Frequently Asked Questions
How long should a software engineer resume be?
One page if you have under 8 years of experience. Two pages maximum, ever. Recruiters skim — density and clarity beat comprehensiveness.
Should I include a GitHub link or portfolio?
Yes, in the contact section. Make sure the linked GitHub has at least 2-3 polished, recent repos — a sparse or stale GitHub can hurt more than help.
Do I need to list every technology I've touched?
No. List the ones you'd be comfortable being grilled on in an interview. Tool sprawl signals shallow experience — depth in 8-12 things beats surface knowledge of 30.
