As I say every time I see this joke, it’s a stupid question when McDonald’s asks it, but a good when when more advanced or complex jobs ask it. A person who is passionate about science is a better candidate for a job at an engineering firm than someone who isn’t. Plus, the question, done right, is asking “why this specific company” rather than why do you want any job. “Why FLIR instead of Tesla?” is a very different question than “why McDonald’s instead of Burger King”.
