Evidence-based developer evaluation

See how developers actually build.

Run realistic software challenges, capture evidence from the work, and review technical evaluations you can inspect.

Real product example

Same challenge. Different evidence. Different outcome.

Alex left a meaningful development trail and submitted a solution. Jamie did not leave enough candidate-attributable evidence. DevMarathon reflects that difference instead of forcing both runs into a score.

Follow the evidence

The final code is only part of the story.

See the work behind the submission, then inspect the evidence behind the evaluation.

01 / Activity

See the work behind the submission.

Recorded development activity gives reviewers context beyond the final result.

02 / Evaluation

A score should show its work.

Technical Evaluation surfaces criterion judgments, confidence, and evidence references so reviewers can inspect the basis of the result.

Evidence first

No evidence. No invented certainty.

When candidate-attributable evidence is insufficient, DevMarathon can return no overall score instead of pretending the signal is stronger than it is.

AI supports the review. Your team makes the decision.

Human review remains final.

For developers

Turn an idea into a finished build.

DevMarathon generates a plan and starter structure, then gives you milestones and a workspace to carry the project through to a completed result you can share.

FAQ

Questions before you start?

Is DevMarathon another coding quiz platform?

No. Hiring challenges are built around repository-backed development work and the evidence captured from that process.

Does AI make the hiring decision?

No. Technical Evaluation supports the review. Human reviewers make the final decision.

What happens when there isn't enough evidence?

DevMarathon can return insufficient evidence instead of producing an unsupported overall score.

Does DevMarathon review the entire repository?

Technical Evaluation uses controlled evidence selected from the submitted work. It does not independently browse the candidate's repository.

Is the hiring workflow a subscription?

No. Challenges, candidate participation, evidence, and manual review are free. Additional AI Technical Evaluations are one-time purchases.

Can developers use DevMarathon on their own?

Yes. Solo Marathons provide an AI-generated plan and starter structure, milestones, a workspace, and a completed result you can share.
