We have engineers making up to $250k total comp most are in the $150-200 range, we have offices in LA, Palo alto, and NY, we pay relocation of some kind, and we want generalists that are really good.
It sounds like your comp is great - as in truly competitive.
That salary range would probably make you standout from the crowd. If only there were some way (short of interviewing and getting an offer) for a possible candidate to know that..
I see salary ranges advertised all the time in the New England area so its not impossible.
Like some else mentioned; when I don't see a salary range I assume it isn't great or maybe they don't want to piss off the current employees that are working for below market rate.
I can't change HR policy, so I can't publish it, but I bet if I did it would cause a lot of headaches. Very few people are worth the top end salary, and most aren't self aware enough to realize it.
