回复：急请各位高人帮忙：今天在谈offer, 新公司的人力部说想要知道从旧公司离职后我unvested stock option

After you jump to the new company, all your unvested Stock options will be in the water.

They want to know how much you will lose. And they want to use this number as a base when considering what kind of offer to give to you.

You do not have to tell them if you already negotiated a much fatter package, so you will hide your previous poor numbers.

You will tell them if your current negotiation doesn't produce much fruit, so you want use the previous numbers to prove your true value.

To answer you question, the answer is: It depends...
