There’s a whole cottage industry built on ATS anxiety. Resume services love to tell you that applicant tracking systems are ruthlessly filtering out qualified candidates left and right, and that you need their $200 template to survive the robot apocalypse.
The truth? ATS systems are a lot simpler than most people think. Many of them just sort candidates by application date. Some do keyword matching. A few of the more sophisticated ones score relevance. But the idea that your resume is getting “silently rejected” because you used the wrong font? That’s mostly marketing.
That said, you can still shoot yourself in the foot with genuinely bad formatting. This guide covers what actually matters and what you can stop worrying about.
An ATS parses your resume into structured data: contact info, work history, skills, education. It then stores that data so recruiters can search and filter candidates. Some systems score you against the job description. Most just make it easier for recruiters to manage a large applicant pool.
The parsing part is where formatting matters. If the ATS can’t extract your information correctly, a recruiter might never see your full qualifications, even if they pull up your application.
But here’s what the resume-optimization industry doesn’t tell you: most modern ATS platforms (Greenhouse, Lever, Workday, iCIMS) handle standard formatting just fine. The days of needing to submit a bare-bones .txt file are long gone. The real risk isn’t using a serif font. It’s burying your experience in a layout the parser can’t follow.
Yes, 99% of Fortune 500 companies use an ATS. That stat gets thrown around a lot. What it really means is that your resume goes into a database, not that it gets automatically rejected. The ATS is a filing system, not a bouncer.
That said, 88% of employers have acknowledged that these systems can filter out qualified candidates due to formatting issues. So basic formatting hygiene matters. You don’t need to obsess over it, but you shouldn’t ignore it either.

The resume advice industry has turned ATS formatting into a much bigger deal than it needs to be. But there are a few things that genuinely confuse parsers:
Everything else, like font choice and bullet point style, matters much less than people think. Use a readable font. Use standard bullets. You’ll be fine.
You don’t need a special “ATS template.” You need a clean, readable resume. It turns out the same things that make a resume easy for software to parse also make it easy for a recruiter to skim during their six-second scan.
This is the format that works everywhere. List your most recent job first, work backward, and keep everything in one column. It’s easy to follow for both humans and software.
Two-column resumes are a gamble. Some modern ATS platforms handle them fine, but enough don’t that it’s not worth the risk. And honestly, side columns rarely add much. That sidebar with your skill ratings or a headshot? It’s not helping your candidacy.
Use a standard font (Arial, Calibri, Georgia, Times New Roman) at 10-12pt. Set margins between 0.5 and 1 inch. Use standard bullet points.
That’s it. You don’t need to overthink this part.
Label your sections clearly: Work Experience, Education, Skills, Professional Summary. An ATS looks for these standard labels to figure out where your work history ends and your education begins.
Don’t get creative here. “Where I’ve Been” and “My Professional Journey” might sound more interesting, but they make it harder for both parsers and humans to find what they’re looking for.
Here’s what a solid foundation looks like:
Your Name City, State | Phone Number | Email Address | LinkedIn Profile URL
Professional Summary
Data-driven Marketing Manager with 8+ years of experience developing campaigns for B2B SaaS companies. Built and executed SEO, content, and marketing automation programs that drove a 45% increase in qualified leads at my last company. Looking to bring that same approach to [Company Name].
Work Experience
Senior Project Manager | Tech Solutions Inc. | City, State | 01/2020 - Present
Nothing fancy. Single column, clear headings, quantified achievements. This format parses correctly on every ATS we’ve tested at Proficiently, and it’s easy for a recruiter to scan.
A clean layout gets your resume parsed correctly. Keywords determine how relevant you look once it’s in the system. But the way most people think about keywords is wrong.
The conventional advice is to mirror the exact phrasing from the job description. Pull out every keyword and jam it into your resume. This advice is based on how ATS systems worked five or ten years ago, when most did simple string matching.
Modern ATS platforms are smarter than that. Many use semantic matching, meaning they understand that “managed a team” and “led a cross-functional group” mean roughly the same thing. You don’t need to use the exact word from the job description to get credit for the skill.
At Proficiently, when we tailor resumes for specific roles, we focus on intent and meaning first. We make sure your experience maps to what the role requires. We do some keyword matching too, especially for technical skills and certifications where exact terms matter (Python is Python, not “a popular programming language”). But leading with achievements and letting the keywords follow naturally produces better results than stuffing keywords into awkward sentences.
Read the job description and identify two things:
Hard skills and tools — Technical skills, software, certifications, methodologies. These are worth matching closely because they’re often specific terms that recruiters search for. If the job asks for “Salesforce CRM” experience, say “Salesforce CRM,” not “CRM platform.”
The actual job — What does this role do day to day? What problems does it solve? Make sure your resume demonstrates experience doing those things, even if you describe them slightly differently.
Here’s a practical example. Say you’re applying for a Senior Data Analyst role and the job description mentions SQL, Python, Tableau, A/B testing, and “presenting findings to cross-functional stakeholders.”
Your resume should show that you’ve used those tools and done that kind of work:
Notice how the keywords appear naturally inside real accomplishments. That reads well to a human and parses well for software.
For more on this, our resume tailoring prompts walk through the process step by step.
Here’s a quick reference for the formatting decisions that actually matter:
| Element | Do this | Avoid this |
|---|---|---|
| Layout | Single column, top to bottom | Multiple columns, text boxes |
| Fonts | Arial, Calibri, Georgia, Times New Roman | Decorative or custom fonts |
| Headings | ”Work Experience,” “Skills,” “Education” | Creative labels like “My Journey” |
| Graphics | None in the resume body | Photos, logos, skill bars, charts |
| Contact info | In the main document body | In the header or footer |
| File type | PDF or .docx | Image-based files (.jpg, .png) |
A note on the file type debate: the old advice was to always submit .docx because PDFs could get parsed as images. That’s outdated. Modern ATS platforms handle PDFs without issues, and PDFs have the advantage of looking exactly the same on every computer. Submit whichever the application asks for. If it doesn’t specify, either is fine.
Before you submit, it’s worth checking that your resume parses correctly. But be careful about how you do this.
Most free ATS checkers are marketing funnels for resume-writing services. They’ll scan your resume, give you a scary low score, and then offer to fix it for $150. The scores are largely meaningless because every company’s ATS is configured differently.
What these tools are useful for is seeing the parsed text output: the raw text that an ATS extracts from your document. Look at that output and check:
If the parsed text looks reasonable, your formatting is fine. Don’t chase a perfect score.
No amount of ATS optimization helps if you’re applying to jobs you’re not qualified for, or if your resume doesn’t show relevant experience. We see this constantly at Proficiently: someone will spend hours tweaking their resume formatting when the real issue is that their resume doesn’t connect their experience to what the role requires.
If you’re applying to lots of jobs and not hearing back, the problem is usually the content of your resume, not the format.
This is where most ATS advice goes off the rails. The standard guidance is to tailor your resume for every single application, spending 10-15 minutes customizing it each time. That math doesn’t work when you’re applying to 50+ jobs over several months.
Here’s a more realistic approach: create a few targeted versions of your resume, one for each job title you’re pursuing. If you’re looking for both Product Manager and Program Manager roles, those need different resumes. But you don’t need a unique version for every Product Manager job at every company.
Put your energy into the cover letter and any application questions, where you can speak directly to the specific company and role. That’s where customization has the highest return.
That said, if you’re applying to a dream role at a company you really want, absolutely spend the time tailoring your resume to that specific job description. For the career-change resume, tailoring matters more too, because you need to translate your experience into the new field’s language.
The jobs where per-application tailoring makes the biggest difference are the ones where you’re a non-obvious fit. If your background maps cleanly to the role, a good base resume does most of the work. If you’re making a career pivot or your experience is adjacent but not identical, that’s where careful customization changes outcomes.
This is one of the things we built Proficiently’s resume tailoring to handle. We create targeted versions of your resume for each type of role you’re going after, and then fine-tune for individual applications when it makes a difference. You pick the jobs, we handle the resume work.
Either works. The old advice to always use .docx was based on older ATS platforms that struggled with PDFs. That’s no longer an issue with modern systems like Greenhouse, Lever, and Workday. Submit whatever the application requests. If it doesn’t specify, PDF is fine and has the benefit of consistent formatting across devices.
We’d recommend against it. Some modern ATS platforms handle columns correctly, but many still read straight across the page. There’s no way to know which system a company uses, so a single-column layout is the safer choice. Plus, columns usually don’t add information density. They just make things harder to scan.
Embed them in your accomplishments instead of listing them in isolation. Rather than just writing “Agile Methodologies” in a skills list, write: “Led a cross-functional team using Agile project management to deliver the product 15% under budget.” The keyword is there, and it’s backed by a result.
Not really. ATS “scores” from online checkers don’t correspond to how actual company ATS systems evaluate your resume. Focus on clean formatting and making sure your experience clearly maps to the kinds of roles you want. If your resume format is causing issues, our ATS fix prompts can help you clean it up quickly.
Tired of formatting and tailoring resumes for every application? At Proficiently, we handle it. You tell us what roles you’re targeting, pick the jobs you want to apply to, and we tailor your resume and submit the application. See how it works.
