What it is
This is a curated, public list of front-end coding tests that companies have shared publicly, mostly from job applications. Each row names a company, the tech stack the test uses (such as React, HTML, CSS and JavaScript), and a link to the challenge's code repository. It is meant for anyone who wants to practice real-world front-end skills or see what hiring tests look like.
- Pick a challenge from the table and attempt it to practice a specific stack
- Browse the Stack column to see which technologies a given company tests
- Use linked challenge repos as small projects to build a portfolio
Great for
- Front-end developers preparing for job interviews
- Students wanting realistic practice projects
- Developers comparing skills expected across different companies
- Anyone looking for a sample of common front-end stacks like React or Redux
Not ideal for
- People wanting a runnable software tool, since this is a list of links, not an application
- Anyone expecting official answers or solutions, because the README only links to the challenge repositories
- Readers needing guidance in English only, since many entries are in Portuguese (the README marks language per row)
How to get it
- 1
Read it online
Clone the repository locally

- Read that repository's own instructions to set up and attempt the challenge
- 3
Get the most out of it
- Filter mentally by language column (pt or en) to find the version you can read
- Look for stacks you want to learn, such as React or Redux, and start there
- Check the Jobs on LinkedIn column to see whether the company is hiring
Downloads
Strengths
- Based on real hiring tests rather than invented exercises
- Organized by company, language and stack in a single table
- Released under the MIT license
Trade-offs
- It is a list of external links, so some linked repositories may change or disappear over time
- The README as shown does not explain how entries are verified or maintained
- Some table rows appear incomplete or inconsistently formatted
