There is usually a lot of overtime at work. Especially at the end of the financial month and in the middle of the month, it is very, very hard. And bpo is generally a part of finance. You can do without any financial knowledge. Training will be held in a few months. This is a mechanical repetition. Generally speaking, spoken English is rarely used. Even if you communicate with Japanese customers, it is usually an email. It's just a few words over and over again. I want to practice my spoken English and deal with the Japanese. I still suggest you go to a Japanese company. The kind that can directly contact Japanese colleagues. Bpo really has no future.
