Hire for agency, not algorithms
Hire engineers who solve
your problems.
We recreate real tickets and PRs from your backlog as interviews — no sensitive data exposed. See every edit, every AI prompt, every decision — not just a score.

INC-3201 — got paged, execution host at 94% disk. runs failing with No space left on device.
/tmp/canary/ has 3000+ dirs from old runs that were never deleted. seems worse on high-volume days.
The technical interview, rebuilt for how engineering actually works.
Problems built from your backlog
Connect GitHub or Jira and we recreate a real ticket or PR as a sandboxed interview problem. Candidates get the full context — no sensitive data, no access to your actual codebase.
A full session replay, not a score
Every edit, every AI prompt, every dead end is recorded. Hiring teams see exactly how a candidate thinks — not just whether they got the right answer.
Measures agency, not memorization
An unfamiliar codebase, a vague ticket, no obvious root cause — the way real work shows up. Canary scores how a candidate navigates ambiguity, uses their tools, and drives to a fix: the agency that actually predicts on-the-job performance.
