Very 'home brewed" management. they need some outside influence to help progress
If you did not rise up the ranks, preferably as ex-armed forces service - you will experience a daily routine of insults, 'this is how we always did it', 'why are you rocking the boat" and "i didn't need to go to college"
they work their people very hard, pay low, seldom promote - and rely on "but look at how the stocks are doing"
expect long hours, low pay, and lots of mistreatment.
they are big - and have lots of business
