To judge whether a company is an "crooked" institution, you can look at these.
1. Business License: Apart from the name, it depends on whether the business scope of the license includes the business now being done. If not, be careful.
2, field trips, to see where the company's office is, but also to observe the working status of employees, if everyone is playing soy sauce, there is no sense of service, such a company should not be chosen.
3, online search to see word of mouth, as well as the national enterprise information query, as long as you enter the name, you can query whether this enterprise has illegal information, which can be used as a reference.
Through these simple judgments, you can roughly know whether this institution is formal or not.
