Your idea may be stellar, but it’s very very unlikely to lead to a PM job. PM is a professional discipline, like engineer, UX designer, etc. Even if they loved your idea in the interview, the hiring manager would probably just steal it and tell you to go screw. Conversely if you could demonstrate in an interview that you were a great PM, you wouldn’t need any amazing business ideas. Note that a common question in PM interviews is “Pick a popular product and tell us how you’d improve it”; they’re not looking for grand inventors, they’re looking for people who have the aptitude and skill to manage the process of development and optimization of products. If you truly believe in your idea, and want to get it built, probably best to do an honest assessment of your abilities, figure out who you need to help you, and go for it as a startup. If it’s good and you execute well, someone will buy it. I don’t intend to be mean or to dissuade you, but most great business ideas address specific problems, and it often helps to know a lot about the domain you’re problem solving in. The fact that you know so little about a key job function within those companies (moreover one you want to take on) should give you some pause, you may want to do more research before moving forward.
