our mentors 1-on-1 to get help with your software engineer interviews or with any other aspect of the job search, become a Pathrise fellow.
