Pros
They're so lazy about hiring, so hesitant to offer anyone growth opportunities that it's nearly impossible to be fired
Cons
if you're a "useless" employee, in their minds just a body, not holding the right title, there aren't any growth opportunities for you, not even training, don't buy what they sell at the orientation. Your enthusiasm to help will be abused, you just become the person tasks fall to, and eventually you're responsible for them. You can be doing work above your pay grade all along but then you're told you're not qualified to hold the position you've been doing the work for. There is no leadership, high ranking employees are rarely visible or present. A lot of responsibility is left on the lower ranks, and the untrained, poorly compensated bunch get blamed when the banana republic eventually screws up, in a way that reveals all the corners being cut.
