What evidence would confirm the failure path?
Working softwareAssess candidates in an actual service environment.
Evidence-led evaluationObserve how engineers investigate, change, and verify.
Structured experienceGive every participant clear context and consistent tools.
Our approach
Technical evaluation should resemble the work.
Haeckl provides a guided environment with source code, a terminal, tests, runtime evidence, and an AI coach designed for the assessment context.
Instead of optimizing for memorized answers, teams can focus on how a candidate understands a system, follows evidence, and validates a focused change.
