🚨 BREAKING: Claude can now build your entire resume and LinkedIn profile like a $500/hour executive recruiter from Robert Half. For free.

Here are 11 prompts that get you interview calls within 7 days:

(Save this before it disappears) Image 1. The Google Recruiter 6-Second Resume Rewriter

"You are a senior technical recruiter at Google who has screened 100,000+ resumes and decides within 6 seconds whether a candidate moves forward or gets rejected — because that's all the time your resume gets before the next one loads.

I need my entire resume rewritten to survive those brutal 6 seconds.

Rewrite:

- Professional summary: a 2-3 sentence power statement that instantly communicates who I am, what I do, and why I'm exceptional
- Every bullet point transformed: rewrite using Google's XYZ formula — 'Accomplished [X] as measured by [Y] by doing [Z]'
- Numbers on everything: add specific metrics, percentages, dollar amounts, and scale to every single achievement
- Weak verb elimination: replace 'helped,' 'assisted,' 'worked on,' 'was responsible for' with power verbs — 'architected,' 'drove,' 'launched,' 'reduced,' 'scaled'
- - One-page enforcement: ruthlessly cut filler, outdated skills, and irrelevant jobs (two pages only if 10+ years experience)
- Skills section overhaul: organize into categories (Technical, Tools, Frameworks, Certifications) matching my target role
- Education formatting: degree, school, honors only — remove GPA if below 3.5 or more than 3 years post-graduation
- Red flag removal: eliminate employment gaps in formatting, outdated technologies, and anything that wastes recruiter attention
- Visual hierarchy: name largest, then section headers, then body text — the eye must flow effortlessly top to bottom
- Before/after comparison: show me the weakest 3 bullets from my original resume alongside the rewritten versions

Format as a complete, ready-to-submit resume with every section rewritten plus a tracked-changes summary showing what was improved.

My current resume: [PASTE YOUR ENTIRE CURRENT RESUME AND THE JOB DESCRIPTION YOU'RE TARGETING]"

🚨BREAKING: AI can now teach business strategy like Harvard MBA professors (for free).

Here are 12 insane Claude prompts that replace $150,000 MBA degrees (Save for later) Image 1. The Harvard Business School Case Study Analyzer

"You are a professor at Harvard Business School who teaches the legendary case study method — the same approach that trained the CEOs of JPMorgan, Goldman Sachs, Nike, and Bloomberg to think through complex business problems systematically.

I need you to teach me any business concept by walking me through a real company case study the way Harvard professors do in class.

Teach:

- Company background: the real company, its industry, and the strategic situation it faced
- The central dilemma: the specific decision the CEO had to make with no obvious right answer
- Stakeholder map: who was affected by this decision and what each stakeholder wanted
- Data analysis: the key financial and market data that informed the decision
- Option generation: the 3-4 realistic paths the company could have taken with pros and cons for each
- Framework application: which MBA framework (Porter's Five Forces, SWOT, BCG Matrix) applies and how to use it
- What actually happened: the decision the company made and the real-world outcome
- Lessons extracted: the 3 timeless principles I can apply to my own business or career
- Cold call simulation: ask me 3 tough questions about the case as if I'm a student in your HBS classroom
- Recommended reading: 2-3 additional cases or books that deepen my understanding of this concept

Format as a Harvard Business School-style case discussion with the Socratic questioning method that forces me to think, not just read.

The topic I want to learn: [ENTER ANY BUSINESS CONCEPT — COMPETITIVE STRATEGY, PRICING, LEADERSHIP, INNOVATION, NEGOTIATION, ETC.]"

When you think of "quiet luxury," you're thinking of The Row.

They never advertise. They barely do press. But they're your favorite fashionista's favorite label.

This is the story of two mogul designers who silenced critics and created one of the most coveted brands on earth: 🧵Image If you didn't know Mary-Kate & Ashley Olsen started The Row, you're not alone. Their anonymity is by design.

Once a side project, The Row is a case study in building a luxury brand—and setting trends by being anti-trend.

And 17 years ago, it all started with one white T-shirt. Image
