The single highest-impact change you can make to your resume is improving your bullet points. Most candidates write responsibility lists; the ones who get interviews write achievement narratives.
The XYZ Formula
Google's former SVP of People Operations Laszlo Bock described the formula as: "Accomplished [X] as measured by [Y] by doing [Z]."
In practice: "Reduced API response time by 40% by implementing Redis caching across 12 microservices."
This format works because it tells the recruiter what you did, how much it mattered, and how you did it — in one sentence.
Quantify Everything You Can
Numbers beat vague language every time. If you led a team, say how many people. If you grew something, give the percentage. If you saved time, give the hours per week. If you have no numbers, estimate conservatively and be honest about it.
Action Verbs That Signal Impact
Weak: Responsible for, Helped with, Worked on
Strong: Engineered, Deployed, Reduced, Grew, Launched, Automated, Negotiated, Designed
ATS systems weight action verb strength as part of their scoring. CVAgent's analyzer flags weak verbs and suggests replacements.
One Bullet Per Achievement
Never cram two achievements into one bullet. Readers scan — they will miss the second half. Keep each bullet to one sentence, one metric, one story.
