How to Optimize Your Resume for ATS and Get More Job Interview Calls in 2025

Introduction

If you've been applying to multiple companies without success, your resume might be falling victim to Applicant Tracking Systems (ATS). These systems are designed to scan, rank, and filter resumes before they even reach a human recruiter.

According to Jobscan, approximately 75% of resumes are rejected by ATS before a human recruiter ever sees them. This makes ATS optimization critical for every job seeker in 2025.

Many job seekers face a common frustration: despite applying to numerous companies, their resumes don't get shortlisted. The root cause is often not a lack of qualifications but how resumes are structured and presented to Applicant Tracking Systems.

The good news? With the right optimization strategies—and tools like Resumoid—you can dramatically increase your chances of getting shortlisted.

In this comprehensive guide, we'll dive into what an ATS is, how to optimize your resume for it, and proven strategies to boost your chances of landing interview calls.

What Is an ATS and Why Does It Matter?

An Applicant Tracking System (ATS) is software used by companies and recruitment agencies to manage job applications at scale. Instead of manually reviewing hundreds or thousands of resumes, ATS automates the initial screening process.

How ATS Works

ATS scans resumes for:

Keyword Matches: Skills, qualifications, tools, and job titles mentioned in the job description
Formatting and Structure: Easy-to-read text, clear sections, and standard layouts
Relevance to the Job: Your experience, education, and skills must align with job requirements

The ATS ranks candidates based on how well their resumes match the job description. If your resume doesn't meet these criteria, it may never reach a human recruiter—even if you're the perfect candidate.

Why ATS Matters More in 2025

With remote hiring on the rise and AI tools being integrated into every step of recruitment, ATS systems are more sophisticated than ever. Many now use natural language processing (NLP) and AI algorithms to understand context and intent. But they're still not perfect, and formatting mistakes or missing keywords can hurt your chances.

Key Insight: Over 90% of Fortune 500 companies use ATS to manage applications. Understanding how these systems work gives you a significant advantage.

10 Proven Ways to Make Your Resume ATS-Friendly

1. Analyze the Job Description Carefully

Start every resume customization by carefully reading the job posting. Identify:

Required skills and technologies
Key responsibilities and duties
Preferred qualifications
Industry-specific terminology

Highlight these keywords—you'll use them throughout your resume's Skills, Work Experience, and Summary sections.

2. Match Keywords from the Job Description

Don't just stuff keywords randomly. Incorporate them naturally in your resume:

Professional Summary: "Android Developer with expertise in Kotlin, Java, and Firebase"
Skills Section: List specific tools and technologies mentioned in the job
Work Experience: Describe how you used those skills to solve real problems

Pro Tip: When a job posting mentions "project management," use exactly that phrase rather than "managing projects." ATS systems often search for specific keywords, and synonyms don't always register.

3. Tailor Your Resume for Each Job

Generic resumes significantly reduce your chances. Customize your resume for every application by:

Reordering skills to highlight the most relevant ones first
Emphasizing achievements that match job requirements
Using the company's terminology and language

Yes, this takes more time—but studies show that tailoring your resume can increase your interview chances by up to 3.5 times.

4. Craft a Professional Summary

Start your resume with a brief summary (3-4 lines) that aligns with the role:

Strong Example:

"Result-oriented Android Developer with 5+ years of experience in developing scalable mobile apps, proficient in Kotlin, Java, and Jetpack Compose. Adept at leading projects and delivering user-centric solutions with proven track record of improving app performance by 30%+."

Why This Works:

Immediately establishes relevance
Includes key keywords (Kotlin, Java, Jetpack Compose)
Mentions quantifiable achievements (30% improvement)

5. Focus on Relevant Skills

Include both technical and soft skills in a dedicated Skills section:

Technical Skills:

Programming Languages: Kotlin, Java, XML, Python
Frameworks & Libraries: Jetpack Compose, Retrofit, Dagger, Coroutines
Tools: Android Studio, Firebase, Git, Jira, Jenkins
APIs: REST APIs, GraphQL, Google Maps API

Soft Skills:

Team Collaboration
Problem-Solving
Communication
Project Management

ATS often searches specifically for a "Skills" keyword section—make sure yours is clearly labeled.

6. Detail Your Work Experience with Action Verbs and Metrics

Start bullet points with strong action verbs and quantify your achievements:

Action Verbs: Developed, Designed, Implemented, Optimized, Led, Improved, Created, Managed, Launched

Before (Weak):

"Worked on mobile app development"

After (Strong):

"Developed a feature-rich e-commerce app with 50k+ downloads in 6 months, optimizing app performance and reducing load time by 30%"

The second version uses action verbs, includes specific results, and demonstrates measurable impact.

7. Format Your Resume Properly

DO:

Use a single-column layout
Employ standard fonts (Arial, Times New Roman, Calibri) at 11-12pt
Use consistent bullet points
Include clear section headings (Professional Summary, Skills, Experience, Education)
Add white space for readability

DON'T:

Use multi-column layouts
Include images, logos, or graphics
Add colored text or backgrounds
Use tables, text boxes, or headers/footers with content

8. Avoid Images and Special Characters

ATS may not read images, logos, or symbols correctly. Avoid:

Photos or headshots
Emojis or special symbols (★, ✓, ●)
Colored backgrounds or fancy designs
Charts, infographics, or diagrams

Stick to plain, simple text formatting for maximum ATS compatibility.

9. Include Certifications and Tools

Mention relevant certifications prominently:

Google Certified Associate Android Developer
AWS Certified Solutions Architect
Project Management Professional (PMP)

List tools and platforms you've used: Android Studio, Git, Jira, Figma, Firebase, Docker, Jenkins.

10. Save Your File in the Right Format

Most ATS systems prefer:

.docx (Microsoft Word) — Most compatible
.pdf — Check job requirements first; some ATS struggle with PDFs

Pro Tip: Unless the job posting explicitly asks for a PDF, submit your resume in .docx format for best results.

How to Increase Your Chances of Being Shortlisted

Beyond resume optimization, these strategies will significantly boost your interview rate:

1. Customize Your Resume for Every Application

Tailor your resume to match the specific job role. Highlight skills and experiences that are most relevant—generic resumes get filtered out quickly.

2. Build a Strong Online Presence

Update your LinkedIn profile with your latest projects, skills, and achievements. According to LinkedIn's official career advice, profiles with complete information receive 40x more opportunities than incomplete ones.

Add a professional headshot
Include relevant keywords in your headline and summary
Share articles and participate in industry discussions
Get recommendations from colleagues and managers

3. Highlight Projects in Your Portfolio

Add links to your portfolio in your resume:

GitHub Profile: Showcase your code and open-source contributions
Personal Website: Display your best work and case studies
App Store Links: If you've published apps, include download links
Project Demos: Videos or live links demonstrating your skills

4. Use Job Portals Effectively

Apply on multiple platforms strategically:

Use advanced filters to find jobs tailored to your skills. Set up job alerts for your target roles.

5. Get Referrals

Network with professionals in your field. Employee referrals bypass ATS entirely and significantly increase your chances:

Ask your network for referrals to companies you're applying to
Attend industry events and conferences
Join online communities on Reddit, Discord, and GitHub
Connect with recruiters directly on LinkedIn

6. Write a Personalized Cover Letter

A well-written cover letter can set you apart:

Explain why you're excited about the specific role
Highlight how your experience solves the company's problems
Demonstrate knowledge of the company
Show cultural fit in 3-4 concise paragraphs

7. Follow Up with HR

After applying, send a polite follow-up email to HR after 1-2 weeks:

"Hi [Recruiter Name],
I applied for the [Job Title] position on [Date]. I'm very interested in this opportunity and would love to discuss how my experience in [specific skill] can contribute to your team.
Would you have time this week for a quick call?
Best regards,
[Your Name]"

This shows genuine interest and keeps you top-of-mind.

Common Resume Mistakes to Avoid

Generic Resumes

Using the same resume for every application reduces its impact. Always tailor it for the specific role.

Lack of Focus

Avoid cluttering your resume with irrelevant skills, outdated experiences, or unnecessary personal information.

Grammar and Spelling Errors

Proofread thoroughly. Grammar errors signal carelessness and can hurt your ATS score.

Unclear Job Titles

Use standard titles like "Software Developer" instead of creative ones like "Code Wizard." ATS recognizes standard titles; creative ones confuse the system.

Inconsistent Formatting

Use the same bullet point style, date format, and spacing throughout. Inconsistency confuses ATS parsing.
