Both are valuable. Real-world data demonstrates lab/analytical prowess; simulations highlight computational skills. If you can combine both—excellent!

Q3: How do I handle proprietary or confidential information from past jobs/labs?
Redact sensitive data (like client names, novel compositions) and focus on general methods, metrics, or non-sensitive results. Always check with your employer or supervisor.

Q4: Should I focus on advanced projects if I’m an undergraduate or early-career professional?
Not necessarily. Employers want to see methodological depth and clarity. Even a smaller, well-explained project can impress more than a large, poorly documented one.

Q5: Is publication in a journal mandatory to showcase research?
Publications help, but they’re not mandatory. A thorough portfolio can stand on its own. If you have preprints or conference posters, consider linking them.


11. Final Checks Before You Share Your Portfolio

Before giving recruiters or professors your GitHub links, ensure your projects are:
