Common Resume Mistakes to Avoid (2026)

Most resumes are rejected for avoidable reasons, not a lack of qualifications. A typo, a vague bullet, or a layout the applicant tracking system cannot read will quietly knock out a strong candidate before a human ever weighs in.

Here are the mistakes that cost interviews most often — and how to fix each one.

Content mistakes

• Listing duties instead of achievements — "responsible for X" tells the reader nothing about your impact.
• No numbers: quantify results with percentages, dollars, time saved, or scale.
• A generic resume sent to every job instead of tailoring to the posting.
• A vague objective ("seeking a challenging role") in place of a focused summary.
• Weak, repetitive openers like "helped", "worked on", and "responsible for".

Formatting and ATS mistakes

• Tables, columns, text boxes, and graphics that applicant tracking systems cannot parse.
• Non-standard section headings the ATS does not recognize.
• Putting key details in the header or footer, where many parsers ignore them.
• Saving as an image or scanned PDF instead of a text-based file.
• Cramming everything into a tiny font to force it onto one page.

Polish and presentation mistakes

• Typos and grammar errors — proofread, and have someone else read it too.
• An unprofessional email address; use a simple name-based one.
• Inconsistent formatting: mixed date styles, fonts, or bullet shapes.
• Outdated or irrelevant details like a photo (in the US), age, or marital status.
• A resume that runs longer than it needs to for your experience level.

A quick pre-send checklist

• Every bullet leads with an action verb and includes a result where possible.
• The resume is tailored to this specific job description.
• The layout is a single column with standard headings and a common font.
• There are zero typos and formatting is consistent throughout.
• Length matches your experience — one page for most, two if it is earned.
