> You call devs Junior until they have over 5 years experience? Wow, that’s harsh

Less than 3-4 years is absolutely junior dev. Up until around 7 or 8 years is mid-level. Passing beyond that would be senior dev and the other titles then follow.

With the obvious note that it's not strictly time bound - someone could easily get stuck at mid level for much longer if they aren't progressing. It's pretty hard to still be only junior after 7+ years
