Content Principles

Achievement Over Responsibility

Transform duty descriptions into impact statements.

Formula: Action Verb + Task + Result/Impact

Examples:

• ❌ "Responsible for managing social media accounts"

• ✅ "Grew Instagram following from 2K to 45K in 8 months through targeted content strategy"

• ❌ "Worked on improving customer satisfaction"

• ✅ "Increased customer satisfaction scores from 3.2 to 4.6/5.0 by redesigning onboarding process"

Quantify Everything Possible

Include metrics wherever available:

• Percentages: "Reduced costs by 23%"
• Dollar amounts: "Generated $1.2M in new revenue"
• Time savings: "Cut processing time from 3 days to 4 hours"
• Scale: "Managed team of 12", "Served 500+ customers daily"
• Frequency: "Published 3 articles weekly", "Conducted 15+ interviews monthly"

STAR Method for Achievements

• Situation: Context or challenge
• Task: Your responsibility
• Action: What you did
• Result: Measurable outcome

Relevance Over Completeness

• Tailor content to target position
• Emphasize transferable skills for career transitions
• Recent experience deserves more detail than older positions
• Omit irrelevant experience unless it fills gaps
