The difference between a resume that gets callbacks and one that doesn't usually comes down to one thing: specificity. Generic responsibilities are easy to write and easy to ignore. Specific outcomes with numbers are rare and memorable.
Below are resume examples across five major role categories. For each one, you'll see actual bullet points — both weak and strong versions — so you can see exactly what the difference looks like and apply the same pattern to your own experience.
The Universal Bullet Point Formula
[Action verb] + [what you did] + [for whom / at what scale] + [measurable result]
Not every bullet needs all four parts. But every bullet needs at minimum: an action verb + a result. If you can't name a result, name the scale. If you can't name the scale, name the context that makes the action valuable. Never write a bullet that's purely a responsibility description.

Entry-Level / Recent Graduate Resume Examples
Entry-Level / New Grad
When you don't have 5 years of experience, focus on: internships, academic projects, freelance work, and club leadership. Use the same impact formula — just at smaller scale.

How to handle limited experience
Put your education section near the top (just below contact info). Include GPA only if it's 3.5+ or if it's explicitly valued by the role. List coursework that's directly relevant to the job. Include a Projects section with 2-4 items — each one should have a link to GitHub, a live demo, or a description of what it does and what you built it with.
Use AI to generate strong bullets from weak descriptions: In resumeZero, paste a rough description of what you did into any experience section. The AI Tailor tool can rewrite it into a strong impact-focused bullet with the right structure and language for the job you're targeting.

Frequently Asked Questions
How many bullet points should each job have?
3-5 bullet points for your most recent/relevant roles, 2-3 for older roles. Quality over quantity — 3 excellent impact bullets are better than 6 mediocre ones. For jobs more than 8 years ago, 1-2 bullets or just a title and date is fine.
Should I use a resume objective or summary?
Summary (2-3 sentences describing your experience and value) beats objective (a statement of what you want from the employer) in every situation. Never use an objective statement for roles requiring any experience — it signals inexperience in resume writing.
How do I write resume bullets when I don't know the exact metrics?
Use reasonable estimates and note them as such: "reduced time by approximately 30%", "supported a team of roughly 20 engineers." If you genuinely don't have any metric, describe the scope and context: "Led the complete migration of the customer billing system, affecting all 4,000 enterprise accounts." Scope is better than nothing.
