The interview environment and format leaned toward an open-ended style (I don't know whether this is related to Japanese workplace culture).
Throughout the interview, they repeatedly emphasized that even the company's back-office staff maintain a service-industry attitude.
They emphasized that the company treats its employees well, including employee compensation, training, and development.
(?..Why do they keep emphasizing this? Are they worried that people won't notice, or is it really not something people can feel? The employee turnover rate seems fairly high.)
Interview impression: The company needs employees who are obedient and easy to control (perhaps inexperienced and easy to deceive?).
