First of all, this has nothing to do with 5 1job. It is just a platform to connect job seekers and employers. As for whether the company website is authentic or not, there is only "obligation" but no "responsibility", so first of all, you should not think that what is on 5 1Job must be authentic.

I am also looking for a job. I advise you not to train. Suppose you are an ordinary company in Shanghai, if you set up a branch in Shanghai, then the Shanghai branch has the right to decide to recruit such a small thing. Besides, even if you apply for a Shanghai branch with a supervisor or above, you can make a decision, just as ICBC Shanghai Branch didn't hear that the recruiter had to go to the backstage for a written interview.

You should have been interviewed by this company, right? The interview place should be Shanghai headquarters, and the training is acceptable, but don't go outside.

You can now investigate the company's background, structure, registered place and other information online, and then make a conservative judgment about whether to go or not. In fact, it is a pity to miss an opportunity, but if you are tricked into doing pyramid schemes in other places, you will really be in a wolf's den.

Sincerely advise the landlord not to go to other places.
