Is it true that the train conductor is recruited online and said after the interview that the salary is above 10000, then trained and assigned to the train?

Just to be clear, is it an intermediary? If it's an intermediary, it's probably a scam. Because this kind of work is usually recruited by the relevant departments in that area, it is very formal, with contracts and guarantees.

If it is an intermediary, ask which region and department you are recruiting for and make a list. Then, check Baidu yourself, the phone number of the relevant department in that place, etc., and ask if it is the client's recruitment. Be sure to ask both parties whether they know each other or just the wishful thinking of the intermediary.

Before you call, make a list of the questions you want to ask. Don't be fooled by people when calling, or even forget the key questions to ask, not once, twice, twice or three times. There are many things to grind, so you must get to the bottom of it and solve all your problems so that you won't be cheated.
