High-Impact Mistakes
Critical errors that cause immediate rejection
These mistakes have the highest probability of getting your Software Engineer resume rejected. Fix these first before addressing anything else.
Using graphics, icons, or images for skills
ATS systems cannot parse visual elements. Your skills section becomes invisible to automated screening.
How to Fix
Use plain text lists with clear skill names. Format as comma-separated or bulleted lists.
Listing technologies without context or metrics
Simply listing 'Python, JavaScript, React' doesn't show competency level or impact.
How to Fix
Show how you used each technology: 'Built React dashboard reducing load time by 40%'
Using creative multi-column layouts
ATS systems read left-to-right, top-to-bottom. Multi-column layouts scramble your content.
How to Fix
Stick to single-column, top-to-bottom format with clear section headers.
Generic job descriptions instead of achievements
'Developed software applications' tells recruiters nothing about your impact.
How to Fix
Quantify achievements: 'Reduced API response time by 60% serving 10M daily requests'
Missing exact keywords from job description
ATS filters resumes based on keyword matching. Missing keywords = automatic rejection.
How to Fix
Mirror exact terminology from the job posting. If they say 'TypeScript', don't write 'TS'.
Using tables or text boxes for formatting
Tables and text boxes are parsed incorrectly by most ATS systems.
How to Fix
Use standard paragraph formatting with clear headings and bullet points.
Medium-Impact Mistakes
Errors that reduce your interview chances
These mistakes won't necessarily cause automatic rejection, but they weaken your candidacy and reduce your chances of landing interviews.
Saving PDF with embedded or custom fonts
Custom fonts may not render correctly and can cause text parsing failures.
How to Fix
Use standard fonts: Arial, Calibri, Times New Roman, or Helvetica.
Including every technology you've ever used
Long skill lists dilute your expertise and may include outdated technologies.
How to Fix
Focus on 12-15 most relevant skills that match the target role.
Not including a professional summary
Recruiters spend 6 seconds on initial scan. No summary means no quick hook.
How to Fix
Write 2-3 sentence summary highlighting years of experience, key skills, and notable achievement.
Omitting links to GitHub or portfolio
Software roles expect to see code samples. Missing links raise questions about your work.
How to Fix
Include GitHub profile and 2-3 notable project links in your header.
