Yes. I managed a team and had to hire many people. My company provided me with a mountain of data that was broken down by location, job title and years of experience. The data was pretty accurate, at least for San Francisco, but I have no way of knowing if the other locations were correct.

Two stupid things on their part...I got headcount, not a budget. So when negotiating salary, it wasn't in my best interest to haggle. I'd rather have happy relationships with my direct reports than know that I screwed them out of a few dollars on behalf of the company. Had they made it my duty to make the numbers add up, I might have been a bit more frugal. Oh, and they didn't filter the data to only show me positions below my title. So I went into my reviews armed with the exact market salary data that the company used to negotiate with me.
