Why Use a Resume Example?

A great resume example does two things: it shows you the structure and tone that works for your target role, and it gives you a starting point so you're not staring at a blank page. The examples on Pika are modelled on patterns we see in real high-performing resumes - they use strong action verbs, quantify achievements, and follow ATS-friendly formatting. You don't copy them verbatim. You use them as a scaffold and replace the content with your own experience.

Frequently Asked Questions

Are these resume examples free to use?

Yes. Every resume example on Pika Resume is free to view and use as inspiration. You can also import any example as a starting point in our resume builder and customise it for your own job application - at no cost.

What kinds of resume examples are available?

We have professional resume examples across 12+ categories including software engineer, nursing, sales, data analyst, medical assistant, engineering, server, high school, teen, no experience, law school, and federal. Each example was crafted to reflect real-world hiring expectations for that role.

Can I download these resume examples as PDF?

Yes. Open any example, click "Use this resume", and you can edit it in our builder and download the final version as a PDF.

Are these real resumes from real candidates?

Our examples are professionally crafted to reflect what successful resumes look like for each role. We never publish real candidate resumes - every example is original content modelled on the patterns we see in high-performing resumes.

How do I pick the right resume example for me?

Start by filtering for your target job title or industry. If you don't see your exact role, look at adjacent roles in the same field - the structure and bullet-point style usually transfer well. You can also filter by experience level (no experience, student, professional) to find examples that match where you are in your career.

What if my industry isn't listed?

Pick the closest available example as a starting structure, then use Pika's JD-tailoring tool to rewrite the bullet points and inject keywords specific to your target role. Most resume formats translate across industries - what changes is the content.
