Your resume is often your first impression with potential employers. Yet, many job seekers make avoidable mistakes that can cost them opportunities. In 2025, with hiring processes becoming more digital and competitive, avoiding these common pitfalls is essential. Here are the top resume mistakes and how to fix them.

1. Using a Generic Resume

The Mistake: Sending the same resume to multiple job applications without tailoring it to each role.

The Fix: Customize your resume for each job by incorporating relevant keywords, skills, and accomplishments that align with the specific role. Carefully review job descriptions and mirror the language used to ensure your resume passes applicant tracking systems (ATS).

2. Focusing on Responsibilities Instead of Achievements

The Mistake: Listing job duties instead of showcasing measurable results.

The Fix: Use the CAR (Challenge, Action, Result) or STAR (Situation, Task, Action, Result) method to highlight achievements with quantifiable outcomes.

Example:

M

Managed clinical trials for a pharmaceutical company.

Led Phase III trials for an oncology drug, accelerating FDA approval by 6 months and reducing trial costs by 15%.

3. Poor Formatting and Readability

The Mistake: Overly complex layouts, small fonts, or cluttered designs that make it hard to read.

The Fix: Keep formatting clean and ATS-friendly:

  • Use standard fonts like Arial, Calibri, or Times New Roman.
  • Keep section headings clear and bold.
  • Use bullet points instead of long paragraphs.
  • Save your resume as a Word document or PDF to maintain formatting integrity.

4. Overloading with Buzzwords and Jargon

The Mistake: Using vague phrases like “results-oriented leader” without evidence to back them up.

The Fix: Be specific and show proof of your skills with examples.

Example:

M

Innovative thinker with a proven track record of success in regulatory affairs.

Spearheaded regulatory submissions, leading to FDA and EMA approvals for two first-in-class biologics.

5. Including Irrelevant or Outdated Information

The Mistake: Listing early-career roles or irrelevant job experiences.

The Fix: Focus on the past 10-15 years of experience and highlight only relevant positions. Remove outdated technologies, skills, or coursework unless still applicable.

6. Not Showcasing Key Skills Effectively

The Mistake: Burying key skills in job descriptions rather than listing them clearly.

The Fix: Create a dedicated skills section that highlights industry-specific and transferable skills.

Example for Life Sciences roles:

  • Clinical Operations: Managed global Phase II and III trials.
  • Regulatory Compliance: FDA, EMA, and Health Canada submissions.
  • Biostatistics & Data Analysis: Expertise in SAS, R, and Python.

7. Missing Keywords for Applicant Tracking Systems (ATS)

The Mistake: Failing to use the right keywords from the job description, causing your resume to be overlooked by ATS software.

The Fix: Identify key phrases in job postings and incorporate them naturally throughout your resume, especially in the skills and experience sections.

8. Lack of a Strong Personal Branding Statement

The Mistake: Starting with a generic objective statement that doesn’t add value.

The Fix: Replace it with a compelling Personal Branding Statement that summarizes your expertise and impact.

Example:

M

Seeking a challenging role in clinical research.

Clinical Research Leader with 10+ years of experience in oncology and rare disease trials, accelerating drug development through innovative trial designs and regulatory strategies.

9. Not Including a LinkedIn Profile

The Mistake: Omitting your LinkedIn URL, making it harder for recruiters to find more details about you.

The Fix: Add a custom LinkedIn URL (e.g., linkedin.com/in/yourname) at the top of your resume. Ensure your profile aligns with your resume content.

10. Typos and Grammatical Errors

The Mistake: Submitting a resume with spelling mistakes or inconsistent formatting.

The Fix: Proofread thoroughly, use tools like Grammarly, and ask a colleague or mentor to review your resume before submitting.

Final Thoughts

Avoiding these common resume mistakes will significantly increase your chances of landing interviews. A well-structured, accomplishment-driven, and tailored resume makes a strong first impression and helps you stand out in today’s competitive job market.
