The company is full of people. Is part-time job reliable?

Not reliable. It is not reliable for a company to fill a part-time job. There is a lot of fraud in this part-time job, and the filling itself is an irresponsible performance of the company's recruitment. So it is not reliable for a company to fill a part-time job. Choosing a part-time job requires finding a regular recruitment or part-time website to know the company's situation in advance and prevent being cheated.
