Case 1
The resume says: "Worked on backend services using Node.js and helped fix bugs."
The roast: This bullet has all the commitment of someone standing near a kitchen while other people cook. 'Worked on' and 'helped fix' describe attendance, and the only concrete noun is a framework name. What did you build, at what scale, and what changed?
Why it is weak: It contains zero evidence: no system, no scale, no outcome. A reviewer cannot tell whether this person shipped a payment platform or restarted a dev server twice.
Improved: Rebuilt the checkout API in Node.js, cutting p95 latency from 820ms to 290ms for 15k daily orders and eliminating the weekly timeout incidents.
Why it works: The rebuild names the system (checkout API), the action (rebuilt), the scale (15k daily orders), and two results (latency, incidents). Now the same sentence proves seniority instead of presence.
