I have an experience as a data encoder in an electronics company for 2 years. Also, as a design technician in an automotive company for 3 years.
As a data encoder, we used Microsoft Excel to make a transaction record because we transact our products to different company.
As a design technician, we used our personal software that is similar to AutoCad. We also used Microsoft Excel to properly design the wiring harness of a 4-wheel and 2-wheel vehicle.
