I've seen some pretty egregious internships adverts, stuff like looking for what amount to a creative director or project manager and asking for years of experiences. This is not how it works here (you can only get an interships through a school so it's implied you're a student and doesn't have enough experiences for big stuff)!
And a head-desk story related to me by a friend who works with company A.
Company A commition Widget-maker B for a widget that includes protocol X. Widget-maker B (WMB) assure them that they can implement protocol X, they have the knowledge and the means.
Of course Protocol X is not something everyone knows how to do, not all widget makers can do it, you wouldn't expect someone straight out of school to work alone on it. And yet what is published the day after Company A and WMB sign? An internship advert asking for someone who can do protocol X
Right, that bodes well for the widget...
