Extremely brief company introduction followed by a lengthy Q&A sesssion full of cliche questions (no in-depth technical discussion or anything).
HR and a person to help with the translation were present. Both did not seem too enthusiastic about the process and it looked like they were just filling some monthly "interview quota" since the very next day I got rejection feedback of "Skills Mismatch".
The person helping with translation, however, was collaborative and happy to answer my questions as well. The HR was just constantly writing something down after asking 3-4 cliche questions "Why you look for job, do you interview with other companies, why Japan".
P.S. Might be worth mentioning that "polite formalities" like introducing themselves or thanking candidate for the time were also skipped and in the end I was asked to "hang up from your side, we (HR and the translator person) need to talk in private".
