Frequently asked questions
What is ATS resume optimization?+
ATS (Applicant Tracking System) optimization means formatting and writing your resume so it parses correctly through automated screening software before a recruiter sees it. This includes using single-column layouts, matching exact keywords from the job description, and structuring bullet points with quantified impact statements.
Do I need a different resume for every job application?+
Yes, for competitive roles. Generic resumes score lower in ATS systems because they do not match the specific keywords, level signals, and scope language in the target job description. Tailoring does not mean rewriting, it means adjusting 4-6 bullets and aligning your skills section to the specific posting.
What resume format beats most ATS systems?+
Single-column, reverse-chronological, plain font (no tables, no text boxes), saved as PDF. Two-column layouts and graphics cause parsers to drop entire sections. Stick to standard section headers: Work Experience, Education, Skills.
How many keywords should a resume have?+
Enough to match the job description naturally, not stuffed. A good benchmark is 70-80% keyword overlap with the key skills and responsibilities listed in the JD. More than that reads as keyword stuffing to both the ATS and the human reviewer.
What is the difference between a resume and a CV?+
A resume is a 1-2 page targeted document for a specific role, standard in the US, Canada, and most private-sector hiring. A CV (curriculum vitae) is a complete academic or professional record with no page limit, used in academic, medical, and international job markets.
