waiters can go to hotels and restaurants to find jobs, and recruitment information will be posted at the door. Of course, the most direct way is to find a job through the recruitment app, which is the fastest and most convenient. Before, I came into contact with an app called the shift, in which there were many grass-roots positions, and there were videos of working environment recorded by enterprises, so that I could learn more directly about the working environment of enterprises and find jobs that suited me quickly.
