What should I know about employer signal analysis?

In the DACH region, IHK/HWK and professional development certificates serve as additional trust signals. Recommendation: Focus your career change on 1-2 target roles and back them up with work samples. In practice: DACH career change: 90-day learning plan with evidence artefacts (project, certificate, case). Limitation: Too many target roles simultaneously significantly reduce the hit rate.
