Why Keywords Are Everything for Software Engineer Roles
Tech companies receive hundreds of applications per role. Every major tech employer uses ATS — including Google, Meta, Amazon, Microsoft, and most startups. ATS filters for software roles are often highly specific, scanning for exact technology names, programming languages, and methodologies. Missing key terms means automatic rejection regardless of your actual skill level.

How to Use These Keywords Naturally
Do not just list keywords in a skills section. Work them into your experience bullets as context. Instead of just listing "React" in skills, write a bullet like "Built customer-facing dashboard in React serving 50,000 daily users." This satisfies both ATS keyword matching and gives recruiters the context to understand your experience level.
