餐巾紙公式

Past Interviews = Snapshot of Productive Capacity (Coding skills) AI Era Interviews = Derivative of Judgment (Learning speed + Vector of growth)

一句話

Since AI has commoditized raw coding, engineering interviews must shift from measuring a candidate’s current productive capacity (the snapshot) to measuring their judgment, articulation, and rate of learning (the derivative).

  [ The Judgment Loop ]
  Decide -> Act -> Evaluate Result -> Articulate Learning -> Make Next Decision Better
  
  [ Evaluation Shift ]
  Traditional: Current Skills (Principal / Weights)
  AI Era     : Learning Speed (Interest Rate / Algorithm)

ROUND 1: SKELETON | 骨架掃描

• AI broke traditional interviews: code production is no longer scarce, and skills expire rapidly.
• What to measure: Judgment (Strategic Thinking, Design Ability, Evaluation, Articulation, Initiative).
• The Judgment Loop: Decide -> Act -> Evaluate -> Articulate -> Improve.
• Articulation is highly prized because it scales judgment to both humans and AI agents.
• How to measure: Evaluate the derivative (trajectory) rather than the snapshot (current point in time).
• Analogies: Track record is principal, learning speed is interest rate. Track record is ML model weights, learning speed is the ML algorithm.
• Method: Ask questions that require connecting a past point to the present to expose the vector of growth.
• Live interviews require AI use to see how candidates instruct, verify, adapt, and articulate mid-task.
• Level differences: Juniors (pure interest rate), Seniors (choosing direction & lifting org rate), Managers (designing org compounding).

ROUND 2: DISSECTION | 血肉解剖

• The scarcity shifted from writing code to deciding what to build and what to discard.
• Strategic thinking: Writing the objective function because AI only optimizes what it’s told.
• Design Ability: Since implementation is free, the value lies in designs that are easy to change/discard, or deciding not to build.
• Articulation: The ability to abstract experience into words. This multiplies impact because it scales to other humans (mentoring) and AI (prompting).
• Evaluating the Derivative: Instead of asking “What are your strengths?”, ask “Which of your skills will be worth less in 2 years and what will replace them?”
• Live AI exercises: Require candidates to use AI. Observe their first instruction, reaction to output, pivoting from dead ends, handling new constraints, and articulation of the experience.

ROUND 3: SOUL | 靈魂提取

The true value of a professional in an era of infinite cheap production is their algorithm for adaptation. By evaluating the derivative (the rate of change) rather than the snapshot (the current state), we assess their capacity to navigate a reality where the foundational technologies rewrite themselves every few months.

DEEP READ | 精讀指引

• “Writing programs is becoming something you can simply hand to AI. Take-home assignments can be solved by AI. It makes no sense to use AI in day-to-day work and then require handwritten coding only in the interview.”
• “If human work is moving from making things to choosing among them, then the eye that can tell good from bad is itself the skill.”
• “Hiring in the age of AI has shifted from addition of headcount to multiplication of amplification.”
• The ML analogy: “Evaluate the learning algorithm, not the current weights. That is derivative evaluation.”
• Example rewrite: “Tell me about your accomplishments” → “How did your criteria for judgment change before and after that experience?”
