The interviewer is a gentleman. He didn't introduce himself even his company. The whole process is very cold! His voice and face is even colder.
I was very seriously talking about my experiences, skills, and education, but he asked me: what are you doing? I didn't understand his words, and even couldn't read his mind, or had no enthusiasm to sell him my strength, since his face was so cold, and he behaved that he didn't interested in anything, and I was just bothering himself. After that, I didn't see any words and just left.
