submitted resume and waited about 2 weeks and got called for a phone interview. the phone interview was about 30 minutes and included 3 questions: 1. the first question is a market sizing question 2. the second question is a mini case, market is on microchip 3. the third question is a very random question that tests your short-term reaction

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.
