AI interview module

They will ask how the model works. Not whether you have used ChatGPT.

Generalist McKinsey, BCG, and Bain cases now include an AI layer. One lesson on the basics and the frontier. One original case. Then stop reading and sit the room.

SurePath Mutual

A P&C insurer wants a generative-AI claims copilot — or an agent that can pay. You pick the method, size the error cost, and close.

What this module is

Not a QuantumBlack or BCG X technical loop. Those still exist, and they go deeper. This is the new generalist bar: can you tell a copilot from an agent, RAG from fine-tuning, and a demo score from the cost of a wrong payout — then close like a consultant.

The lesson is deliberately simple. Training vs inference. What “good” means when 98% accuracy is a trap. Prompt, retrieve, fine-tune, or give the model tools. Agents and the harness around them. A little on reasoning models and evals so you do not sound like 2023.

The case is SurePath Mutual, a P&C insurer that wants generative AI on claims. The math is handle cost versus leakage. The judgment is whether you hand the model the payout button.

FAQ

Is this only for QuantumBlack, BCG X, or Bain Vector?

No. Those specialist loops go deeper. This module is the generalist bar: how machine learning actually works, in English, then one case that uses it.

Do I need a technical background?

No. If you can size a value pool and explain RAG vs fine-tuning in one minute, you are in range.

Is the lesson free?

Yes, forever, with or without an account. The scored SurePath interview is open during your free week and included in every plan, same as any other case. Read mode stays free too.

Is CoachNed affiliated with McKinsey, BCG, or Bain?

No. Independent practice. Original prompts. The firms named are for interview-style prep only.
