Phonographic Performance interview questions

I didn't find life in office. Faces of all employees including receptionist and peon were dull. I could see HR from reception area and she was not busy though I waited for half an hour . No one has asked for water even. After my reminder I was called for interview. HR was continuously talking or chating over phone. She didn't apologize single time even after attending personal calls and chat. Only one phone was work related. Rest of the phone and chat were personal. She was giving weird expressions when I was answering her questions as she was busy giving more attention to chat then interview. I was really upset with unprofessional behavior.
