L6 ICs are pretty rare - it already is a top tier of seniority in engineering
Is Google really different from other companies? I talk to a lot of Amazonians (AWS Hero, FreeBSD/EC2 maintainer) and my general impression is that developers below L7 ought to be classified as "Junior" -- my mapping is basically L4-L6 = Junior Developer, L7/L8 = Developer, and L10 = Senior Developer. Anything which doesn't have L7+ involvement gives me major "these kids need adult supervision" vibes for all the newbie mistakes they make.
