Overall the impression is positive. However, the interviews were quite quick, so if you got delayed at some stage, you would not be able to finish the case or ask personal questions. The cases were solvable, and interviewers were ready to help you out.
First - a Fit interview with Partner, which supposed to be followed by Case Study Inetrview, but I unexpectedly faced a standard Gorilla test, the results of which HR refuse to share
Interview questions [1]
Question 1
Are you ready to subordinate to a manager that is younger than you?
Good interview process. Response was quick and was able to hear back on the outcome in a couple of days after the interview. 3 stags overall including the initial HR screening followed by a case study.
Case interviews in both Japanese and English. Case interviews were more like Fermi estimations for market size/customer size rather than formal business-structured case interviews. Brief introductions at the beginning, but generally not too focused on socialization.
