Why your resume summary is doing the most important job on the page
ATS systems weight text at the top of your resume more heavily. Your summary is the highest-scoring real estate on your entire document. Recruiters spend an average of 7 seconds scanning a resume before deciding whether to read further.

The 5 mistakes that make summaries fail
- Generic adjectives instead of specific claims ("passionate, detail-oriented")
- Listing technologies without context
- Writing it for yourself, not the role
- Leaving it vague about what you want next
- Writing it once and never updating it
