Challenge
For senior IC roles, the team needed to assess judgment and trade-off thinking — not language trivia or speed.
Approach
Case-style tasks and Deviation Score surfaced how candidates reasoned, verified AI output, and made defensible decisions.
Senior individual contributors are hired for judgment — the ability to make sound trade-offs under ambiguity. Trivia and speed tests measure none of it.
The problem: testing the wrong thing
Fast-typing puzzle rounds couldn't distinguish a senior engineer's reasoning from a junior's memorization.
- Trade-off thinking went unmeasured
- AI made trivia tests even less meaningful
- Promote decisions lacked confidence
The shift: assess reasoning directly
Case-style tasks with Deviation Score revealed how candidates reasoned, verified AI output, and defended decisions.
- Realistic, open-ended problems
- Judgment and verification scored
- Evidence behind every recommendation
The outcome
Offer acceptance hit 91%, promote-decision confidence rose 39%, and time-to-close fell 25% — senior hires chosen on judgment.
