No install required, the repo is a curated link table you read on GitHub.

In plain English

This repository is a curated list of front-end coding challenges that real companies have used as part of their job interviews and that they have published openly on GitHub. The maintainer collects links to these challenges in one place so that people preparing for front-end interviews, or just looking to practice, can try them against the same problems candidates are asked to solve. There is no application here. The repository is essentially a long table. Each row names a company, the country it operates from, the tech stack the challenge expects (such as React, Vue, Angular, or plain HTML, CSS, and JavaScript), a link to the challenge repository where the instructions live, and a link to that company's open jobs on LinkedIn when one is available. Some rows are tagged pt for challenges written in Portuguese and en for ones in English, which reflects the maintainer's Brazilian context and a strong representation of Brazilian companies alongside ones from the US, France, Gibraltar, and elsewhere. The README states the goal plainly: test your knowledge using real job challenges, and only open-source ones. So the value of the project is the index itself. You pick a challenge, follow the link to the company's own repository, and work through their requirements there. The full README is longer than what was shown.
