TL;DR: Most rejections come from small, fixable mistakes: outdated personal details, duties instead of results, layouts ATS can’t read, and generic text that isn’t tailored to the job. Go through this list once before every application.
Nobody tells you why your resume was rejected. Here are the mistakes that most often cost people a callback, grouped so you can check yours quickly.
Personal details and format
- Date of birth, father’s name, religion or marital status (biodata details)
- Full postal address (city is enough)
- Unprofessional email address
- “RESUME” written at the top instead of your name
- A photo where it isn’t expected
- A declaration at the end (“I hereby declare…”)
- Two or more pages with under 5 years of experience
Summary and structure
- A generic career objective
- No summary at all for an experienced professional
- Important information buried at the bottom
- Inconsistent date formats
- Unexplained gaps
Experience and skills
- Duties instead of achievements (“Responsible for…”)
- No numbers anywhere
- Skills you can’t discuss in an interview
- A list of 40 tools with no evidence
- Soft-skill adjectives with no proof (“hardworking”, “team player”)
- Star ratings and skill bars
ATS and formatting
- Text inside images or icons
- Complex tables and text boxes
- Contact details only in the header
- Creative section names (“My journey”)
- Scanned PDFs with no text layer
Strategy
- The same resume for every job
- Keywords that don’t match the job description
- Overselling: claims you can’t back up in the interview
- Spelling and grammar mistakes
How to check yours in 10 minutes
- Run the copy-paste test: select all text in your PDF and paste it into Notepad. Jumbled text means the ATS sees a mess.
- On GoResume, the strength score shows which sections are missing, and Tailor shows which keywords from the job post you’re missing.

The 5 mistakes worth fixing first
If you only have 15 minutes, fix these, because they affect the most applications:
- Duties instead of achievements. Rewrite your top 3 bullets with numbers.
- One resume for every job. Tailor the summary and skills to the job post.
- Biodata details. Remove date of birth, father’s name, religion and the declaration.
- ATS-breaking layout. If the copy-paste test gives jumbled text, switch to a simple template.
- No summary. Add two lines: role, years, core skills, one proof.
Why small mistakes have big effects
Recruiters compare many similar resumes quickly. When two candidates look equally qualified, small signals decide who gets the call: a clear title, a number in the first bullet, a clean layout, no typos. None of these take long to fix, which is why they’re worth checking before every application.
