| Role fit | Requirements repeated in the job description | Projects, tools, interview rounds |
| Technical depth | Can you explain the trade-off? | Architecture notes, debugging example, code review |
| Communication | Can you explain the decision simply? | Situation-action-result examples |
| Next step | One focused improvement | Updated answer, mock interview result or project note |
