Why Avoiding the Top 10 Mistakes People Make on Their Resumes Matters

Small resume errors create big problems. ATS software automatically filters out resumes with formatting issues or missing keywords. Hiring managers form instant judgments based on typos and unprofessional presentation.

According to SHRM, the cost of a bad hire can reach 30–40% of an employee's first-year salary, underscoring why a precise resume matters.

These mistakes don't just cost you one interview. They stall your entire career progression. But here's the good news: most resume problems are easy to fix once you know what to look for.

Costly hiring mistakes can amount to 30–40% of an employee's annual salary, meaning a flawed resume not only stalls careers but also wastes employers thousands of dollars.

Mistake 1: Spelling and Grammatical Errors

Typos destroy your credibility instantly. Common mistakes include "recieved" instead of "received," mixing past and present tense, and misplaced apostrophes.

Fix this by reading your resume aloud. Use Grammarly or similar tools. Ask someone else to proofread it. Job seekers with over 99% accurate spelling are 3x more likely to be hired.

Mistake 2: Using a Generic Objective Statement

Objectives like "Seeking a challenging position where I can grow" tell employers nothing about what you offer them. They focus on what you want, not what you bring.

Replace objectives with professional summaries. Instead of "Seeking marketing opportunities," write "Marketing specialist with 5 years driving 40% revenue growth through digital campaigns." Research the company and use specific keywords from their job posting.

Mistake 3: Poor Formatting and Layout Choices

According to Jobscan, 99.7% of recruiters use ATS software that can't parse complex formatting. Discover the AI-driven tools we use to vet candidate resumes on our Tools We Use page.

Inconsistent fonts, cramped text, and unclear headings make your resume hard to scan. Hiring managers need to find information quickly.

Use one-inch margins, consistent font sizes, and clear bullet point hierarchy. Stick to standard fonts like Arial or Calibri. Keep formatting simple and professional.

Mistake 4: Listing Outdated or Irrelevant Experiences

Including that part-time retail job from 15 years ago dilutes your professional impact. Irrelevant experience takes up valuable space and confuses your career narrative.

Focus on your 3-5 most recent, relevant roles. Trim unrelated content to maintain a one- to two-page length. The average resume length for 2024 was 1.7 pages, and 70% of hiring managers prioritize two-page resumes.

Mistake 5: Ignoring Applicant Tracking System (ATS) Keywords

ATS software scans for role-specific terms before human eyes see your resume. Missing keywords leads to automatic rejection.

Study the job description and weave relevant keywords naturally into your experience. If they want "project management," use that exact phrase. Don't just say "led projects." Up to 90% of employers use ATS to manage applications.

Mistake 6: Making Your Resume Too Long or Too Vague

Finding the right balance between comprehensive and concise creates the biggest challenge. Two-page resumes make up 47% of submissions, while 88% of recruiters expect senior professionals to submit resumes longer than one page.

Keep your resume to one page if you're early in your career, two pages for senior roles. Use concise bullet points that emphasize achievements. Remove redundant phrases like "responsible for" or "duties included." Focus on impact, not tasks. Each bullet point should demonstrate value.

Mistake 7: Using Unprofessional Contact Information

Email addresses like "partygirl2000@email.com" or missing LinkedIn profiles signal unprofessionalism. Incomplete contact information means missed opportunities.

Use a professional email format: firstname.lastname@email.com. Include your phone number, city and state, and LinkedIn URL. Double-check that all links work and phone numbers are correct.

Mistake 8: Overusing Buzzwords and Clichés

Terms like "team player," "hard worker," and "results-driven" mean nothing without proof. They make your resume sound generic.

Replace clichés with concrete examples and strong action verbs. Instead of "team player," write "collaborated with 8-person team to deliver project 2 weeks ahead of schedule." Use verbs like "spearheaded," "optimized," and "achieved."

Mistake 9: Submitting the Wrong File Format

Overly styled PDFs or unusual formats can break ATS parsing. Your beautiful design becomes unreadable text soup.

Use simple PDF or .docx formats. Name your file clearly: First_Last_Resume.pdf. Avoid special characters or spaces in filenames. Test your resume by copying and pasting it into a plain text document to see how ATS reads it.

As Job Search Coach notes, .docx files often parse more reliably than PDFs—test yours by pasting into plain text.

Mistake 10: Failing to Quantify Achievements

Statements like "responsible for sales" tell employers nothing about your performance. Numbers prove your impact.

Transform duty-focused statements into metric-driven accomplishments. "Increased sales by 30%" beats "responsible for sales" every time. Include percentages, dollar amounts, time frames, and team sizes whenever possible.

Key Takeaways: Avoiding the Top 10 Mistakes People Make on Their Resumes

The core principles are simple: proofread thoroughly, tailor your content, use metrics, optimize for ATS, and maintain professional formatting. These small fixes create big interview gains.

Remember that your resume is a marketing document, not a life history. Every word should demonstrate value to potential employers.
