A lot of the hiring process seems to be about making sure you'll write/say the correct lies.
Look at common intro paragraphs for résumés. They're horse shit, and everyone knows it, but deviate much from the usual "dedicated team player who blah blah blah" and it goes in the bin. Doesn't matter that it's horse shit—it matters that you follow convention.
"Where do you see yourself in 5 years" -> honest answer in 99% of cases is "I don't know, but odds are it'll be more or less the same place as now but slightly richer and fatter". You cannot say this. Doesn't matter that it's true.
"What makes you want to work at our company?" -> honest answer in 99.9% of cases is "it pays enough money and seems less awful than my other options for performing activities that pay similar amounts of money". You really can't say this, and even a heavily buttered-up (that is, coated in bullshit) version isn't likely to pass muster. Lie or GTFO.
Not telling the expected lies is a great way to end interviews, or never get them in the first place. The only actual purpose it can possibly serve, that I can think of, is to weed out some of the crazies and eccentrics very quickly. Someone more conspiracy-minded might come up with a bunch of stuff about how it ensures the applicant is sufficiently cowed by this horrible economic machine we all serve, but I suspect the situation is more of an accident than anything with much intention behind it.
Yes, yes, there are exceptions, but this is the reality that the mass of employment-seekers face most of the time. Tell the right lies or go in the bin. One of the more shocking and difficult-to-cope-with elements of adult life if you're brought up to value honesty. Try to talk to people about it and many seem to become confused. "But that's just what you put on it. Here, you need to add something about how you're a self-starter." Sigh.
[edit] I would add that the "why do you want to work here?" question carries the bonus stupidity/uselessness-factor in that no place where someone wanted to work for reasons other than just money and it being less shitty than the other options would ever feel the urge to ask it. SpaceX doesn't have to ask. They launch fucking rockets in to space. You sell (e.g.) Point of Sale software, so you ask because there's no obvious answer other than "you pay money, I want money". It's a question dripping with insecurity.
