How do you develop your part-time job?

Does it count if I cut fruit in a fruit shop, such as making fruit boxes, cutting pineapples, grapefruit and melons? And I also work part-time as a cashier? When I was in Beijing computer training class, I worked as an extra actor several times. Every time I have a job, I will be paged the night before and make an appointment for the time and place. There are usually worn-out buses to take people to the shooting scene.
