Most job seekers have heard some version of the same warning: your resume is probably getting rejected by a robot before a human ever reads it. It’s repeated so often that it’s basically accepted as fact, and it shapes how people write resumes, sometimes into strange, keyword-stuffed documents that read worse to an actual hiring manager than they would have without the “optimization.” As a leading recruitment firm in USA, we see both sides of this. We see the resumes candidates submit, and we see what actually happens to them once they land in a company’s hiring system. The two don’t always match the popular narrative.
This piece looks at what applicant tracking systems really do, where the common advice gets it wrong, and what actually improves a resume’s chances, both with the software and with the person who eventually reads it.
The “75% Rejected by Robots” Myth Needs to Go
The statistic that gets quoted constantly, that roughly three out of four resumes are rejected by ATS software before a human ever sees them, does not hold up well under scrutiny. It traces back to a 2012 sales pitch from a company called Preptel, which sold resume optimization services and shut down the following year without ever publishing a methodology behind the number. More recent reporting, including interviews with practicing recruiters conducted by the resume platform Enhancv in late 2025, points to something closer to the opposite: most ATS platforms don’t auto-reject resumes based on content at all. They organize and rank applications so a person can review them faster.
That doesn’t mean formatting and keywords don’t matter. They do. It means the mechanism is different from what most job seekers have been told, and understanding the real mechanism leads to better decisions than chasing a myth.
What an ATS Actually Does
An applicant tracking system is software that reads a submitted resume, pulls out structured information such as job titles, dates, and skills, and stores it alongside every other application for that role. Most systems then score or rank candidates against the job requisition so a recruiter can sort through a stack of two hundred applications more efficiently than reading each one cold. It’s a filing and ranking tool first, not a judge handing down rejections on its own.
The part that actually screens people out before a human looks at anything is usually a set of knockout questions the employer configured directly: whether a candidate has the right to work in the country, whether they meet a minimum years-of-experience requirement, whether they’re willing to relocate. Those are deliberate choices made by the hiring team, not a hidden penalty for using the wrong font.
Formatting Choices That Help, and Ones That Quietly Hurt
Even with auto-rejection largely off the table, formatting still affects how accurately a resume gets parsed, and a badly parsed resume can look incomplete or garbled by the time a recruiter opens it.
Where Formatting Quietly Backfires
A handful of habits account for most of the trouble:
- Tables and multi-column layouts– Some systems read them out of order or skip sections entirely, so a nicely designed two-column resume can show up on the recruiter’s end with the skills section merged into the middle of the work history.
- Icons instead of plain text for contact details– A small phone or email icon sometimes takes the actual number or address down with it when the parser can’t read the image.
- Headers and footers– These get ignored by some systems altogether, so anything critical, name, phone number, current title, needs to live in the main body, not tucked up top where it might not get picked up at all.
- Text boxes– Content dropped into a text box rather than the normal flow of the document is one of the more common reasons a resume comes through looking oddly incomplete.
What Tends to Work Instead
A clean, single-column layout with standard section titles (Experience, Education, Skills, Certifications) tends to parse the most reliably across different systems. It also happens to be easier for a human to skim in the fifteen or twenty seconds most recruiters spend on a first pass, so the same choice helps on both ends.
Keywords Matter, Just Not the Way Most Advice Suggests
The instinct to cram a resume with every possible keyword from a job description, sometimes literally in white text on a white background so it’s invisible to a human reader but supposedly visible to the software, is bad advice that has aged particularly badly. Modern parsers can detect hidden text, and getting caught doesn’t help an application, it flags it.
What actually works is more straightforward and considerably less sketchy: read the job description closely and mirror its language where it’s genuinely accurate to the candidate’s background. If a posting asks for experience with “customer relationship management software” and the resume only says “CRM,” spell both out somewhere in the document. If a role requires “accounts payable” experience, that phrase should appear if the candidate has actually done that work, rather than a close synonym that a human would understand but a keyword match might not catch. This isn’t about deception. It’s about using the same words the employer used, because that’s the plainest way to show the fit actually exists.
Tailoring a resume per application, even in small ways, beats sending one static version to everything. It takes more time, but it consistently produces better results than a single document trying to be everything to everyone.
The Content Still Has to Be Good
None of this matters much if the resume itself is thin once a person actually reads it. A document that survives parsing perfectly but says “responsible for various tasks” and “results-driven team player” isn’t going to move forward just because it was formatted correctly. Specific, quantified accomplishments (managed a $2M budget, reduced processing time by 30%, supervised a team of eleven) tell a hiring manager something a generic phrase never will.
Seniority level should shape the language too. A resume for a director-level role that reads like an entry-level job description undersells the candidate, and the reverse is just as noticeable. The goal of surviving the software was never the finish line. It was always to get a fair read from the person who makes the actual decision.
Where a Recruitment Partner Changes the Equation
A resume submitted cold through a company’s careers page still has to clear whatever process that employer has set up, ATS included. A resume submitted through a recruiter often follows a different path entirely, going directly to a hiring manager who already trusts the source. This is a big part of what job placement services in USA actually provide beyond the initial match: a direct line past the general applicant pool, along with feedback on how a resume reads before it ever gets submitted anywhere.
Top hiring agencies in USA working across specific sectors tend to know precisely what a given employer’s screening process looks like and what their hiring managers actually respond to, which is a different kind of insight than a generic resume template can offer. At Serene Info Solutions, this shows up in the day-to-day work of matching candidates to roles across technology, healthcare, banking and financial services, manufacturing, and supply chain, alongside a presence as a best recruitment agency in Kolkata serving employers and candidates on both sides of that market.
The Bottom Line
The fear driving a lot of resume advice, that an invisible algorithm is silently discarding most applications, is largely built on a number that was never real to begin with. The more accurate picture is less dramatic, and honestly more useful. Three things do far more for a resume’s chances than any keyword trick ever could:
- Format it cleanly enough that the system actually reads it the way it’s meant to be read.
- Use language that matches the role instead of generic filler.
- Make sure the substance holds up once an actual person looks at it.
Candidates who want a second opinion on how a resume is likely to perform, or who want to understand how a specific employer’s process actually works, are welcome to reach out to Serene Info Solutions. Support runs across industries and across both the US and Kolkata markets, with the goal of getting the right resume in front of the right person, not just past a piece of software.
Frequently Asked Questions
Q: Should a resume be submitted as a PDF or a Word document?
PDF works well for most systems out there, provided that it is actually a text-based PDF, not an image of text converted into a PDF format. Some old and cumbersome ATS systems parse Word documents better, but if the job posting says which format it wants, then just follow its instructions. Nothing is specified about the format? Use PDF, because at least it will appear exactly as it was intended to.
Q: Does resume length affect how well it parses?
Not really. Length is more of a human problem than a software one. Recruiters spend maybe fifteen seconds on a first pass, and a three-page resume padded with a decade-old internship buries the two lines that actually matter. One to two pages covers most people fine. Someone twenty years into a technical or executive career can reasonably run longer, since there’s simply more relevant ground to cover.
Q: Are online ATS resume checkers worth using before applying?
For catching the obvious stuff, sure, a missing section header, text trapped inside a table, that kind of thing. Where they start to oversell themselves is the tidy percentage score at the end. No outside tool can see inside a specific company’s actual hiring setup, so that number is worth treating as a rough gut check, not something to chase toward 100.
Q: If a recruiter submits my resume, does it skip the ATS entirely?
Usually not. Most agencies still run candidates through the employer’s own system like anyone else. What’s different is the context riding along with it. It is important for the applicant’s resume to be presented together with a phone call from an individual who is already familiar with the hiring manager as it will get noticed no matter what rank it holds in the hierarchy.
Q: Is it really necessary to customize a resume for every single application?
Not a full rewrite, no. But a few minutes spent moving the most relevant accomplishment up top and swapping in language the posting actually used tends to beat a single one-size-fits-all version by a wide margin. It’s an easy habit to skip when applying to a dozen jobs a week, and it’s also one of the more obvious tells to a recruiter when someone hasn’t bothered.
