⚠️ Common Mistakes to Avoid

  • Applying with only frontend or only backend experience when this role explicitly requires full-stack proficiency with Angular, .NET Core, and SQL
  • Failing to demonstrate specific experience with both legacy technologies (.NET Framework, WPF) and modern frameworks (.NET Core, Angular micro frontends)
  • Presenting generic project experience without highlighting work on global projects or product development (vs. custom client work)
