My mentor read my resume for four minutes and only asked one question: what did you actually build

Handed over a resume I'd polished for two weeks — action verbs, quantified everything, the works. She skimmed it, set it down, and asked what I'd actually built with my own hands versus what I'd contributed to on a team. Realized half my bullets were technically true and completely uninformative. Rewrote the projects section around three things I could explain in detail if someone pushed back, cut everything else. Shorter resume, better interviews since.
