If you're joining a company of 15 people? Probably. If you're joining a company of 50,000? Absolutely not, because they're not going to vastly increase the complexity of their HR or payroll just to close a single hire.

Money and equity are easy to negotiate because there's no management overhead. But if you want your 401k to be at a different brokerage, or have other "process" request like that? Probably not gonna happen - not for a line employee.
