Recently, I received an interview from Cosmic Information Creation Co., Ltd. in the form of telephone interview? The post is to do software testing.

The company is not fake. It may recruit outsourcing jobs related to financial testing. Of course, it may be tricky, that is, trainees may not be left behind all the time. So I think if you are worried about fake goods, you can call this company on the grounds of consulting for an interview. If it is confirmed that the interview is really unsuccessful, then you can ask about the signing of the contract before going to the training. If the other party is happy to tell you, come to the company to sign the contract, it's basically no big deal, but you have to read the contract carefully. If she said she wanted to see the training results, that's what I said earlier. Of course it's not a big problem. If you find it acceptable, don't go.
