Why did I get rejected from a React job when I have 4 years of React experience?

Probably because you wrote "React.js" and they searched for "React", or you wrote "React" and they wanted "ReactJS". ATS keyword matching is stupidly literal. **The stupid shit that causes rejections:** - Job posting: "JavaScript developer" → Your resume: "JS developer" → No match - Job posting: "PostgreSQL" → Your resume: "Postgres" → No match - Job posting: "Node.js" → Your resume: "NodeJS" → No match Copy the exact technology names from the job posting. I know it's ridiculous, but that's how these systems work.

Should I put "Senior" in my title if I'm not officially senior?

Fuck no. Don't lie about your level. But if your actual title was "Software Engineer III" and you're applying to "Senior Software Engineer" roles, you can use "Senior Software Engineer" if that accurately reflects your level. Title matching matters for ATS filtering. If they're filtering for "Senior" and you only have "Software Engineer", you might get filtered out even if you have senior-level experience.

How do I handle contract work that ATS systems hate?

ATS systems are garbage at parsing contract work. They expect: ``` JOB TITLE Company Name Start Date - End Date ``` For contract work, format it like: ``` SENIOR FRONTEND DEVELOPER (CONTRACT) Client Company Name (via Consulting Firm) Jan 2023 - Dec 2023 ``` Don't try to get clever with "Consulting Firm → Client Company" because Workday will think your job title is "Client Company".

Why does Workday keep asking me to re-enter everything?

Because Workday's PDF parsing is hot garbage. Their system probably: - Extracted your name as "SOFTWARE" (if it was in a header) - Missed your phone number entirely - Thought your GitHub URL was your job title - Completely ignored your work experience section There's no fix except manually re-entering everything in their shitty form interface. Takes 30-45 minutes per application. It's fucking painful.

Do I need different resumes for startups vs big companies?

**Startups (usually Greenhouse/Lever):** - Can handle PDFs better - More flexible keyword matching - Single-column layouts still safer - Can get away with slightly more creative formatting **Enterprise (Workday/iCIMS):** - Submit Word docs if possible - Exact keyword matching required - Boring formatting mandatory - Expect to re-enter everything manually anyway Same content, different formats. Keep the startup version as your "nice" resume and the enterprise version as your "ATS survival" format.

How do I show full-stack experience without confusing parsers?

Don't use "Full Stack Developer" as your title - ATS systems don't know what that means for filtering. Use "Software Engineer" or "Frontend Developer" or "Backend Developer" based on what you spent most time doing. **In your experience bullets:** - "Built React frontend that integrates with Node.js REST API" - "Developed Python backend services with PostgreSQL database" - "Implemented end-to-end features from React components to database queries" This shows full-stack work while using specific technology keywords the ATS can match.

Should I include side projects if I have professional experience?

Yes, if they're relevant and demonstrate skills not shown in your day job. But format them properly: **Don't do this:** ``` Personal Projects - Todo app with React - Weather API thing ``` **Do this:** ``` PERSONAL PROJECTS Task Management Application (2023) - Built full-stack app with React 18, Node.js, and PostgreSQL - Implemented user authentication and real-time updates with WebSockets - Deployed to AWS using Docker containers - Code: github.com/username/task-app ``` Make side projects look as professional as your day job work.

Why do enterprise applications take forever to hear back?

Because their process is: 1. ATS filters 80% of resumes automatically 2. HR screens the remaining 20% for obvious mismatches 3. Hiring manager finally sees maybe 5% of original applications 4. Process takes 6-8 weeks minimum If you applied and never heard back, you probably got filtered out at step 1. Not because you're unqualified, but because Workday couldn't parse your resume properly.

Is Arc's format actually different or just marketing?

Arc's templates avoid the specific formatting that breaks ATS parsing. I tested my old resume vs Arc's format on the same job applications: **Old resume (creative design):** 7/25 applications got past initial screening **Arc format (boring but functional):** 18/25 applications got past screening Same experience, same keywords, just different formatting. The difference is Arc knows which specific formatting choices break which specific ATS systems. It's not magic, it's just debugging why resumes disappear into ATS black holes and fixing those specific issues. Alright, you want to fix your own ATS problems? Here are the tools and resources that actually work, not the marketing bullshit that everyone else recommends.

ATS Resume Optimization: Technical Implementation Guide

Executive Summary

Applicant Tracking Systems (ATS) fail to parse 70-80% of resumes correctly due to poor PDF parsing, strict keyword matching, and format incompatibility. Testing shows response rates improve from 5% to 35% when using ATS-optimized formatting versus creative designs.

ATS System-Specific Failure Modes

Workday (Enterprise Standard)

Critical Issues:

PDF header/footer extraction fails completely
Name extracted as job title from headers
Manual re-entry required: 30-45 minutes per application
Parsing accuracy: ~20% for standard resume formats

Breaking Points:

Contact info in document headers → invisible to parser
Custom fonts → garbled text extraction
Multi-column layouts → scrambled content order

Greenhouse (Startup Standard)

Critical Issues:

Cannot read document headers
Date format sensitivity: "January 2023" fails, "Jan 2023" works
Skills extraction is keyword-literal only

Breaking Points:

Sidebar content completely ignored
Technology versions don't match base keywords (React 18 ≠ React)

iCIMS (Large Enterprise)

Critical Issues:

Keyword matching requires exact strings
Contact info in tables becomes invisible
Job title parsing splits on commas/special characters

Example Failure:

Resume: "Python engineer" → Job posting: "Python developer" → No match

BambooHR/Smaller Systems

Critical Issues:

Job title parsing: "Senior Software Engineer, Platform Team" → Company = "Platform Team"
Cannot handle complex employment structures

Technical Formatting Requirements

Contact Information Structure

Fails:

┌─────────────────────────────┐
│ John Developer              │
│ john@email.com | (555) 123  │
└─────────────────────────────┘

Works:

John Developer
john@email.com
(555) 123-4567
github.com/john

Employment History Format

Fails:

Software Engineer | Company Name | March 2022 - Present

Works:

SOFTWARE ENGINEER
Company Name, Inc.
March 2022 - Present

Technology Naming Critical Requirements

Technology	Required Variations	Common Failures
React	"React", "React.js", "ReactJS", "React 18"	"React.js" ≠ "React"
Node.js	"Node.js", "NodeJS", "Node"	"Node" ≠ "Node.js"
PostgreSQL	"PostgreSQL", "Postgres"	"Postgres" ≠ "PostgreSQL"
JavaScript	"JavaScript", "JS" (list both)	"JS" ≠ "JavaScript"
AWS	"AWS", "Amazon Web Services", specific services	"AWS" ≠ "EC2"

Implementation Specifications

Date Format Standards

Use: "Mar 2023 - Present"
Avoid: "March 2023", "03/2023", "2023-03"
Failure rate with wrong format: 60%

Section Headers (Use Exact Terms)

"Work Experience" (not "Professional Experience")
"Skills" (not "Technical Competencies")
"Education" (not "Academic Background")

File Format Requirements

PDF: Better visual preservation, worse parsing (30% failure rate)
Word (.docx): Better parsing, format degradation
Enterprise systems: Submit both formats when possible

Quality Assurance Testing Protocol

Step 1: Plain Text Extraction Test

# Copy entire resume → paste into Notepad
# If structure breaks, ATS will fail

Step 2: Automated Parsing Test

Upload to Jobscan.co with real job posting
Check keyword match percentage
Identify missing technology names

Step 3: Multi-format Testing

Test both PDF and Word versions
Upload to actual company ATS systems
Document parsing differences
