Common Mistakes That Kill Your Chances

Each mistake includes why it hurts, how to fix it, and before/after examples

No Portfolio or Live Demo LinksHIGH
Why it hurts
  • Hiring managers can’t verify your UI/UX skills
  • ATS may lower relevance score for missing project URLs
  • Missed chance to showcase interactive work
How to fix
  • Add a dedicated 'Portfolio' line with a clickable URL
  • Include short descriptions with tech stack for each project
  • Host demos on GitHub Pages, Netlify, or Vercel
❌ Before

John Doe Frontend Developer johndoe@email.com ...

✓ After

John Doe Frontend Developer johndoe@email.com | Portfolio: https://johndoe.dev ...

ATS Tip
Use the exact word "Portfolio" in the heading; many parsers look for it.
Detection Rules
Missing regex pattern for https?://.*(github|netlify|vercel)
Resumly Tip
Add a live link to at least two recent projects to prove your front‑end chops.
Overly Generic Skills ListMEDIUM
Why it hurts
  • ATS can’t match specific tech keywords
  • Recruiters see you as a jack‑of‑all‑trades, master of none
  • Reduces perceived seniority
How to fix
  • Replace broad terms like "Web Development" with concrete tools
  • Group skills by category (Frameworks, Build Tools, Testing)
  • Prioritize the stack mentioned in the job posting
❌ Before

Skills: Web Development, Programming, Design

✓ After

Technical Skills: - Frameworks: React, Next.js, Vue.js - Languages: JavaScript, TypeScript, HTML5, CSS3 - Tools: Git, Webpack, Vite, Jest, Cypress

ATS Tip
Match at least 5 exact keywords from the job description.
Detection Rules
Presence of generic terms without specific tech names
Resumly Tip
Swap vague buzzwords for the exact libraries and tools you use daily.
Listing Outdated TechnologiesLOW
Why it hurts
  • Signals that you’re not keeping up with industry trends
  • ATS may penalize resumes that mention deprecated tech
  • Hiring managers may doubt current relevance
How to fix
  • Remove legacy items like jQuery unless required
  • Highlight modern equivalents (e.g., React, Vue, Svelte)
  • If you must list older tech, place it under a "Legacy Projects" sub‑section
❌ Before

Technologies: jQuery, Backbone.js, CSS2

✓ After

Modern Stack: React, Next.js, Tailwind CSS, TypeScript

ATS Tip
Focus on the top 5 technologies from the posting; older tools belong in a separate section.
Detection Rules
Detection of keywords such as "jQuery" or "Backbone" without accompanying modern equivalents
Resumly Tip
Show that you’re current—swap old libraries for the latest frameworks you actually use.
Unclear Project DescriptionsHIGH
Why it hurts
  • Recruiters can’t gauge impact or scope
  • ATS may miss key action verbs and results
  • Lacks quantifiable achievements
How to fix
  • Start each bullet with a strong verb (e.g., "Implemented", "Optimized")
  • Include metrics (e.g., "Reduced load time by 30%")
  • Mention the tech stack used in the project
❌ Before

- Worked on a web app. - Fixed bugs. - Added features.

✓ After

- Implemented a responsive UI for a SaaS dashboard using React and Tailwind CSS, increasing user engagement by 22%. - Optimized asset loading with Webpack code‑splitting, reducing page load time from 4.2 s to 2.8 s. - Refactored legacy components to TypeScript, cutting runtime errors by 15%.

ATS Tip
Include at least one keyword from the job description in each project bullet.
Detection Rules
Bullets lacking action verbs or measurable outcomes
Resumly Tip
Turn vague tasks into achievement‑focused statements with numbers and tech details.
Ignoring ATS‑Friendly HeadingsMEDIUM
Why it hurts
  • ATS may fail to map content to standard sections
  • Recruiters spend extra time parsing unconventional layouts
  • Important info can be missed
How to fix
  • Use conventional headings: "Professional Summary", "Technical Skills", "Projects", "Work Experience", "Education"
  • Avoid decorative symbols or creative titles like "My Journey"
  • Keep heading hierarchy clear (H1 for name, H2 for sections)
❌ Before

Professional Summary Technical Skills Projects Work Experience Education

ATS Tip
Exact heading text improves parsing accuracy across Greenhouse, Lever, iCIMS, and Workday.
