India's Big 5 IT service companies — TCS, Infosys, Wipro, HCL, and Cognizant — together hire over 1.5 lakh engineers every year. While they all appear similar, each has subtle differences in what their ATS and HR teams prioritise.

This guide breaks down what each company looks for, how to format your resume for their portals, and the six silent rejection reasons most candidates never realise.

Universal Rules for IT Service Company Resumes

Before the company-specific tips, these rules apply everywhere:

• Format: Reverse-chronological, 1–2 pages max
• Font: Calibri or Arial, 10–11pt body, 12–14pt headings
• File format: PDF for most portals; .docx if TCS iBegin or iMocha requires it
• No photos, no columns, no tables in the header
• Include measurable outcomes for every role and project

Company-Specific ATS Keywords

TCS (Tata Consultancy Services)

TCS's iBegin portal runs keyword matching before human review. Priority keywords:

• Java, Python, C#, .NET, Spring Boot, Angular, React
• Agile, Scrum, SDLC, DevOps, CI/CD
• BFSI, Healthcare, Retail (mention domain exposure if any)
• Communication Skills, Client Interaction, Stakeholder Management
• TCS iON, TCS BaNCS, iTransform (if you've worked with these)

Infosys

Infosys screens for both technical depth and learning mindset. Key terms:

• Generative AI, LLM, Machine Learning, Data Science (2026 priority)
• Springboard (Infosys's internal learning platform — mention if used)
• SAP, Oracle, ServiceNow (ERP/enterprise tool experience)
• Continuous Learning, Self-Motivated, Problem Solving
• Automation Testing, Selenium, JUnit, TestNG

Wipro

Wipro's ELITE and Turbo programmes have different bars. For ELITE:

• Cloud: AWS, Azure, GCP (even basic certification counts)
• Cybersecurity, Network Security (high demand in 2026)
• Full Stack Development, Microservices, Kubernetes
• VLSI, Embedded Systems (for ECE/EEE streams)

HCL Technologies

• Digital Transformation, Cloud Migration, SAP S/4HANA
• JavaScript, TypeScript, React, Vue.js
• ITIL, IT Service Management, Service Desk
• Proactive, Initiative, Customer Focus

Cognizant (GenC / GenC Next)

• AI/ML, Data Analytics, Power BI, Tableau
• Python, SQL, R, Excel (for analytics roles)
• Collaboration, Adaptability, Growth Mindset
• Healthcare IT, Insurance, Banking domain knowledge

Section-by-Section Format Guide

Professional Summary (3–4 lines)

Lead with years of experience, primary tech stack, and one key achievement. Example: "Software Engineer with 2 years at a product startup, specialised in Python/Django REST APIs and PostgreSQL. Reduced API response time by 40% through query optimisation. Seeking an Infosys role in data engineering."

Work Experience

Use strong action verbs: Designed, Implemented, Optimised, Automated, Delivered, Migrated, Led, Reduced, Increased. Each bullet = Action + Metric + Business Impact.

Skills

Create a clearly labelled "Technical Skills" section. Separate by category. List only what you can speak to in an interview — lying about skills is the #1 reason for immediate rejection after clearing ATS.

The 6 Silent Rejection Reasons

1. CGPA below cutoff listed without context — if your CGPA is low, don't draw attention to it; focus on projects and achievements
2. Job gaps with no explanation — add a brief note (e.g., "Family commitment", "Freelance project") to fill visible gaps
3. Generic objective — copy-pasted objectives are spotted instantly by experienced HR teams
4. Mismatched role keywords — applying for a testing role with only development keywords triggers ATS rejection
5. PDF with scanned text — text inside images can't be parsed; always use a text-based PDF
6. No measurable outcomes — "Worked on Java project" tells recruiters nothing; "Built REST API in Java serving 50K daily requests" is memorable
