Ventajas
Can not think of any pro's regarding compensation.
At times people were friendly that does not pay the bills
Desventajas
Work for free. Basically, you work half a month for free. Like a donation to the company. Owners love free workers. Mangement expects you to perform a multilayer of tasks for free. I did not know this position, so I tried it out. So, you are a glorified parts specialist at best. You are also a delivery person. A lot of times you are not getting paid. Very low base. I would not try it again
