Common Resume Mistakes (2026)
The 15 most common resume mistakes that get applications rejected — by ATS systems and by human recruiters — and exactly how to fix each one.
Using a two-column or table-based template
Fix: Switch to a single-column format. Most ATS systems can't parse multi-column layouts — skills and experience in a sidebar may be completely ignored.
Listing job duties instead of achievements
Fix: Rewrite every bullet to show impact: what you did + what changed because of it + a number where possible. See our resume achievement examples guide.
No keywords from the job description
Fix: Read the JD and add the tools, role titles, and domain terms mentioned in the requirements. Run an ATS check to see which keywords you're missing.
A vague or generic professional summary
Fix: Tailor your summary to each application. Mention the exact role, your primary tool or domain, and one quantified achievement. Avoid 'results-oriented professional.'
Listing every job you've ever had
Fix: Show only the last 10–12 years in detail. For older roles, summarize in one line or drop them if irrelevant to your current target.
No quantified results anywhere
Fix: Go through your bullets and add a number to at least half of them. 'Improved performance' becomes 'Improved API response time by 40%.'
Typos and grammatical errors
Fix: Run the resume through spell check, read it aloud, and have a second person review it. Errors on a resume signal carelessness — especially for roles requiring attention to detail.
Including a photo or personal details
Fix: Remove your photo, date of birth, marital status, and religion. These are not expected and can introduce bias or ATS parsing issues.
No LinkedIn or GitHub link
Fix: Add your LinkedIn URL to your contact section. For tech roles, a GitHub link is equally important — it's proof of your work.
An email address that looks unprofessional
Fix: Use firstname.lastname@gmail.com or a similar clean professional email. hotboi2005@yahoo.com will get you filtered at many companies.
Weak action verbs
Fix: Replace 'responsible for', 'helped', 'assisted' with strong verbs: Built, Led, Reduced, Increased, Designed, Automated, Shipped, Mentored.
Skills section with soft skills listed as primary skills
Fix: Remove 'Communication', 'Teamwork', and 'Leadership' from your skills list. Demonstrate these through your experience bullets. The skills section is for hard, verifiable skills.
Missing contact information or wrong email
Fix: Double-check: name, current email, current phone, city. Test your LinkedIn URL. Nothing kills a promising resume faster than an unreachable candidate.
Not tailoring the resume to the job
Fix: A generic resume sent to 50 companies works worse than a tailored resume sent to 10. Mirror the language from each job description — it improves both ATS score and human relevance.
Resume too long (3 pages) or too short (half a page)
Fix: Aim for 1 page (under 7 years exp) or 2 pages (7+ years). Cut filler; add substance. A half-page resume suggests you have nothing to say.

FAQ
Why is my resume getting rejected even when I'm qualified?
The most common reasons qualified candidates get rejected: (1) ATS incompatible formatting (tables, columns, graphics), (2) missing keywords from the job description, (3) generic summary that doesn't match the role, (4) duty-based bullets without results, (5) no tailoring to the specific job. Fix these and your callback rate should improve significantly.
What is the biggest resume mistake?
Using a template with columns, tables, or text boxes is the single most costly mistake for ATS-screened roles — it can cause your entire resume to be unparseable. The second biggest: listing job duties instead of achievements. Duty lists tell recruiters what you were supposed to do; achievements show what you actually delivered.
Should I include hobbies on my resume?
Generally no. Hobbies take up valuable space without adding value for most professional roles. The exception: if a hobby is directly relevant (e.g., a gaming developer who builds indie games) or shows an impressive achievement (national-level sports, published writing). Casual hobbies like 'reading' or 'traveling' do nothing for your application.
Is it a mistake to have a photo on your resume?
In most countries (US, UK, India for tech roles) — yes. Photos introduce unconscious bias and are not expected. The exception: some European countries, modeling, or acting roles where appearance is relevant. Check the norms for your target geography. For tech roles in India, no photo is the safer choice.
