Ensure your resume strikes the right balance between confident and humble, professional yet personable.
Recruiters often skim a resume in seconds, and tone shapes their impression before they weigh the details. A resume can sound robotic and generic, overly modest or boastful, even when the experience behind it is strong.
Before: "Responsible for managing social media and helping with various marketing tasks." After: "Grew our Instagram audience from 4,000 to 15,000 in a year by launching a weekly video series." The second line replaces passive duty language with a specific, owned result, which reads as confident without sounding arrogant.
For more on each, see why your resume sounds robotic and how to sound confident, not arrogant. If you are writing a cover letter too, how to tell if your cover letter sounds desperate covers the most common traps.
Tone is one part of a strong application. The checker estimates how your writing is likely to read; it cannot guarantee interviews or replace tailoring your resume to each role.
