Process, Questions & AI Prep Tips
Workday is the leading cloud HCM (human capital management) and financial management system for enterprises, covering HR, payroll, talent management, and financial planning. Engineering interviews emphasize the challenges of building an enterprise ERP system that must be correct to the penny for payroll, handle complex financial consolidations, and serve global enterprises with diverse compliance requirements.
