Backend Challenges is a curated collection of open-source coding challenges sourced from job postings around the world.
The project addresses the need for realistic practice material by aggregating actual backend engineering challenges that companies have used in their hiring processes. Rather than relying on generic algorithmic puzzles, developers can work through problems that reflect real-world job requirements. The collection is maintained as a public repository where contributors can add new challenges they encounter, creating a growing resource of authentic interview and assessment material.
This resource suits developers preparing for backend engineering roles who want to practice with genuine company challenges rather than abstract exercises. It works best for those seeking to understand what actual employers expect and to build a portfolio of solved problems. The project is particularly valuable for developers in different regions, as it aggregates challenges from jobs globally, providing exposure to varied technical expectations and problem styles across different markets.
The project maintains active community engagement through its Discord channel and accepts contributions from developers who encounter challenges in their job searches. Updates to the repository occur regularly as new challenges are added by contributors. The codebase remains accessible and straightforward, reflecting its purpose as a collaborative list rather than a complex application.
