Thanks for the input everyone.
This isn't a conventional interview or job process because I was approached by a director whom I work very closely with to come work for him (same BU, different group). Him and his staff are already well aware of my capabilities and experience so the interviews are more of a formality than anything IMO.
Like Schnell said I don't want to be "slick" in the interview(s), but if I can ask the HR rep via a simple email and they have to tell me, that's cool.
Play your cards better, do not ask for the salary range in writing, that puts them in a spot.
A phone call works far better because it brings something to the discussion so lacking these days, a personal touch, your human side instead of an email that they might think can get copied and pasted all over the place. Besides, what you might find out could be just for you, not everyone else. It can be amazing how one person can get a certain level of compensation while another gets far less and it has nothing to do with anything except how your pursure that compensation.
There is something called hire above maximum. This is reserved for candidates who display the qualities needed by the company in a way better than other candidates do, using prior salary is one way to grease that skid.
Sometimes you can ask the question as one seeking to determine how competitive their compensation packages are.
Take government jobs for example. They always have a published salary range, yet, you can get hired above that range by finding out a specific talent or skill they need that allows them to hire above maximum. Private companies often have pre-determined ranges too. Break out of those ranges or at least head for above minimum.
A sample question, since all of the above is worthless without at least one concrete example:
Good __________ ( not a Hi or Hello), my name is _____________ (full name not an alias), I need some help, (people love to help) I'm trying to find out if my expectations for the job/position of ___________ are reasonable in your company. I'm seeking a range of __________, do you know if that would be considered and if you're unable to help with that question, would you direct me to the person that can help?
Unless they have a strict prohibition against general info, believe me, someone there is going to tell you. There are no such things as secrets or confidentiality, the right approach can get past any of that.
