⚠️ Common Mistakes to Avoid

  • Submitting a generic resume without tailoring it to .NET Core, Azure PaaS, or sustainability-focused projects—this role requires specific tech and mission alignment
  • Failing to demonstrate scalability experience; avoid vague descriptions like 'worked with Azure' without detailing how you built scalable solutions
  • Neglecting to show collaboration skills or code quality practices; not mentioning tools like Git, testing, or clean code principles can signal poor fit for team environments
