Resume Mistakes to Avoid: 12 Fixes With Before-and-After Examples
Most weak resumes are not weak because the person lacks experience. They are weak because of a handful of fixable habits: bullets that list duties, details that do not add up, layouts that fight the reader, and files sent in a state nobody checked. This article goes through twelve of them, shows a before-and-after for the ones where wording is the problem, and ends with a ten-minute check you can run on any resume before you send it.
Wording mistakes: when the content says less than you did
1. Bullets that describe the job instead of your work in it. A job description tells the reader what the role was supposed to involve. Your resume should tell them what happened because you were there. If a bullet would be equally true for anyone who held the same title, it is a duty, not an achievement.
Customer support executive
Responsible for handling customer queries via phone and email.
Handled 40–50 customer queries a day across phone and email; wrote 12 saved replies for the most common billing questions, which the team still uses.
The after version answers "how much?" and "what changed?". Use numbers you can explain in an interview, even rough ones, and never invent them.
2. Adjectives with no evidence behind them. "Hardworking, dynamic, result-oriented team player" appears on so many resumes that a reader skips it without noticing. Adjectives cannot be checked; examples can. Replace each adjective with the fact that made you want to use it.
Summary line
Dynamic and hardworking professional with excellent communication skills.
Accounts assistant with three years in GST filing and vendor reconciliation for a 200-employee manufacturer; trained two new joiners on Tally.
3. An objective that only says what you want. "Seeking a challenging position in a reputed organisation" tells the employer nothing about what you offer. A short summary of what you bring does the same job better. Our article on writing a resume summary or objective covers when each one makes sense.
4. The same resume for every application. Sending one version everywhere means the most relevant experience for each role may sit in the fifth bullet of the second job. Reordering bullets and adjusting the summary for each application is usually a fifteen-minute job; the method is in how to tailor your resume for each job.
Factual mistakes: details that make a reader doubt the rest
5. Dates that do not line up. Overlapping jobs with no explanation, a gap hidden by listing years only, or "2023 – Present" on a job you left last month all invite questions. Use month and year for every role, in one consistent format. If roles overlap because one was part-time or freelance, say so in the entry. If there is a gap, our guide to explaining a career gap has wording for the common reasons.
6. Contact details that are wrong, outdated or unprofessional. Check the phone number digit by digit. Use an email address made from your name rather than a nickname from school. Add your city and, if relevant, whether you are open to relocation. A full postal address is not needed for most applications.
7. Personal details carried over from a biodata. Many Indian resumes still include date of birth, father's name, religion, marital status, nationality, a list of languages with reading/writing/speaking ticks, and a closing "Declaration: I hereby declare that the above information is true…". For most private-sector jobs, none of this helps and all of it takes space from your experience. Leave it out unless the employer's format asks for it. The exception is applications with a prescribed format, such as many government and public-sector forms: follow their format exactly.
8. Inflated titles. Writing "Marketing Manager" when your offer letter said "Marketing Executive" can surface in a background check and undo an otherwise good application. If your responsibilities were bigger than your title, keep the real title and let the bullets show the scope.
Layout mistakes: when the design gets in the reader's way
9. Shrinking everything to force one page. Cutting the font to 8 or 9 points and the margins to almost nothing produces a page that is technically one page and practically unreadable. Cut content instead: old roles can shrink to one line, and duty-style bullets are the first to go. If you genuinely have more than one page of relevant experience, a second page is fine — see when a two-page resume is the right choice.
10. Skill ratings that do not mean anything. Bars, stars and dots ("Excel ●●●●○") look tidy but answer no question a recruiter has. Four out of five compared with whom? Some of our own templates include rating dots or bars because some users want them; if you pick one of those, consider replacing ratings with evidence ("Excel: pivot tables, XLOOKUP, monthly MIS reports") or switching to a template without them.
11. A photo where none was asked for. For most jobs in India, the US, the UK, Canada and Australia, a photo is not expected and takes space. Some roles and some countries do expect one; if the posting does not ask, leave it out. Several of our templates have a photo area — you can use those without uploading a photo, but a template designed without one usually looks better in that case.
Sending mistakes: the file itself
12. A file nobody checked in the form the employer receives it. Three things go wrong here more often than people expect:
- The file name. "resume_final_v3 (1).pdf" says something about how organised you are. Use your name and the role: "Priya-Sharma-Data-Analyst-Resume.pdf".
- Text that cannot be read as text. Some job portals read the text out of your uploaded file to pre-fill their forms. If you cannot select and copy the words in your PDF, that software cannot read them either. Test it: open the PDF, try to highlight a line, paste it into a notepad. The PDF download from our builder is image-based, which keeps the design exact but means the text is not selectable — so for portals that read uploads, also keep a text-based copy (for example, typed into a word processor and saved as PDF), or fill the portal's fields by hand.
- The wrong version. If you keep several tailored versions, open the attachment one last time before you press send.
The twelve mistakes at a glance
| Mistake | Why it hurts | Fix |
|---|---|---|
| Duty-list bullets | Reads like the job ad, not your work | Add scale and outcome to each bullet |
| Unproven adjectives | Skipped by readers; cannot be checked | Replace with the fact behind the adjective |
| "Seeking a challenging role" objective | Says what you want, not what you offer | Write a 2–3 line summary instead |
| One version for every job | Relevant work gets buried | Reorder bullets and summary per role |
| Inconsistent or overlapping dates | Raises questions you are not there to answer | Month + year everywhere; label part-time work |
| Wrong or unprofessional contact details | You cannot be reached, or look careless | Name-based email; check every digit |
| Biodata details (DOB, religion, declaration) | Uses space, adds nothing for most roles | Remove unless the employer's format asks |
| Inflated titles | Can fail a background check | Real title; show scope in bullets |
| Tiny font to fit one page | Hard to read | Cut content, not font size |
| Skill rating bars | Meaningless scale | Show how you used the skill |
| Unrequested photo | Takes space; not expected in most markets | Leave out unless asked |
| Unchecked file | Bad file name, unreadable text, wrong version | Rename, copy-test the text, open before sending |
A ten-minute check before you send
- Read only the first third of page one. Would someone who stopped there know what job you do and why you fit this role?
- Check every date, job title and company name against your offer or relieving letters.
- Call or message your own phone number from the resume if you have changed SIMs recently.
- Read each bullet and ask "so what happened?". Rewrite any bullet without an answer.
- Delete biodata-style details the employer did not ask for.
- Open the final PDF on your phone. Headings should still stand out; nothing should be cut off.
- Try to copy a line of text from the PDF. If it will not copy and you are uploading to a portal, prepare a text-based version.
- Rename the file with your name and the role.
Key takeaways
- Turn duties into results: say how much, how often, and what changed.
- Replace adjectives such as "hardworking" with the facts that prove them.
- Drop biodata details and the declaration unless the employer's format requires them.
- Cut content before you cut font size; a second page is acceptable when the experience justifies it.
- Test whether the text in your PDF can be copied before uploading it to a job portal.
Put this into practice
- Start from a plain, photo-free layout: the free Clean Professional template.
- Compare all layouts, including which ones have photo areas and rating bars, on the resume templates page.
- Working on the bullets themselves? See how to quantify your achievements.
Frequently asked questions
For most private-sector jobs, no. "I hereby declare that the above information is true" is a biodata convention and adds nothing a recruiter needs. Include it only when the employer's prescribed format asks for it, which is more common in government and public-sector applications.
Rarely on its own, but it makes the reader wonder what else was not checked, and in roles where accuracy matters it counts against you. Run a spell-check, then read the resume aloud slowly; reading aloud catches correctly spelled wrong words that spell-checkers miss.
Not in itself. Colour and a sidebar are fine when the content is strong and the layout is easy to scan. Be more careful in conservative fields such as law, banking and public sector, and when applying through portals that read your file, where a simple single-column layout with selectable text is the safer choice.
Roughly the last ten to fifteen years in detail. Older roles can be reduced to a single line with title, company and years, or dropped if they are unrelated to the work you are applying for now.
