Also, so far after 12 years plus working, they've only ever asked for for that AFTER giving me an offer. I know many people in HR, and the main reasons they want that is to verify that you were working with said company for X amount of money as you've claimed before. Also, they have to justify he amount they offer you - some bigger companies will pay you at least the minimum of the band of the job, regardless of whether you asked less than that or not. So.... to me it's a formality, nothing to worry much about
