I'm hiring right now, into a critical role for me. I have lots of questions for new candidates about what they were doing before at previous employers. However I will not feel the need to ask what they are paid. I have been asked it on several occasions and every time it was an attempt to pay me less than the company had advertised for the role. I can think of so many reasons why someone's pay may have been out of step with their role in the past, and none of it is relevant to how I wish to inventivise them now. So no I don't think it is dismissive
