Why are the interview addresses of some companies in hotels?

There are two possibilities. One is that if the fraud company goes directly, it may get into pyramid schemes. The other is that their company has no office in that city or is not in that city. They just used to recruit and interview at the hotel. However, before you go, you can search the relevant information of their company and the reputation of their company from the Internet to avoid being cheated. I hope a little advice can help you.
