How long should a software engineer resume be?
One page for under 10 years of experience, two pages maximum for senior or staff roles. Recruiters scan for impact in seconds, so lead with your strongest quantified achievements.
Should I list every programming language I know?
No. Prioritize the languages and frameworks in the job description and the ones you've used in production. A long, undifferentiated list dilutes the keywords that matter for ATS scoring.
