A public list of open-source challenges from companies around the world
A list of real-world frontend hiring challenges from companies, mostly Brazilian but with some international ones. It's a table of links pointing to each company's actual test repo, so you can practice against what they genuinely ask candidates to build. Useful if you're prepping for a job hunt or want to see what React/TypeScript skills companies actually care about.
The challenges are real — these are actual take-home tests from real hiring pipelines, not contrived textbook exercises. The stack column is genuinely useful for filtering: if you're a React/TypeScript person, you can skip the Angular entries without opening anything. Coverage spans entry-level HTML/CSS/JS tasks up to GraphQL/Apollo stacks, so there's a useful range of difficulty. LinkedIn job links next to each company are a nice touch — you can check if they're even hiring before you invest time in their challenge.
Last push was May 2024 and many of the linked challenge repos are years older — a good chunk of those companies have probably changed their hiring process or closed entirely. The list is overwhelmingly Brazilian companies posting in Portuguese, which is a real limiting factor if you're not in that market. There's no difficulty rating or time estimate, so you have no idea if you're signing up for a 2-hour task or a week-long project until you open the repo. Dead links are already appearing (e.g., the Jobsity GitLab link requires authentication) and there's no automated check to flag them.
