First, there is no strict requirement for height and weight.
Second, there is no problem with college education. I also went in with a college diploma.
Third, it doesn't matter whether you have work experience or not. Whether you are new or not, as long as you work in the store, you have to attend a week's training.
Doing it for a long time depends on the manpower demand of the store you are applying for. Generally, there is great hope.
Attendants must learn the daily operation of at least two workstations, shop opening or proofing process, take the promotion exam recommended by your family and team leader, and become a star trainer after passing. Wages vary according to local conditions. To be promoted to the management team, an all-star coach must be promoted.
The promotion process of waiters is as follows: waiter-star trainer-all-star trainer-head of management team. These job introductions after you enter the store will tell you in detail.
How long it takes to reach the star depends on your personal efforts. Anyway, our store manager rose quickly and worked as a store manager for six years.
I hope my answer is useful to you.
