Resume Mistakes That Get You Rejected in 10 Seconds

Share on:

Recruiters spend 6–10 seconds scanning a resume before deciding whether to shortlist or reject it. In today’s competitive job market, especially in India, even small mistakes can cost you interviews.

Many qualified candidates get rejected—not because they lack skills—but because their resume fails to communicate value clearly.

In this guide, we’ll break down the most common resume mistakes in 2026, explain why they lead to rejection, and show you how to fix them.

If you’re serious about getting shortlisted, read this carefully.

1. Using a Generic Resume for Every Job

One of the biggest mistakes candidates make is sending the same resume for every role.

Why it gets rejected:

  • Doesn’t match job description
  • Lacks relevant keywords
  • Fails ATS screening

Fix:

✔ Customize resume for each job
✔ Add job-specific keywords
✔ Highlight relevant achievements

2. Resume Not ATS-Friendly

Most companies use Applicant Tracking Systems (ATS).

If your resume:

  • Has too many graphics
  • Uses tables improperly
  • Has images
  • Uses fancy fonts

It may never reach a human recruiter.

Fix:

✔ Use simple formatting
✔ Standard fonts (Calibri, Arial)
✔ Clear headings
✔ Save in PDF (if allowed)

3. Too Long or Too Short Resume

Common Problems:

  • 4–5 pages for 3 years of experience
  • 1-page resume with no meaningful content

Ideal Length:

  • Freshers: 1 page
  • 3–10 years experience: 1–2 pages

Recruiters don’t read stories—they scan impact.

4. No Quantified Achievements

Saying:

  • Responsible for sales

Is weak.

Saying:

  • Increased sales by 32% in 6 months

Is powerful.

Why it matters:

Numbers build credibility.

Fix:

Add:

  • Percentages
  • Revenue figures
  • Growth metrics
  • Timeframes

5. Poor Professional Summary

Your summary is the first thing recruiters read.

Weak summary example:

Hardworking and dedicated individual seeking opportunity.

Strong summary example:

Results-driven Sales Manager with 6+ years experience in B2B industrial sales, generating ₹5Cr annual revenue.

6. Irrelevant Information

Including:

  • Hobbies unrelated to job
  • 10th standard marks (after experience)
  • Personal details like siblings, etc

Recruiters don’t need this.

Remove:

  • Religion
  • Aadhaar number
  • Family details
  • Passport Number
  • Salary expectations (unless asked)

7. Spelling & Grammar Errors

One typo can create a bad impression.

Recruiters assume:
If you can’t proofread your resume, how will you handle client communication?

Fix:

✔ Use Grammarly
✔ Read aloud once
✔ Ask someone to review

8. No Clear Job Title or Career Direction

If your resume doesn’t clearly show:

  • What role you want
  • What industry you belong to

Recruiters get confused.

Confused resume = rejected resume.

9. Weak LinkedIn Profile or No Online Presence

In 2026, recruiters check LinkedIn immediately.

If:

  • Your profile is incomplete
  • Experience doesn’t match resume
  • No profile photo

It reduces credibility.

10. Using an Unprofessional Email ID

Emails like:

Create a poor first impression.

Use:
firstname.lastname@gmail.com

When scanning resumes, recruiters check:

If these are not clear instantly → rejection.
