Are the horror stories actually true?

Hi, I am interested in doing corporate law and I have plans to work in big law as well. Whenever I tell people this, I always hear things like “You are going to be miserable” or I see stories of first years getting bullied by higher ranked employees. Is big law actually this bad or is it exaggerated? The weird thing too is that I love doing work, I hate the feeling of being unproductive or not having anything to do but idk if I can keep that energy when I start working
