I think the sort of more general point, rather than "build something great that someone at Apple notices", is that Graduate and Internship programmes are scale businesses. They get thousands of people applying and will hire atleast dozens, probably some FANG are hiring hundreds. So yes, we're all special snowflakes, but that's not what this process is for. It's about harsh rounds of easy to design problems to winnow the field.
This totally changes when you're a specific candidate with skills Apple values. What this guy experienced wasn't an interview process. They had already decided to hire him before what he described as the interview process. They already know he's good, he experienced the talent acquisition process. The bit that happens when the company has already decided to hire you and is now doing everything it can to sell you on the job.
If someone outside of recruiting contacts you about a job at a company, you will not experience a normal interview process, because they're already quite likely to want to hire you.
