The recruiter supposed to call me at agreed date and time. He did with a short delay. His voice and way of talking were not so friendly. He introduced about the company and the position. I started to talk about my backgorund. He stopped me at some point and asked me my knowledge in German Language. I said that I don't know. After this response he stopped this call without any word. I thought it is a technical problem. Waited for a while. There was no call. I tried to call him, he didn't reply. After that I sent an e-mail to him about it. Never replied.
