I met so many people at Oracle who were just faking their way through work, and not just work, come to think of it, really faking their way through life.
Over the years I have seen people at other companies faking their experience, lying on their resumes, etc. What does that really get someone? Lying about their education, lying about their background, lying about their experience.
Just gets you in over your head and puts you in a job you can't do.
Many years back at another company there was a guy who took a job as a unix administrator. Had no experience at all. I needed him to move a unix machine to another company so we could certify the software on it as working with the other company's software.
He unplugged the machine and had no idea how to reconnect it to the network at the new company. Network could be plugged both into the mother board or a network card on this machine. It was plugged into the network card originally, then when he moved it, he connected it to the mother board and the machine was not using the port.
At that point, we turned to line mode commands to try and troubleshoot the issue. I didn't know what he had done wrong, but there was no network. I was half inclined to climb up on the table/shelf where the box was and look, but a director knew someone who knew right commands to redirect the network to the port on the mother board.
But, I found out, that the "unix administrator" didn't even know how to "cd" to a directory. He didn't know what a directory was. He knew nothing, was completely useless. He'd completely invented his resume.
I complained afterwards to his bosses and everyone around him to no avail. Then, the windows guy caught this fake disconnecting another computer to move it. And he found the guy labeling all the connectors with little tags like A, B C and then labeling the places they plugged into the back of the computer with same letters. He told me he knew the guy was a fake when he labeled the POWER CABLE! Finally, he was gone. Got a paycheck for several months and knew absolutely nothing about his job. I expect he is still somewhere doing the same thing.
You never know who is a fake and who is not. Someone claims to have an ivy league education? Really? Who knows. Maybe his friend also has an ivy league education, different school. Maybe all invented? These days anyone can put anything on linkedin, none of it verified. Who knows. People make up experience. Also, had another guy that claimed he ran part of a project at another company. I happened to actually know the person who did that, so I was able to give them a call and verify that the guy had nothing to do with that part of the project. Lies, lies, and more lies. All completely rampant at Oracle.
