Not sure how many in here are involved in maintenance, engineering, or a related field, but I thought I'd give it a shot. Being a fresh grad in Mechatronics Engineering, I'm currently seeking out relatively big companies that are willing to take me in as an engineer. As it so happens, Sony seems to be willing to give me a try... I am currently scheduled for a 3rd interview with them on the coming 23rd November. The catch is that potential candidates are given homework to be completed and presented to them on that date: we are to create a Total Preventive Maintenance Plan for any machinery/equipment of our choice. The presentation must be in-depth, and must justify all of the choices made, such as the frequency of maintenance. Only thing is, I'm not sure where to start... Does anyone have any pointers for me on this?
