Here’s what makes a resume truly ATS-friendly and optimized for IT careers:

• Simple, clean layout: Use standard headings like “Experience”, “Education”, “Skills”, avoid graphics, images, or complex tables.
• Relevant keyword usage: Pull keywords from the job posting (e.g. “Python”, “Kubernetes”, “unit testing”) and include them in the Skills, Summary, and Experience sections.
• Action + result statements: Describe what you did and what you achieved. Use quantifiable metrics whenever possible. This aligns with advice from Yale’s career guidance on accomplishment statements.
• Reverse chronological order: Put your most recent and relevant roles first. It helps both ATS parsing and recruiter quick-review.
• Technical skills section: Clearly list programming languages, tools, frameworks, platforms relevant to the job. Avoid hiding them in long paragraphs.
• Consistent formatting: Use standard fonts (Arial, Calibri, Verdana), sizes (10-12 pt), consistent bullet styles and spacing. From Harvard guidance: simple, factual, no flowery language.
• File type: Usually a .docx and PDF are accepted. But avoid formats that may not parse well (e.g. some PDFs exported with images). Some ATS parse better if you upload .docx. Always test or check employer guidelines.
