During an HR interview over the phone (but this is well into the process, I've met with 7 people already in the past weeks I've progressed to the final round next week) I was asked point blank "what do you currently make?" I deferred and addressed the posted hiring range for the job and that I am very comfortable with that range + benefits. The HR interviewer responded that they understand me keeping it confidential but indicated that it would be helpful to disclose it and we moved along with the call.
All in all I felt awkward about the exchange. The hiring range whether low or mid range is more than I make now but at the time of the call feared that would incentivize giving me the low end offer, but I'm still concerned about how I responded.
Should I include in my thank you email my current salary or should I just let it go until since I have another interview follow up set up with the company and wait until negotiations to talk about it again?
