Is it a lie to apply for the night shift manager of a hotel in Chengdu and let me buy a prepaid card starting from 300 yuan before going to work?

Well, this must be a lie. Don't go. Regular companies don't need you to pay a penny, and they won't let you pay in any other name, and they won't let you take your ID card or any other documents as collateral. Don't believe such a thing. What's more, they will say that your treatment, your future salary and future are very good. If you don't believe this, you should work hard.
