The short answer
The inconsistencies that cost interviews are dates that don't add up (impossible ranges, unexplained overlaps, mixed formats), titles that don't match the work or your level, claims your history doesn't support ("10+ years" with 4 years of jobs, a certification listed nowhere), and a resume that disagrees with your LinkedIn. Each one makes a reader question everything else, so check them before you apply.

Why small contradictions matter so much
Recruiters spend seconds on a first read. They aren't checking every fact, they're looking for reasons to trust or doubt the page. One date that ends before it starts, or a senior title with junior responsibilities, is enough to move a resume to the "no" pile, even when the rest is strong.
Most inconsistencies aren't lies. They come from editing an old resume, copying a template, or rounding numbers differently in two places. That's why a checklist helps.
1. Dates that don't add up
- A job that ends before it starts, or a past job that ends in the future.
- Two full-time jobs overlapping for months with no explanation.
- Mixed formats: "March 2021" in one place and "03/2021" in another.
- Education dates that clash with the career, like a senior role years before graduating.
- Unexplained gaps of more than six months.
2. Titles that don't match the work
A title sets expectations. If the bullets describe something else, or a different level, readers notice.
Marketing Intern · "Led a team of 25 engineers to rebuild the platform"
Marketing Intern · "Coordinated launch messaging with the 25-person engineering team"
3. Claims your history doesn't support
- Years of experience in the summary that the dates don't cover.
- A certification or degree mentioned in the summary but missing from Education or Certifications.
- The same result given two different numbers in two places.
- Core skills in the skills list that nothing in your experience shows.
"Data scientist with 12+ years of experience" (first job: 2021)
"Data scientist with 4 years of experience, after 6 years in retail analytics"
4. Headline and LinkedIn mismatches
Your headline should describe the level you hold or the role you're targeting honestly. "Senior Product Manager" at the top with "Product Manager" as your latest title looks inflated. And recruiters often open your LinkedIn: titles and dates that differ from your resume raise the same doubts as a mistake on the page.
5. Small inconsistencies that still show
- Past jobs written in the present tense, or the current job in the past tense.
- Some bullets ending with a period and others not.
- The same skill listed twice in different groups.
- A job title that changes spelling between the headline and the experience section.
Checklist
- Every date range is possible, in one format, newest first
- Overlaps and gaps are labelled or explained
- The years in your summary match your work history
- Your headline matches your latest title (or says you're changing careers)
- Every credential you mention is listed with its year
- Your resume and LinkedIn show the same titles and dates
