In the past, I worked two jobs. One is in a car service point and another one is in an office.
At the car service point. The content is about to use the computer to calculate the bills for customers. From this job, I learned the skill of communication and calculation.
At the office. I need to use excel to type in all the material is on the paper and its price. After this, I need to upload the excel document to the website of the firm. From this job I learned the skill of excel and upload documents.
