The structured fields feed into your future contract
Notice Period (Kündigungsfrist), earliest Start Date (Eintrittsdatum), Salary Expectation (Gehaltsvorstellung), these are the fields HR ops will pull verbatim into your draft employment contract. Enter realistic numbers. A 4-week notice period for a senior German role is implausible (default Mittelstand notice is 3 months); writing "flexible" or "negotiable" reads as low-effort and lands the application in the recruiter's "come back later" bucket. State a real notice period, a real earliest start date, and a real salary range with the gross annual figure in euros.
