Your resume is your first impression. It's your foot in the door, your handshake before the interview, and your best shot at standing out in a crowded job market. But despite its importance, so many people unknowingly sabotage their own chances with simple, avoidable mistakes. Whether you're a recent graduate, a seasoned professional, or someone making a career pivot, these resume slip-ups can hold you back. Below, we'll break down five of the most common mistakes people make on their resumes, why they hurt your chances, and how to fix them.
This might be the biggest mistake out there. People often create one version of their resume and send it to every employer, regardless of the position or industry. It seems efficient, but it's also lazy and ineffective. Recruiters can smell a generic resume from a mile away.
Why it's a problem: Every job is different, even if the titles are similar. Employers want to know how your experience matches their specific needs. A generic resume fails to connect the dots.
The fix: Tailor your resume to each job you apply for. Yes, it takes more time, but the return is worth it. Start by carefully reading the job description. Highlight keywords and required skills, then reflect those in your resume. Adjust your summary, reorder bullet points, and emphasize the most relevant experiences.
Example: If you're applying for a project manager role in tech, highlight your tech experience and leadership on technical teams first. When applying for a healthcare project manager job, spotlight your understanding of regulations, patient privacy, or cross-functional team collaboration.
Too many resumes read like job descriptions: "Managed schedules," "Handled client communication," "Processed reports." Cool. But what did you actually achieve?
Why it's a problem: Listing responsibilities doesn't show impact. Hiring managers want to know what value you brought to the role, not just what you were supposed to do.
The fix: Focus on accomplishments, outcomes, and metrics. Use the STAR method: Situation, Task, Action, Result. Instead of saying, "Managed social media accounts," say, "Increased social media engagement by 65% over six months through targeted content strategy and daily interaction."
Quantify everything you can. Numbers catch the eye and prove your impact.
Example rewrite: Before: "Led team meetings and tracked project deadlines." After: "Improved project delivery time by 20% by implementing a streamlined task tracking system and leading weekly strategy meetings."
You may be proud of your high school achievements or that summer job you had ten years ago, but they might not belong on your resume anymore.
Why it's a problem: Recruiters skim resumes in seconds. Including irrelevant info clutters your document and distracts from what really matters. It can also make you seem unfocused or out of touch.
The fix: Stick to experience, skills, and education that's relevant to the job you're applying for. If you’re well into your career, you don’t need to list every job you’ve ever had. Focus on the last 10-15 years. Keep it sharp and tailored.
What to trim or remove:
-
High school info if you have a college degree
-
Outdated software or tools (no one cares about Windows 95 proficiency)
-
Unrelated jobs unless they showcase transferable skills
Bonus tip: Avoid listing hobbies unless they directly support your career goals or show leadership, teamwork, or dedication.
You might have amazing experience, but if your resume looks like it was built in 2002 or is a wall of text, it’s not getting read.
Why it's a problem: Recruiters look at each resume for about 6–8 seconds on average. If they can’t quickly find key info, they move on. Bad formatting hurts readability and makes you look less professional.
The fix: Keep it clean, simple, and scannable. Use clear headings, bullet points, and consistent spacing. Stick to modern fonts like Calibri, Arial, or Helvetica. One page for early career, two pages max for experienced professionals.
Avoid:
-
Using multiple fonts
-
Overly bright colors
-
Dense paragraphs
-
Clip art or flashy design unless you're in a creative field
Bonus: Use resume templates from trusted sites like Canva, Zety, or Microsoft Office. Make sure to save and send as a PDF so your formatting doesn’t get wrecked when opened.
You could be the perfect candidate, but if your resume doesn’t play nice with the software many companies use to filter resumes, you’re toast.
Why it's a problem: ATS software scans resumes for keywords and formatting. If yours is too fancy, image-based, or lacking keywords from the job posting, it may never make it to a human reader.
The fix: Use plain, readable formatting. Avoid tables, text boxes, or columns if possible. Make sure your resume includes relevant keywords from the job description.
How to do this:
-
Take note of specific tools, qualifications, and action verbs from the job ad
-
Incorporate those naturally into your resume
-
Use standard section headings like "Experience," "Skills," and "Education"
Pro tip: Test your resume by copying and pasting it into a plain text document. If it looks jumbled or unreadable, the ATS might have the same problem.
Writing a strong resume isn't about tricking the system or cramming in every detail from your work history. It's about presenting your most relevant strengths in the clearest, most impactful way. Think of your resume like an ad for yourself. What’s going to grab attention, show value, and get someone to want to learn more?
Avoiding these five mistakes can make a big difference. Customizing each application, focusing on accomplishments, trimming the fat, improving readability, and optimizing for ATS aren't just resume hacks—they're essential steps to actually getting interviews.
And remember: a good resume gets you noticed, but a great one gets you in the room. Take the time to get yours right. It’s worth it.
