One on one interview at BCG office. Conducted by a senior recruiter with resume. Basically fit question and little case question. The case is not difficult, but require key ability to solve problem and think logically.

20 minutes, consisting of a 5-minute behavioral question (PEI) and a 15-minute mini case. The mini case is a Fermi estimation problem. The email HR sent at the time said that the interview would be conducted in both Chinese and English. Based on experience-sharing posts from previous years, the PEI was usually in English and the mini case in Chinese. However, my interview this time was entirely in English, so it probably still depends on the interviewer’s preference.
