Why We Built ChallengeDojo
Technical interviews are broken. They test memorisation, not capability. ChallengeDojo exists to fix that — for candidates and companies alike.
Most technical assessments measure how well you've rehearsed LeetCode, not how well you can actually build software.
We built ChallengeDojo because we experienced this problem ourselves. Strong engineers were failing interviews not because they couldn't do the job, but because they hadn't memorised enough dynamic programming patterns.
The ChallengeDojo approach
ChallengeDojo presents real-world engineering scenarios — the kind you actually encounter on the job. You're asked to architect a solution, debug a system, or review a pull request, not reverse a linked list in O(1) space.
We track progress over time, build a credentialing system that means something, and give companies a way to evaluate candidates on work that looks like actual work.
What's next
We're expanding the challenge library, building team assessments, and launching a hiring product that connects high-performing candidates directly with companies in our network.
