Is the recruitment posted outside the restaurant credible?

If you are in a hurry to find a job, go to do odd jobs first. You don't need any work experience to do odd jobs. Just remember what others tell you to do. If your eyes are bright and you see something dirty, you can go up and tidy up. After working for a month, you will understand other things. Not going to the hotel is not a long-term solution. See what skills you are learning. Go to the hotel and find a bigger one. Otherwise, it is easy for a small hotel to lie to you and say that you are unqualified for a few days, and you will do it for nothing.
