🚨 Most resumes fail in the first 7 seconds! 📉 Recruiters skim, not read. If yours isn’t clear + eye-catching, it’s ignored. ⚡️ Here’s how to make yours stand out instantly 👇 🔥 Why most resumes fail: ❌ Cluttered & hard to scan ❌ Generic — blends in with hundreds of others ❌ Missing metrics/impact ❌ Poor formatting ✅ Why this template works: ✨ Clean & professional - recruiters spot key info fast ✨ ATS-friendly - passes initial filters ✨ Achievement-focused - highlights measurable results ✨ Balanced - detailed but not overwhelming 💡 Tip: Use numbers. Instead of “Improved sales”, say “Boosted sales by 30% in 3 months”. 📸 Attached is a resume sample you can model yours on - clear, powerful, and recruiter-friendly. 📌 More tips & resources in 👉 @GechDevTalk
