Re: My first IT job and this is what I got to work with... I've seen the same sort of thing happen at my work.
In order to minimize downtime and get things up and running as fast as possible, people pay no attention at all to cable management and just go ahead and connect the cables every which way.
After that, the equipment is up and running and it's impossible to do any cable management without taking the equipment down for a bit, so cable management never happens.
Rinse and repeat a few times, and you end up with atrocities like the one in the picture above.
