I think you are overestimating companies... For most of my career (12 companies, 3 of them my own) it has been easier to get hired at a higher position in a different place than being promoted internally.
When you are applying for a new, higher, role having enough experience at your current level, being sure enough of yourself and demonstrating the ability to create value within the test period will be more than enough for most companies out there.
When trying to get promoted internally you have to deal mostly with office politics. In a way, the quality of your work is only a small part. And, if you are good enough, it can go against you, I know people that have been skipped for promotions for years because their managers knew that the whole department depended on them.
Of course, there are exceptions and I admire those companies, but they are just that: Exceptions.
