Today, I went to an agent who introduced hotel work. Do you know it's credible?

You don't even know what the hotel director looks like. At least go to the hotel, talk to the human resources director's office and sign a contract with him. If the intermediary is not a liar, don't sign a contract with them. Who knows if what they promised in the contract can be realized? Don't be opportunistic, or go to the unit to find an interview.
