Started with behavioral interviews, basic question such as how do you manage conflicts or what's the achievement that you are most proud of. Second one was still on the phone plus a case interview. The questions might be random. Mine was "what's the annual copier demand in China?" The interviewer has McKinsey background and conducted the interview emotionlessly. Cut to the chest when answering the questions. No questions like "walk me through your resume" because he's watching your resume and would like to know something else.
