Before & After: Resume Transformations

See how small changes can dramatically improve your resume's effectiveness

Generic Job Description vs. Achievement-Focused Bullet

Before:

"Responsible for managing a team of sales representatives and handling customer accounts."

After:

"Led a team of 6 sales representatives that exceeded quarterly targets by 28%, while improving customer retention rate from 76% to 94% through personalized account management."

Why It Works:

The correction quantifies the achievement (28% above targets, 18% improvement in retention) and specifies the team size while using a strong action verb (Led).

Vague Skill Statement vs. Specific Example

Before:

"Excellent communication skills and attention to detail."

After:

"Leveraged strong communication skills to negotiate vendor contracts, reducing supply costs by 15% while maintaining quality standards through detailed specification analysis."

Why It Works:

Rather than claiming skills, the correction demonstrates them through a specific achievement with measurable results (15% cost reduction).

Poor Job Title vs. Clarified Title

Before:

"Team Member, XYZ Company (2018-2020)"

After:

"Marketing Analyst (promoted from Marketing Assistant), XYZ Company (May 2018-December 2020)"

Why It Works:

The correction provides a specific, professional title, shows career progression, and includes precise dates rather than just years.

Duties-Focused vs. Results-Focused

Before:

"Updated company website content and managed social media accounts."

After:

"Increased web traffic by 43% by implementing SEO best practices and grew social media following by 10,000+ followers across platforms through targeted content strategy."

Why It Works:

The correction focuses on the measurable outcomes (43% traffic increase, 10,000+ followers) rather than just listing tasks performed.

Technical Skills List vs. Applied Skills

Before:

"Proficient in Python, SQL, Excel, and data visualization."

After:

"Applied Python and SQL to automate data pipeline that reduced reporting time from 40 hours to 4 hours monthly; created interactive Excel dashboards that visualized KPIs for C-suite decision-making."

Why It Works:

The correction shows how the technical skills were applied to solve specific problems and deliver tangible benefits (90% time reduction, executive decision support).

ATS Killer Mistakes

Errors that prevent your resume from passing Applicant Tracking Systems

Why ATS Compatibility Matters

Applicant Tracking Systems (ATS) are software used by 99% of Fortune 500 companies and 75% of smaller employers to screen resumes before a human sees them. These systems reject 75% of applications automatically, often due to simple formatting or keyword issues that can be easily fixed.

Complex Formatting

ATS cannot parse information in tables, columns, headers/footers, or text boxes

Fix: Use a single-column layout with standard sections and simple formatting

Non-Standard Section Headings

ATS may not recognize custom headings like 'Professional Journey' instead of 'Experience'

Fix: Use conventional section titles: 'Experience', 'Education', 'Skills', 'Certifications'

Image-Based or Graphics-Heavy Content

ATS cannot read text embedded in images or graphics

Fix: Ensure all information is in text format, not in images, logos, or infographics

Missing Keywords from Job Description

ATS ranks resumes based on keyword matches with the job posting

Fix: Incorporate key terms from the job description naturally throughout your resume

Incompatible File Format

Some ATS struggle with certain file types or PDFs with security settings

Fix: Submit as .docx or simple PDF; ensure PDF is text-based, not scanned

Special Characters and Symbols

Special characters can appear as garbled text in ATS systems

Fix: Stick to standard characters; avoid bullets like ✓ ► in favor of standard round bullets

Formatting & Design Mistakes

Visual and structural errors that make your resume difficult to read or unprofessional

Inconsistent Formatting

Using different fonts, spacing, bullet styles, or alignments throughout your resume.

58% of recruiters reject resumes with inconsistent formatting.

Common Examples:

  • Using Arial in one section and Times New Roman in another

  • Inconsistent spacing between sections
  • Some job titles in bold, others in italics

How to Fix It:

  • Choose one font family for the entire document
  • Standardize spacing between all sections
  • Use consistent bullet points throughout
  • Create a style guide for your resume with standard formatting for headings, text, and emphasis

Poor Readability

Making your resume difficult to scan quickly with tiny fonts, dense text blocks, or minimal white space.

Impact:

Recruiters spend an average of just 6-7 seconds scanning a resume initially. Poor readability means your qualifications get overlooked.

Rejection Factor:

75% of resumes are rejected due to readability issues.

Common Examples:

  • Font size smaller than 10pt
  • Margins less than 0.5 inches
  • Large blocks of text without breaks

  • Maintain margins of 0.5-1 inch on all sides
  • Break text into bullets and short paragraphs
  • Create clear visual hierarchy with consistent headers
  • Use white background with dark text for maximum contrast

Overdesigned Resume

Using excessive graphics, colors, or non-standard layouts that distract from content.

Common Examples:

  • Multiple bright colors throughout the document
  • Decorative fonts that are hard to read
  • Graphics or images that dominate the page

  • Ensure all information is in text format, not embedded in graphics
  • Use simple layouts that read top-to-bottom
  • Reserve creative designs only for creative industry applications

Inappropriate Length

Resume that's either too long (3+ pages for most positions) or too short (less than 1 full page).

Impact:

Excessively long resumes aren't read fully; too-short resumes suggest insufficient experience.

Rejection Factor:

46% of recruiters reject resumes longer than 2 pages for non-executive roles.

Common Examples:

  • Fresh graduate with a 3-page resume
  • 10+ years of experience condensed to half a page

How to Fix It:

  • 1 page for early career (0-10 years experience)
  • 1-2 pages for mid-career professionals
  • 2 pages maximum for most senior roles (except academic CV)
  • Focus on achievements rather than responsibilities to save space
  • Remove outdated experiences (>15 years old) unless particularly relevant

Content & Language Mistakes

Problems with the substance and wording of your resume

Generic, Non-Tailored Content

Common Examples:

  • Vague objective statement like 'Seeking a challenging position'

How to Fix It:

  • Have someone else proofread your resume
  • Use past tense for previous jobs, present tense for current position
  • Review multiple times on different days with fresh eyes

Expert Resume Advice

Insights from hiring professionals on avoiding common resume pitfalls

A

Amanda Chen

Senior HR Manager at Fortune 500 Company

"For each bullet point on your resume, ask yourself: 'So what?' If you can't clearly explain why that point matters for the target role, either rewrite it to show its relevance or remove it entirely."

M

Marcus Washington

Technical Recruiter with 15+ years experience

"The tech stack buzzwords matter, but don't forget to balance them with results. I need to know not just that you used Python or AWS, but what business problem you solved with it and what measurable outcome you achieved."

D

Dr. Sarah Wong

Career Counselor and Former Corporate Recruiter

"Have multiple people review your resume, but be strategic about whom you ask. Someone in your target industry can evaluate relevance, while someone from a different field can check if your achievements make sense to a general audience."

Frequently Asked Questions

What are the most critical resume mistakes that will get me automatically rejected?

The most immediate rejection triggers are spelling/grammar errors, unprofessional email addresses, missing contact information, and obvious lies or exaggerations. Additionally, resumes with formatting issues that prevent ATS systems from parsing them properly will be eliminated before a human even sees them. These include complex layouts with tables, text boxes, headers/footers with important information, and non-standard file formats.

How do I know if my resume is ATS-compatible?

To ensure your resume is ATS-compatible, use a simple, single-column layout without tables, text boxes, or headers/footers containing important information. Stick to standard section headings like "Experience" and "Education." Save in .docx or standard PDF format (not scanned PDFs). Use standard bullets rather than special characters, and include keywords from the job description. For a definitive check, use our free ATS compatibility tool that will scan your resume and identify potential issues.

Should I include a photo on my resume?

In the United States, Canada, UK, and Australia, photos on resumes are generally discouraged and can actually harm your chances. This is because they can lead to unconscious bias and potential discrimination concerns. Many companies automatically reject resumes with photos to avoid legal issues related to discrimination. However, in some European countries, parts of Asia, and the Middle East, photos are common and sometimes expected. Research the specific norms for the country and industry where you're applying.

How do I explain employment gaps on my resume?

Instead of trying to hide gaps (which can appear deceptive), address them strategically. First, use a month/year format for employment dates to avoid drawing attention to short gaps. For longer gaps, consider what you did during that time that might add value—education, freelance work, consulting, volunteer experience, or professional development. Include these activities on your resume if relevant. For significant gaps due to personal reasons (health, caregiving, etc.), you don't need to detail these on your resume, but be prepared to briefly address them positively in interviews, focusing on what you learned or how you stayed current in your field.

How do I make my resume stand out without making formatting mistakes?

The best way to make your resume stand out is through compelling content, not elaborate design (especially in non-creative fields). Focus on quantified achievements rather than job duties, use strong action verbs, and customize content for each position. For subtle visual distinction without ATS problems, consider using modest color for section headings, strategic bold or italic formatting for important accomplishments, and clean, consistent spacing with adequate white space. In creative fields, consider having two versions: an ATS-friendly version for online applications and a more designed version for direct emails or in-person networking.
