4. Body Paragraph 2: Show Fit & Passion: Reference company values/research. Ex: "After reviewing Navigant's entrepreneurial spirit (MIT CAPD), my energy sector analysis matches perfectly."

5. Address Gaps (Entry-Level/Career Change): Highlight transferable skills or projects. Ex: "Though new to full-time roles, my Linux backend coding from CS coursework supports Mayflower's goals (ResumeGenius)."

6. Strong Closing with CTA: Reiterate value, call to action. Ex: "I'd welcome discussing how my skills drive your team's success."

7. Proof & Submit: ATS-check (80%+ score via Reztune), 10-12pt font, 1 page. Email subject: "Software Engineer Application – [Your Name]".
