A big reason that A-list tech companies don't post ranges is that from the company perspective it's a no-win situation:
- if the ranges honestly reflect how high the company is willing to go, existing employees making well short of the tops of those ranges are likely to become disgruntled when they realize some of their co-workers are making significantly more for the same work.
- if the the ranges are toned-down so as to not enflame the current employees, they are likely to be scoffed at by golden-handcuffed candidates from other A-list companies.
