This is before I retired I made a (Video resume) back around 2011 operating a manitowoc 4600 digging unshot rock at 60 foot depth. You younger operators should make a video resume to prove what you say you can do, I trained a number of operators and tried a lot of operators out for jobs that said they could when they couldn't and one mistake could easy cost $50,000 or more in damage. A video resume also helps if your applying for a operators job out of state it will prove your ability without having to go there first and prove yourself the video shows your skills and will get a company more interested in you for the position, the first part shows the machine operating then you get a view from inside the cab, that shows your the one pulling the leavers. Hope this helps you out.
