What is an ATS?
An applicant tracking system (ATS) is software that employers and recruiters use to collect job applications, store candidate records, and search and filter them. Common examples include Workday, Greenhouse, Lever, Taleo and iCIMS, but employers configure them very differently, and many small employers use none at all.
In most systems a person still makes the hiring decision. The ATS mainly organises applications and lets recruiters search them, for example by skill, job title or location. Some employers also set knock-out questions (such as work authorisation or a required degree) that filter applications automatically.
How resume parsing works
When you upload a resume, the system usually tries to extract the text and sort it into fields: name, contact details, job titles, employers, dates, education and skills. This step is called parsing. Recruiters then see either the parsed fields, your original file, or both.
Parsers work best when the file contains real, selectable text in a predictable order with recognisable headings. They can struggle when information is placed in unusual spots or encoded as images. If a parser misreads your dates or job titles, the recruiter's search results and candidate profile can end up wrong, even though your resume looks fine to you.
Formatting considerations
- Use a simple, top-to-bottom structure. Single-column layouts are the least likely to be read out of order. Multi-column designs can work in some systems, but they carry more risk.
- Use standard section headings such as Work Experience, Education, Skills and Projects rather than creative labels.
- Keep key details in the main body. Some parsers ignore page headers and footers, so avoid putting your name or contact details only there.
- Avoid text inside images, icons and skill-rating bars. Graphics cannot be read as text.
- Use consistent, common date formats (for example "Jun 2024 – Aug 2025") and standard fonts.
- Use tables sparingly. Parsers may read cells in an unexpected order.
File-format considerations
Follow the employer's instructions first. If the application does not specify, a PDF exported from a word processor or resume builder keeps your layout and normally contains selectable text. A .docx file is also widely accepted. A scanned page or a PDF made from a picture contains no text for the system to read, so avoid it. Check that you can select and copy text in your PDF before uploading.
Keywords and job descriptions
Recruiters often search their ATS with skills, tools and job titles. Read the job description and note the skills, tools and phrases it repeats. Where they honestly describe your experience, use the same wording, including the full name and the abbreviation the first time (for example, "Search Engine Optimisation (SEO)").
Do not paste in keywords you cannot back up, and do not hide text in white font. Recruiters and interviewers will test what your resume claims, and repeating a term dozens of times does not make it more relevant.
Skills, experience and education sections
Skills
Give skills their own clearly labelled section as a plain list, grouped if helpful (for example Languages, Frameworks, Tools). Then show the same skills in use in your experience or projects, since a list alone does not prove anything.
Experience
For each role, put the job title, employer, location and dates on predictable lines, followed by short bullets. Start bullets with action verbs and add numbers where you honestly can. Freshers can use internships, academic projects, hackathons and volunteer work in the same format.
Education
List the degree, institution, and start and end (or expected) dates in a consistent format. Freshers often place Education above Experience; either order parses fine as long as headings are standard.
Common problems
- A resume exported as an image, or a scan with no selectable text.
- Name and contact details placed only in the page header or in a text box.
- Heavily designed templates with columns, icons and progress bars that scramble reading order.
- Creative section names the parser does not recognise.
- Skills in the job description that appear nowhere on the resume, even though you have them.
- Inconsistent dates or job titles that do not match your other profiles.

What cannot be guaranteed
No resume format or tool can guarantee that a particular ATS will parse it perfectly, rank it highly or lead to an interview. Systems differ, employers change their settings, and people make the final decisions. The best approach is to keep the file simple, keep the content honest and relevant to the role, and check the result by copying the text out of your PDF.
SmartCampusBuddy's templates use standard headings, and the builder includes an ATS panel that flags common formatting, keyword and completeness issues as you write. It is a checklist to help you review your resume, not a guarantee about any employer's system.
