Markus Bühner is a professor of psychological methods and diagnostics at LMU Munich. In a 2015 interview published by the university, he spoke about hiring. Sympathie ist zunächst etwas vermeintlich ganz Wichtiges. At first, liking a person seems very important. But choosing a likeable person who is not suited to the job will sooner or later cause high staff turnover. Liking may decide only between candidates who are all suitable. Ansonsten gilt: Erst kommt die Eignung, dann die Sympathie. Otherwise the rule is: first suitability, then liking.
