Building a coding portfolio: 12 projects to impress interviewers

Meta has thousands of job openings every year and each opening receives hundreds —sometimes thousands — of applications. That’s a lot to sift through. Take it from me, I’ve been on the other side as an interviewer at Meta and beyond, and reviewing countless resumes gets mind-numbing.

In fact, at some point, I don't care what libraries or keywords I see on your resume. I go straight to your coding portfolio to see the hard proof of what you can actually DO with your skills.

In a crowd of candidates with similar qualifications, your portfolio is a demonstration of your problem-solving skills, initiatives, and interests.

In this guide, I’ll walk you through how to craft a coding portfolio that isn't just seen — it's top of mind. Whether you're an experienced engineer or just getting started, these tip will help you stand out and land the job you're aiming for.

Why a coding portfolio matters#

A coding portfolio is one of your biggest assets as a candidate.

Here's why:

1. Showing instead of telling: Demonstrate how you can apply your knowledge to real-world problems.

3. Shows commitment: Demonstrates your dedication and passion for coding.

4. Differentiates you from others: Helps you stand out in a pool of candidates with similar qualifications.

Key components of a strong coding portfolio#

When I evaluate a candidate's portfolio, I look for 6 qualifiers:

1. Diverse project selection: Include a variety of projects to demonstrate a broad skill set.

2. Quality over quantity: Focus on the quality and completeness of each project.

3. Detailed documentation: Provide clear documentation and explanations for each project.

4. Source code accessibility: Make your code available on platforms like GitHub.

5. User interface and user experience: Ensure your projects are user-friendly and visually appealing.

6. Problem-solving projects: Highlight projects that solve specific problems or improve existing solutions.
