⚠️ Common Mistakes to Avoid

  • Don't present yourself as purely a backend or frontend specialist—this role requires full-stack leadership.
  • Avoid vague claims like 'improved performance' without specifics—quantify your impact (e.g., 'reduced load time by 30%').
  • Don't neglect soft skills—this role involves heavy collaboration; failing to mention teamwork or mentoring can hurt your candidacy.
