Part of the interview was in Czech and part in German and very few questions in English because German and English are the languages which are used in the switch board of the company.
Because the interviewers had allready my CV they don´t ask about my previous jobs experience and knowledges but about the reason I applie for the position and mostly how many hours per week I can work for the company (because it was for part-time job). The last question was about my salary expectation.
The interview took some minutes. It was not long.
There were me and my two (future) bosses.
