FAQ
How do I write achievement-based resume bullets?
Use the STAR or CAR formula: Situation/Context, Action you took, Result achieved. Start with a strong action verb, describe what you did, and end with a measurable outcome. Example: 'Reduced database query time by 60% by introducing indexing strategy and query plan analysis.'
What if I don't have numbers to quantify my achievements?
Think about scale, frequency, or team impact. 'Maintained a reporting dashboard used by 50 stakeholders' or 'Automated a manual process that previously took 3 hours per week' are still achievements even without percentages. Always estimate conservatively — any specific number beats a vague claim.
What are the best action verbs for resume bullets?
Strong verbs include: Built, Led, Reduced, Increased, Designed, Launched, Migrated, Automated, Optimized, Delivered, Shipped, Mentored, Spearheaded, Overhauled. Weak verbs to avoid: Responsible for, Worked on, Helped with, Assisted in, Participated in.
How many bullet points should each job have?
3–5 bullets per role is ideal. For your most recent and relevant position, you can go up to 6. For older or less relevant jobs, 2–3 is enough. Each bullet should show distinct impact — don't pad with filler responsibilities.
