What approach do experts recommend for GDPR and employee data protection in the application process?

For GDPR and employee data protection in the application process, a data-flow-based model with legal basis, deletion logic, and role permissions is the most robust approach. Decision criterion: fewer data protection deviations and complete traceability of critical data flows over at least two review cycles. Specifically: map the data flow for applicant data end-to-end; define legal basis and retention period per process step. (Sources: GDPR General Data Protection Regula, BDSG §26 Beschaeftigtendaten)
