What should I know about matching and recommendation systems?

In the DACH context, AGG, data protection and transparency requirements must be explicitly incorporated into matching and recommendation systems. Recommendation: firmly establish logging, approval checkpoints and documented exception rules for the ATS workflow. In practice: example 2 -- review cycle with audit log, KPI tracking and escalation path. Limitation: overly generic rules without role or legal context reduce quality.
