Ask HN: Determining worth and negotiation points during job offer?

I'll be receiving a job offer soon from one of the top 3 and was wondering what your strategies are for determining worth and negotiation points. Fresh BS CS grad, but I'd say I have roughly 4x the work experience of your typical fresh grad at some pretty notable places, the majority of it being pure research in ML and also have a non-profit startup. Is this sort of stuff a negotiation point?
