How do I implement probation period, fixed-term contracts, and notice periods before contract acceptance in practice?

Germany should separately disclose at least the type of fixed-term contract, probation period, and notice period in the job listing, offer, and contract check. Offer page: display probation period separately from fixed-term status and start date. Employer backend: mandatory field for term type and contract duration. Caution: special configurations in collective or individual agreements can override standard logic. (Evidence: TzBfG Gesetze im Internet, BGB §622 Kuendigungsfristen)
