A Proof is the assessment template at the centre of every Concert. It defines how many stages competing candidates work through, what they must deliver at each stage, and how much they are compensated.

44A human-readable label for the Proof, typically mirroring the job function or related skills.
A private memo for your hiring team — describe the intent of the assessment, any quirks in the brief, or context that helps reviewers interpret deliverables consistently. Candidates never see this field.
The fixed fee in USD paid to every candidate who submits a deliverable for this stage, regardless of quality or hiring outcome. The platform minimum is $40 per estimated hour. Pudding processes compensation immediately upon delivery, and the candidate receives 100% of the payment promised.
The expected delivery medium. Pudding uses this to collect candidate submissions and share replicas with hiring teams. Supported formats are github, google_docs, google_slides, figma, dropbox, and notion. Support for gemini, claude, and chatgpt is in development.
The brief given to candidates verbatim. This is the most important field in a Proof. Before a Concert can launch, Pudding's AI reviewer scans every stage's guidelines across six criteria:
Suspicious content — malicious, deceptive, or illegal material.
Misclassification risk — mandating specific working hours, referencing internal systems, requiring employer-owned tooling, or setting hard deadlines.
Unreasonable pay — compensation that works out below the platform minimum hourly rate based on the expected effort.
Invalid exchange — directing candidates to submit deliverables to an outside contact or system, or to make contact with anyone.
Inactionable briefs — guidelines a reasonable professional could not interpret or act on.
PII requests — asking candidates for a résumé, photograph, social media profiles, or other personal details.
When true, candidates are presented with a non-disclosure agreement before accessing the guidelines for that stage. Use this only when the the nature of the stage is sensitive.
