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.
ย
Yes! We track current / past collaborators, meaning if you want to check if a potential candidate had access / looked at the solutions you can simply search for them. You can do this by clicking the search icon in the top left at solutions.alexgurr.com and searching for them.

I work on these challenges & solutions in my spare time, on top of a full time job and everything else that comes in life. 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 or submit a new challenge!
