Honestly, I really can't think of any advantages. It's just an ordinary company with no benefits worth mentioning.
The reviews from other people are all true, so don't doubt them. The company has even violated the law and been fined by the Labor Bureau. If you really want to join, I suggest first checking the company's operating status, because the company has issued unlisted shares and is required to disclose its operating status. Those who know what they're doing will know how to look it up. I strongly recommend checking it out. If you really need a job and decide to come, I hope you can treat it as a form of personal cultivation and doing good deeds.
