Is the Henan project recruitment of China Railway 22nd Bureau Group Electrification Engineering Co., Ltd. a pyramid scheme?

Tell me about my experience. Last time I went to the China Railway Fifth Bureau in Yongzhou, Hunan Province for an interview, I was detained for more than ten days. Their contact person is Manager Yu (the mobile phone number can't be found online now), and their email address is. Now it is found that Jiangxi China Railway Fifth Bureau also uses this mailbox. They usually let you have a physical examination, and then there is a special staff reception, saying that the company does not allow outsiders to come in and out casually. In the end, they won't take you to the company, but take you to accommodation and lock you up. So if they say that someone will pick you up and take you to the company first, then you must never go. Don't be fooled by what they say. The population inside is quite good, which will make you feel very talented. Some people may wonder why I came out. With this question, you can go to see the new pyramid scheme. If they ask you to buy daily necessities, cigarettes, alcohol and snacks, it must be pyramid schemes. There are also pyramid schemes, and there is generally no fixed telephone. They usually use mobile phones, you know.
