Who's to say the bottom is the actual bottom though? Suppose I pay all my engineer's 170, 170, 190, and 210. What prevents me from listing the salary range at 100-210?
And this is exactly what Netflix is doing, because they don’t pay any of their senior engineers (these listings were for senior positions) only $90K. I’d be surprised if any (in the U.S. at least, and this is a U.S. job posting) make under $200K.
You're right, though the article is talking about pay transparency laws in several different US states, so perhaps some have this loophole and others don't.
