I see two kinds of technical job interviews: the FAANG style and the rest. Let's start with the latter: the problem is that not every company wants exactly the same developer profile. Acing a standardized exam means that you are really good at what the exam is testing. But because you excel at leetcode interviews really does not mean that you are the best fit for most companies in the world. Maybe this company will want somebody with experience in a specific framework ("we have a Qt mobile app", "we work with Laravel", "we write firmwares", ...), that company will want something with domain knowledge ("we need someone who understands the medical domain", "we need someone who understands maritime navigation", ...). You can't standardize that. For the small parts you could standardize, it exists: a CS degree, "5 years experience as a dev", etc. For the former, it seems to me that it is already pretty much standardized. When you interview for FAANG companies, you need to read a lot about the interview process and prepare it like you would prepare an exam. If you are super ready for the interview at Meta, you are also super ready for Google. It is some kind of standard already. Maybe the FAANGs could team together to share the exams, but the economy would be marginal (otherwise they would have done it).
