  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 1 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by MichaelRochonnn on GitHub. Read the source before you install it.

Installation

Install the Mckinsey Case Interview Strategy AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/MichaelRochonnn/mckinsey-bcg-consulting/tree/main/mckinsey-case-interview-strategy
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/MichaelRochonnn/mckinsey-bcg-consulting.git /tmp/mckinsey-bcg-consulting
mkdir -p .claude/skills
cp -r /tmp/mckinsey-bcg-consulting/mckinsey-case-interview-strategy .claude/skills/mckinsey-case-interview-strategy
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Mckinsey Case Interview Strategy in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Mckinsey Case Interview Strategy on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Mckinsey Case Interview Strategy is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

麦肯锡案例面试应对策略

何时使用

  • 面试官提出商业案例问题(如"某企业利润下滑,分析原因")
  • 面试官提出估算/费米问题(如"美国有多少加油站")
  • 面试官抛出大量信息,需要快速结构化分析

核心原则

面试官的核心目的:观察你如何思考,而非你是否答对。商业问题通常没有唯一标准答案。

应对框架:三步法

第一步:分解问题

  • 将大问题拆解为可处理的小问题
  • 建立清晰的分析框架(MECE原则)
  • 避免试图一次性解决全部问题

第二步:提出关键问题

  • 向面试官询问必要信息
  • 通过提问展示思路方向
  • 确认理解问题的边界和假设

第三步:建立合理假设

  • 在数据缺失时,基于常识和逻辑进行估算
  • 明确说明假设依据
  • 展示数字敏感度

案例类型识别

类型特征应对重点
一般案例麦肯锡真实案例的紧凑版结构化分析框架
开放式案例边界模糊、信息杂乱主动定义问题范围
费米问题稀奇古怪的估算题展示分解逻辑和假设链条

信息流管理

当面试官抛出大量信息时:

  1. 保持冷静,不被信息淹没
  2. 识别关键变量,忽略干扰项
  3. 展示"越挖越深"的探究能力
  4. 适时总结已获信息,确认理解

执行检查清单

  • 是否建立了清晰的分析框架?
  • 是否主动提出了关键问题?
  • 假设是否有逻辑依据?
  • 是否在信息过载时保持了结构化思维?
  • 是否展示了思考过程而非仅给出答案?

常见陷阱

  • 追求唯一正确答案:麦肯锡案例重在过程,结论可合理多样
  • 沉默计算:边思考边出声,让面试官跟上你的思路
  • 跳过假设说明:每个估算数字都要解释来源
  • 被动等待信息:主动索取需要的数据,展示掌控力

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Why use Mckinsey Case Interview Strategy on TypingMind?

Because you install it once and use it with any model. Mckinsey Case Interview Strategy is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Mckinsey Case Interview Strategy in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/MichaelRochonnn/mckinsey-bcg-consulting/tree/main/mckinsey-case-interview-strategy. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Mckinsey Case Interview Strategy?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Mckinsey Case Interview Strategy?

As many as you like. As long as a model supports skills, you can use Mckinsey Case Interview Strategy with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Mckinsey Case Interview Strategy AI skill free?

It is published on GitHub by MichaelRochonnn. Check the repository for licensing terms. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
