Workday (Recruiting)
Workday Recruiting (2026): Unified Data from Applicant to Employee
Workday Recruiting excels at internal integrations—HRIS, payroll, benefits, time, and learning—creating a single source of truth across the employee lifecycle.

Pricing is enterprise and quote-based, commonly six figures for global deployments.
