Every TryCrucible candidate has completed a real AI challenge — RAG, agents, MCP, evals — scored by AI and reviewed by domain experts. Filter by skill and score. Read the code before the first call.
Verified skills, not claimed ones
Every candidate has completed at least one hands-on challenge evaluated by AI and a human expert. The score is attached to real, runnable code you can inspect before the first call.
Cut screening time by 80%
Filter by challenge category and minimum score. You reach out only to candidates who have already proved they can do the job — no resume screening required.
Read the code, not the CV
Each profile links to the submission repo. Read the decisions doc, browse the code, check the AI score breakdown — all before a first conversation.
Create a company account. You get 10 candidate searches and 3 challenge credits immediately — no card required.
Filter by AI skill category and minimum score. Browse verified profiles in seconds.
Read submission repos, score breakdowns, and AI evaluation notes before reaching out.
No middlemen, no recruiter fees. Reach out to candidates via their public profile.
Several overlapping signals make proxy work detectable — and expensive enough to deter.
Temporal minimums
Every challenge has a minimum completion time based on difficulty. Submissions that arrive suspiciously fast are automatically flagged.
GitHub provenance checks
The submission repo is cloned and inspected. Repo age, commit count, author email, and commit timestamps are all checked before evaluation begins.
Decisions doc authenticity
Every submission requires a decisions.md explaining key engineering choices. Our AI flags vague or generic explanations for human review.
Cross-submission similarity
Submissions are embedded and compared using vector similarity. Near-identical submissions across different candidates are caught automatically.
Human review for high scores
Any submission scoring 88 or above is routed to a human expert reviewer before the score is finalised. A proxy's work rarely survives this.
Scoped LLM keys, no internet
Candidates work with a temporary LLM key scoped only to their challenge. The sandbox has no internet access — no Stack Overflow, no external APIs.
