Top 5 Resume Mistakes That Are Costing You Interviews (And How to Fix Them)

Resume mistakes I see every day

You've sent out 30 applications and haven't heard a thing. The issue might not be you—it might be your resume. As someone who's reviewed thousands of resumes and worked extensively with Applicant Tracking Systems (ATS),

I see the same mistakes again and again. Here are 5 resume errors that could be killing your chances—and exactly how to fix them.

Mistake #1: Your Resume Isn’t ATS-Friendly

What’s the problem?

What to do instead: Use a clean, text-based format Mirror keywords from the job description Avoid images, tables, and columns Pro Tip: Save your resume as a .docx or PDF (only if the job posting allows PDFs).s

Mistake #2: Generic Summaries

“Motivated professional seeking a challenging role...” = red flag. Solution: Write a custom, results-focused headline tailored to the job.

Mistake #3: Too Much Fluff, Not Enough Results

Bullet points like “responsible for customer service” are vague.

Solution: Use numbers, achievements, or outcomes—“Resolved 50+ tickets per week with 95% satisfaction.”

Mistake #4: It Looks Like a Novel

Dense paragraphs = hiring manager fatigue.

Solution: Use white space, bullets, and headers to improve readability.

Mistake #5: It’s Not Focused

One-size-fits-all resumes get tossed.

Solution: Tailor your resume to the job description. One resume per role type.
