Case Interview Coach — a Claude Skill

A Claude Skill that turns Claude into a demanding personal case-interview coach for consulting and product-strategy interviews (BCG, BCG X, McKinsey, Bain, PM/strategy rounds).

Built after prepping for a BCG X interview in one week — the whole system, packaged so anyone can reuse it.

What it does

• Scopes prep to growth, profitability, and product-strategy cases
• Runs a cold diagnostic to map your weaknesses, then targets them
• Builds interviewer personas from a real interviewer's public background
• Rotates pressure: quick-fire, stress tests, and full deep-dive cases
• Scores every case on a 6-dimension rubric with an honest revision list
• Drops the validation and gives sharp, unsparing critique

How to use it

Claude Code

# personal skill (available across projects)
mkdir -p ~/.claude/skills/case-interview-coach
cp SKILL.md ~/.claude/skills/case-interview-coach/

Then just tell Claude you want to prep for a case interview — the skill activates on its own.
