EY is far from a nightmare, yes it does have areas that need fixing but its no worse than lots of other places around the world.
When I read all this nonesense I wonder if this is the same EY they are talking about!
For all you prospective new joiners dont listen to the doom and gloom merchants, its not that bad....certain areas do require fixing and fast, but the vast majority are good guys...do your own research then decide if its for you...most important be realistic in your expectations.
Good luck!
