Being an intern at a company can prove to be a rough deal. It is the kind of thing that every ambitious college student has to do if they want a chance at a respectable job offer once they graduate, but they are almost always going to be on the lowest rung of the totem pole. It's often unpaid, and the salary isn't usually anything to write home about if there is one. You're not responsible enough to do any of the interesting work, but they will probably take full credit if you do manage to do anything notable. It's a challenging early career move.
Nonetheless, employers who take on interns have a vested interest in them having a positive experience. They want to look like a company that is good to work for, if only so it boosts the quality of applicants they get on their ghost job postings. Even if they do not provide the greatest internship experience, they may try to manipulate those who do not know any better to make it look like it is better to work for them than it actually is. It is the only reason that companies manage to hire in the first place.
