The scaffolding is done for you. Simply run yarn in any of the directories to start the application. Each application has a README with its requirements.
Some might require connection to external APIs, but all information will be provided in the inididual challenge readmes.
All the coding challenges have been completed to a high standard. Get invited to the solutions repository at solutions.alexgurr.com.
People use these challenges for interviews. By putting the solutions behind a collaboration wall/invite-only repository we can discourage candidates from simply looking up the solutions. We track current/past collaborators, meaning if you want to check if a potential candidate had access/looked at the solutions you can get in touch and find out.
I work on these challenges & solutions in my spare time, on top of a full time job and all the other stuff. Because of this, I don't always get a lot of time to maintain and add new challenges. Interested in becoming a collaborator or submitting your own challenge? Reach out below.
