A review of CodeChef as a software engineering interview prep tool – 2023

What does CodeChef do?

Hosting thousands of challenges and user solutions, CodeChef is an online community and platform where software engineers can complete practice problems to prepare for technical interviews. Ranging in level from beginner to advanced, the challenges test users’ skills in algorithms, binary search, array size, and more. In fact, each problem is tagged by difficulty level and topic. So, users can easily find problems that address specific skills and concepts. 

CodeChef has an in-browser coding window where users upload, write, and run code. Users can submit solutions in over 35 languages. They earn points for correct answers, which allows them to move up through the CodeChef ranks. After they submit, a judge evaluates their solution, highlighting any errors or discrepancies in the code. Then, once users feel ready, they can challenge their peers and participate in contests. In addition to accessing their peers’ solutions, users can ask questions and offer advice on the discussion forum.


Who is CodeChef for?

Intermediate and advanced software engineers who are looking to advance their skills and learn new techniques to prepare for technical interviews could benefit from using CodeChef’s exercises. However, uers should have a strong background in databases, algorithms, and arrays. 

What does CodeChef cost? How much work is involved?

CodeChef is free. To register, users can create a profile with their GitHub, Facebook, Google, or email accounts. 

Ratings and reviews

In general, advanced software engineers praised the rigor of CodeChef’s challenges and the thoroughness of the user solutions, though they emphasize that the problems are not for beginners. For instance, one Reddit reviewer recommends CodeChef for competitive coding. But, they suggest that you “start with HankerRank and then slowly after some time start doing long challenges on CodeChef.” 

A reviewer on Quora advised that “you should be efficient enough to implement moderate level data structures like BST, graphs, stacks and heaps using lists” before using CodeChef. Highlighting the importance of having advanced knowledge before doing problems on CodeChef, a beginner on Reddit reported that he “was stumped” by “the most submitted questions in the easy section.”
