If you are a developer applying for jobs and getting no replies, this post might sting a little.
Because the first person reviewing your resume is not a recruiter.
It is an algorithm.
The First Interview Is With Software
Most tech companies use Applicant Tracking Systems to filter resumes. These systems parse your resume, extract text, and score it before a human looks at anything.
If the system cannot read your resume properly, you are rejected automatically.
No feedback. No signal. Just silence.
This is why people with solid experience and real projects still get ghosted.
Why Developers Are Especially Vulnerable
Many developers treat resumes like UI problems.
Columns. Icons. GitHub logos. Fancy layouts. Creative section titles.
They look great to humans. They break ATS parsing.
ATS software struggles with:
- Multi column layouts
- Tables and text boxes
- Icons and images
- Headers and footers
- Non standard section names
If your resume is not machine readable, your experience does not matter.
ATS Is Basically a Parser With Opinions
Think of ATS like a strict parser.
If the input format is wrong, it fails silently.
If keywords do not match expected tokens, you score lower.
If sections are not named clearly, data gets lost.
You would never ship code without testing it. Yet most people ship resumes without validating how they are parsed.
Keywords Are Not Buzzwords
A common mistake is assuming ATS optimization means keyword stuffing. That is not how modern systems work.
ATS looks for relevant keywords that reflect actual experience.
If a job description mentions:
- React
- TypeScript
- AWS
- CI/CD
And your resume uses vague language or omits those terms entirely, the system assumes you are not a match.
This is less about gaming the system and more about speaking its language.
I Ran My Resume Through an ATS Checker
Out of curiosity, I tested my resume using an ATS resume checker.
What I found was uncomfortable:
- Sections were parsed incorrectly
- Some experience was skipped entirely
- Keywords I clearly had experience with were missing
- Formatting choices broke text extraction
- None of this was obvious by looking at the resume.
After making small changes, the ATS score improved significantly without changing my actual experience.

The Resume Advice Most Devs Get Is Wrong
Most resume advice online focuses on aesthetics.
Hiring pipelines do not.
Your resume has two jobs:
- Pass automated screening
- Be readable by a human in under ten seconds
Design heavy resumes often fail at step one.
Simple resumes survive.
A Practical Checklist for Devs
If you want your resume to survive ATS screening, start here:
- Use a single column layout
- Avoid icons, logos, and graphics
- Use standard section titles like Work Experience and Skills
- Include keywords from the job description naturally
- Use a text based PDF or DOCX
- Test your resume before applying
This is boring advice. It works.
The Market Is Competitive, Not Personal
If you are feeling stuck or discouraged, it is important to understand this.
Rejection does not always mean you are underqualified.
Sometimes it means your resume failed a parsing step you did not know existed.
Once you understand that hiring is partially an optimization problem, things start to make more sense.
Final Thought
Developers obsess over tooling, testing, and optimization in every part of their work.
Your resume deserves the same treatment.
Do not let an untested input file block your career.
If this helped you, consider sharing it with someone who is job hunting.
They are probably blaming themselves for a problem caused by software.
