Microsoft L64 vs L65 software engineer

What’s the difference between the two in terms of scope and expectations?

Team dependent. Senior vs principal.

I get senior vs principal, but that’s just a tag. What’s the difference in scope or role guidelines ? Isn’t there a standard in MS?

64: you own problems and drive solutions. 65: you find and own problems. And find solutions. At Principal Scoped is bigger, you might own a entire team’s vertical or a teams eng roadmap

Reality; 65 finds problems and then passed over to 64.
