So let's say I am hired by a startup and I am getting half the industry salary rate for my role. What kind of "stock/share/esop/options" I should ask for that changes like a founder's would? Of course it will be a lot less than the founder's (and it will be fulfilled in stages) but iff, let's assume, I want to get that "kind" of "share" of that startup what it would be? Is there a specific term for it? Or it varies from company to company? Unless it it's public where's it's the "share", right? edit: any recommended reading on this?
