Resume Tips That Actually Get You Interviews

I've reviewed 10,000+ engineering resumes. Here's what separates the ones that get interviews from the ones that get ignored—and it's not what most career coaches tell you.

By SIA13 min readJanuary 2025

Your resume has one job: get you an interview. That's it. Not to tell your life story. Not to showcase every technology you've touched. Not to explain your career philosophy.

Most engineering resumes fail at this one job. They're packed with irrelevant details, written in passive language, and optimized for nobody. Then candidates wonder why they're applying to 200 positions and getting 2 interviews.

Let me show you what actually works.

The 6-Second Rule

Here's the reality: I spent 6-10 seconds on your resume during the initial screen. Sometimes less. I'm scanning for signals—evidence that you can do the job. If I don't see those signals immediately, you're in the "no" pile.

This isn't because recruiters are lazy. It's because we're screening 300 resumes for 5 interview slots. Speed is survival.

Your resume needs to be scannable. The most important information—your impact, your skills, your trajectory—needs to jump off the page in those first 6 seconds.

The Anatomy of a Great Tech Resume

Let's break down each section and what actually matters:

1. Header: The Basics

Keep it simple. Name, location (city/state), email, phone, LinkedIn, GitHub (if you have meaningful repos).

Bad Header

John Smith
Passionate Full-Stack Developer
Objective: Seeking challenging role...
123 Main St, Apt 4B, City, ST 12345
john.smith.developer.2025@gmail.com

Good Header

John Smith
San Francisco, CA
john@smith.io | 555-0123
linkedin.com/in/johnsmith
github.com/jsmith

Don't include: Objective statements (waste of space), full address (privacy + useless), headshot (this isn't LinkedIn), age, marital status, or quirky email addresses.

2. Experience: Show Impact, Not Duties

This is where most resumes die. Engineers list what they were "responsible for" instead of what they actually accomplished.

The Formula That Works:

[Action Verb] + [What You Did] + [How You Did It] + [Measurable Result]

Weak Bullets

  • Responsible for backend services
  • Worked on improving site performance
  • Collaborated with team on features
  • Used React, Node.js, and PostgreSQL

Strong Bullets

  • Built microservices architecture serving 10M+ requests/day with 99.99% uptime
  • Reduced page load time by 60% through code splitting and lazy loading, increasing conversion 8%
  • Led team of 4 engineers to ship checkout redesign 2 weeks ahead of schedule
  • Architected real-time notification system using WebSockets, Redis, and React, handling 50K concurrent users

See the difference? Specific, quantified, focused on outcomes. Every bullet should answer: "So what? Why does this matter?"

3. Skills: Strategic, Not Comprehensive

Your skills section shouldn't be a laundry list of every technology you've touched. It should be strategic—highlighting what's relevant for the role you want.

Good Skills Section Structure:

Languages: JavaScript, TypeScript, Python, Go

Frontend: React, Next.js, Vue, Tailwind CSS

Backend: Node.js, Express, Django, PostgreSQL, Redis

Tools: Docker, Kubernetes, AWS, Git, Jest

Pro tip: Put your strongest, most relevant skills first in each category. Recruiters scan left to right. If the job requires React and you list it fifth after jQuery and Angular 1.x, you're signaling the wrong thing.

4. Education: Keep It Short

Unless you're a new grad, education is a footnote. List your degree, school, and graduation year. That's it.

Bachelor of Science in Computer Science

Stanford University, 2019

Don't include: GPA (unless it's 3.8+ and you're a new grad), coursework (nobody cares about Data Structures 101), high school (seriously, stop), or "some college" if you didn't finish (just omit it).

The ATS Reality Check

Before a human sees your resume, it goes through an Applicant Tracking System (ATS). If the ATS can't parse your resume or doesn't find the right keywords, you're automatically rejected. Here's how to pass:

ATS-Friendly Checklist:

  • Use standard section headers: Experience, Education, Skills. Not "My Journey" or "Technical Arsenal."
  • Avoid tables, text boxes, and columns: ATS can't parse them correctly.
  • No headers/footers: Information there gets lost or misplaced.
  • Use standard fonts: Arial, Calibri, Times New Roman. Not Papyrus.
  • Include keywords from job description: But naturally, not keyword-stuffed.
  • Save as .docx or .pdf: Check which format the ATS prefers (usually .docx is safer).

Test your resume: Copy/paste it into a plain text file. If the formatting breaks horribly, the ATS will struggle too. Simplify.

Tailoring: The Unlocked Cheat Code

Here's the secret most people ignore: you should never send the same resume to different jobs.

I know, it's more work. But the response rate difference is staggering. A tailored resume gets 3-5x more interviews than a generic one.

How to Tailor Effectively (15 Minutes Per Application)

  1. Read the job description carefully. Identify the must-have skills and requirements.
  2. Adjust your skills section. Reorder to prioritize their tech stack. If they want AWS and you buried it, move it up.
  3. Rewrite 2-3 bullet points. Emphasize experience that's most relevant to this role. Use their language.
  4. Mirror keywords naturally. If they say "microservices architecture," use that phrase instead of "distributed systems."
  5. Update your summary (if you have one). Make it specific to this role and company.

This isn't lying or embellishing—it's highlighting the most relevant parts of your true experience for each opportunity.

The Numbers Game: Quantify Everything

Recruiters and hiring managers love numbers. They're concrete, scannable, and impressive. But most engineers struggle to quantify their work. Here's how:

What to Quantify:

  • Scale: Users, requests/day, data volume, traffic
  • Performance: Latency reduction, uptime, speed improvements
  • Business impact: Revenue, conversion, retention, cost savings
  • Team impact: Number of people mentored, led, collaborated with
  • Efficiency: Time saved, reduced incidents, faster deployment

Can't find exact numbers? Estimate conservatively. "Served ~1M users" is better than "Served many users." Just don't lie—you'll get caught in the interview.

Common Resume Killers

Instant Rejections:

  • Typos and grammar errors: Signals lack of attention to detail. Proofread 3 times. Use Grammarly. Have a friend review.
  • Inconsistent formatting: Different fonts, sizes, or styles. Pick a format and stick to it ruthlessly.
  • Buzzword overload: "Synergized cross-functional stakeholders to leverage cloud-native paradigms." Just... no.
  • Irrelevant information: Your barista job from 2010 doesn't belong on your senior engineer resume.
  • Lying or exaggerating: We can tell. And we'll verify. And then you're blacklisted.
  • Too long: If you have 3 years of experience and a 3-page resume, you don't know how to prioritize.

The GitHub/Portfolio Question

Should you include a GitHub link? Only if your repos are impressive and actively maintained. A GitHub full of abandoned tutorials and forked repos with zero commits hurts more than it helps.

Good reasons to include GitHub:

  • You have well-documented, original projects
  • You contribute to major open-source projects
  • Your code demonstrates skills you're claiming on your resume
  • You're a new grad trying to show practical experience

Skip it if: Your repos are mostly forks, class assignments, or haven't been touched in 2 years. Better to leave it out than to give us a reason to question your skills.

The One-Page vs Two-Page Debate

Here's the real answer:

  • 0-5 years experience: One page, no exceptions
  • 5-10 years experience: One page preferred, two if you have genuinely impressive accomplishments that don't fit
  • 10+ years experience: Two pages max

The constraint forces you to be selective. If you can't prioritize what matters most, how will you prioritize on the job?

Action Verbs That Actually Work

Start every bullet with a strong action verb. But avoid overused, weak ones like "helped," "participated," or "was involved in."

Strong Action Verbs for Engineers:

Building

Architected, Designed, Built, Developed, Engineered, Implemented

Improving

Optimized, Reduced, Increased, Improved, Accelerated, Streamlined

Leading

Led, Drove, Spearheaded, Mentored, Collaborated, Coordinated

Your Resume Checklist

Before sending your resume, verify every item on this list:

  • Every bullet point shows impact, not just responsibilities
  • Numbers and metrics wherever possible
  • Tailored to the specific job and company
  • ATS-friendly format (no tables, columns, graphics)
  • Zero typos or grammar errors (triple-checked)
  • Consistent formatting throughout
  • Most relevant skills listed first
  • Contact info is current and professional
  • File named properly (FirstName_LastName_Resume.pdf)

The Truth About Resume Success

Your resume won't get you the job. It gets you the interview. That's the only goal. Don't try to tell your entire story—just give them enough to want to talk to you.

Most engineers overthink their resume because they're trying to make it perfect. Perfect doesn't exist. Good enough to get interviews does. Focus on: clear impact, relevant skills, scannable format, and zero errors.

Do that, and you'll get more interviews. Then the real work begins.

Frequently Asked Questions

How long should my tech resume be?

One page for engineers with less than 5 years of experience. Two pages maximum for senior engineers. Anything longer and you're not being selective enough. Recruiters spend 6-10 seconds on initial screen—if they have to scroll through 3 pages, you've already lost.

Should I use a fancy resume template or design?

No. Use a clean, simple template that ATS systems can parse easily. Fancy designs with graphics, columns, or unusual formatting break ATS parsing and your resume gets rejected automatically. Stick to standard sections, clear headers, and simple formatting. Boring works.

What's the biggest resume mistake engineers make?

Listing responsibilities instead of accomplishments. Your resume shouldn't be a job description—it should show impact. Instead of "Responsible for backend services," write "Built payment processing system handling $50M annually, reducing transaction failures by 60%." Show results, not duties.

Do I need to include all my past jobs on my resume?

No. Include relevant experience from the last 10-12 years max. Older roles can be summarized in one line or omitted entirely. Focus on quality over comprehensiveness—showcase your best, most relevant work. Every line should strengthen your case for the job you want.

How do I get my resume past ATS systems?

Use standard section headers (Experience, Education, Skills). Include relevant keywords from the job description naturally in your bullet points. Avoid tables, graphics, headers/footers, and unusual fonts. Use a simple format with clear hierarchy. Save as .docx or .pdf (check which the ATS accepts). Most importantly, tailor your resume for each role.
