What Nobody Tells You About Resumes

You think a resume is a document that lists your work history.

You're wrong.

It's a Bid, Not a Biography

It's a bid. A sales pitch.

When you're competing against strangers, your resume is a bid in an auction. You're not just listing qualifications—you're competing. The best bids win.

I look at my resume every year. When I was starting out, annually. Now, every three years—whenever a big project finishes.

You should be able to look at your resume and see what you've actually accomplished. Not what you did—what you achieved.

If you can't add anything new after a year, you were busy but you weren't growing.

But don't make the mistake of working for your resume. That's how you end up with impressive titles and no actual skills. The resume is a mirror, not a map.

The One-Page Rule

I've seen seven-page resumes.

Here's what the hiring manager thinks: "What's the point? What does this person actually do?"

A resume should be one page. Two, max. If you can't fit your value proposition on a single sheet, you don't have a value proposition—you have a list.

The solution is brutal editing.

Think of each job like a PowerPoint slide: big title, small title, bullet points, numbers.

Before and After

Before:

"Through machine learning and deep learning algorithms, constructed and continuously improved power prediction models, improved system performance, applied models to real-time prediction systems, monitored operational status, resolved technical issues, and provided prediction results to wind farms, participated in project analysis, emergency response, report writing and other links."

This is a wall of text. I have no idea what this person actually did.

After:

- Model Optimization: Applied Python to build ML-based power prediction models. Increased accuracy by 23%. - System Monitoring: Deployed real-time prediction system for 12 wind farms. Prevented $340K in losses through early anomaly detection. - Technical Support: Resolved 47 technical issues. Iterated algorithms 8 times based on field feedback. - Reporting: Wrote 14 project reports and emergency response documents.

See the difference?

Even if I only read the bold parts, I know: this person knows ML. They work with real-world systems. They talk to actual humans. They write reports.

That's all I need to know.

Writing Headers That Work

Writing good headers is hard.

I couldn't do this at first. I listed tasks like: "Wrote code" and "Attended meetings."

Useless.

Now I think in terms of impact: "Reduced API response time by 40%" or "Led cross-functional team of 8 people."

Formatting Basics

- Font: At least 16px - Line spacing: At least 1.2 - Bold and color: Use them like highlighters, not paint. Bold the numbers. Bold the results. If everything is bold, nothing is bold.

The Numbers Trap

Numbers matter. But they're a double-edged sword.

"Increased revenue by 23%" beats "Responsible for sales growth."

But here's the trap: some jobs don't have big numbers.

If you worked on one massive project for two years, don't pretend you did twelve small projects. Instead, quantify the sub-components of the big project. "Led UX research for 2.3 million users" sounds better than "Did research."

Build a Master Resume

Make a master resume.

Don't worry about length. Just dump everything—every project, every achievement, every number—into one giant document. Update it whenever something changes.

When it's time to apply, copy the master. Delete everything that doesn't match the job. Tweak what remains.

This matters especially if you've changed careers. You don't want to look unfocused in an interview. Better to edit your resume than to explain your life story while nervous.

The Attachment Question

One page resume, unlimited attachments.

But combine everything into a single PDF. No zip files. One file. That's it.

Think of your resume as a table of contents. The attachments should appear in the same order you mention them. If you list a project, attach proof. If you don't list it, don't attach it.

The Bottom Line

So a good resume has to do one thing: make someone want to meet you. Fast.

A resume is not your entire life story.

It's a strategic document designed to get you a conversation.

That's it.

Everything else is noise.
