TL;DR probably impossible unless you can speak Japanese (Or get a different set of interviewers). First they send you a coding challenge on hackerbyte. It was around leetcode medium level. After that, the first round interview was with two people. They asked some system design question. After talking through requirements, they would probe and ask detailed questions about the infrastructure (ex, how would you go through hosting this, how do you set up the CDN via the DNS config). Second interview was a one on one pair programming session. The interviewer asked some more leet code easy-mediums. Up until this point everything is smooth. All prior interviewers can speak english more or less fluently. Third round interview (rejected here) was with two members of the infrastructure team. The second member who seemed to be the more senior member was around 5 minutes late, as this interview was after his english lessons. As we get started, it is clear that this was the senior member and was completely unprepared. In addition to not having any prepared questions and being late, it would take him approximately 5 minutes to think of how to word the english for some personality type question. No tech questions were asked here and the interview was pretty rough, given that the level of English was not sufficient to conduct even a non-tech related type interview. Anyways, the interview process itself was pretty fast and professional. The company responded with the outcome within 3 days of the previous interview.
