How to calculate the overtime pay on working days and weekends for Huawei outsourcing software testing positions in Wuhan, and how much can the year-end bonus generally be given?

Double breakpoint

Holiday 3 times

Default overtime on the last Saturday of every month.

It seems that there is a 7-hour snack subsidy after 9 pm, and Huawei has its own canteen and shuttle bus, although it costs money. . .

Generally speaking, the work is very enjoyable and everything is available. Different outsourcing companies issue different year-end awards. I wonder what it is. . I wonder if it's a pit.
