Although you applied for a trainee assistant, you can't do well if you haven't worked in DQ before. So we still have to start with the waiter.

In fact, DQ trainee assistants usually have to serve, and may also need cashiers or make products. Different from ordinary waiters, assistants, managers, etc. You also need to take stock, purchase goods, make reports, typeset, and so on. Not just directing others to do things.

If you want to work in DQ, there is no great future for you to work in the store all the time, and the salary can't be particularly high (in my opinion), unless you become a regional manager or something in the future. It will be ok if you can enter the company.
