Sort of. The main issue is that AMZ/AWS doesn't differentiate (by title) between someone recently promoted to L6 (generally ~8-10 YOE) and someone deep in to L6 (~12-15 YOE). Other companies solve this with the Staff Engineer title, but AMZ doesn't have that. If you're an L6 who reports to an L7 Sr. Manager then you're functionally a Staff Engineer and supposed to be on the Principal track. Mileage varies across orgs/teams.

Gist: "junior" L6 SDE is more like Google L5, "senior" L6 SDE tracks mostly with Google L6 (or even L7 in rare cases).

Are you sure about this?

I think it's more like Google junior L6 SDE is equivalent Uber L4.5, which itself is about the same as senior AA at Oracle (= like a L11 at Twitter).
