I'm the head waiter in the restaurant. There is no manager in charge of the catering department. I interviewed all the service personnel. I know nothing about the interview. What should the interview say? The basic requirements for recruiting waiters are: good facial features, moderate height, good health, generous manners, good language skills and clear articulation. Good at communication, strong affinity, etc. You just have to grasp these aspects. You can ask the interviewee to introduce himself first, from which you can find some advantages and disadvantages. Generally, hotels are afraid to recruit some shy people, who are too introverted, so they are not suitable for service work.
