An applicant tracking system is software employers use to receive, store, and search resumes. It parses your resume into fields and lets recruiters search by keyword, so formatting it cleanly matters as much as what it says.

Is a PDF or Word document better for an ATS?

Both work if the file is text-based, not a scanned image. A Word document (.docx) is the safest default. Never send a photographed or scanned resume, because the software cannot read the text.

ATS-friendly resume: how to pass the screening in India

Q: How many keywords should I add?

Use the genuine skills and terms from the job description, written naturally in your summary, experience, and skills sections. Do not stuff or hide keywords. Modern systems and recruiters both penalise it.

Most mid-size and large employers in India route applications through an applicant tracking system, or ATS, before a human sees them. If the software cannot read your resume, or cannot find the terms it is searching for, a strong candidate can be filtered out before anyone reads a word. The good news: passing an ATS is not about tricks. It is about a clean format and honest, relevant wording. Here is what to do.

What an ATS actually does

An ATS receives your file, parses it into structured fields (name, roles, dates, skills), and stores it so a recruiter can search the database by keyword, for example "credit risk Mumbai FRM". Two things follow from this. First, the system has to be able to read your file cleanly. Second, the terms a recruiter searches for need to actually appear in your resume. Most ATS failures come down to one of these two problems.

Formatting rules that keep you readable

Use a single-column layout. Multi-column and table-based designs often parse out of order or get scrambled.
Avoid tables, text boxes, and graphics for content. Many parsers ignore them.
Keep contact details in the body, never in the page header or footer, which some systems do not read.
Use standard section headings: "Experience", "Education", "Skills". Creative headings confuse the parser.
Use a common font and simple bullets. No skill rating bars, no icons.
Save as a text-based Word document or PDF, never a scanned image or photo.

Our resume format guide shows a layout that follows all of this.

Keywords: match the job, do not stuff it

Read the job description and note the exact terms it uses for skills and qualifications. Then make sure the genuine ones appear naturally in your summary, experience, and skills sections, in the same words. If the role asks for "regulatory reporting" and "SQL", use those phrases rather than vaguer equivalents.

Do not stuff keywords, repeat them unnaturally, or hide white text in the document. Modern systems flag it and recruiters reject it. Relevance beats volume: a resume that honestly matches the role will out-perform one crammed with terms.

Test before you send

Copy all the text from your resume and paste it into a plain document. If the order is jumbled or text is missing, the ATS will struggle too.
Check that every role has a clear title, employer, and dates in a consistent format.
Re-read the job description and confirm its key terms appear, in context, in your resume.
