No. Mostly I've been offered as low as 1/3 my current salary. And I know of places I can go for a 50% bump if I want to give up my personal life (I don't) for a couple years . But I have helped peers in managing their careers / salary negotiations and found situations where people at my level were making 1/3 or 1/2 what I was. I have also done the same and found people junior to me by quite a bit who were making more or less the same. Compensation is path dependent and somewhat random.
