I think it depends on the job for which you're applying.
We want our senior developers to be willing to dig into business requirements and constraints without being asked to. Curiosity, orthogonal business knowledge, etc are important at that level and higher.
However, we've seen multiple times that the junior developers just can't do it with the rare exception. They have enough work getting up to speed on one or more of: the language, the large internal system, the large client systems, how the client works, how to be an employee, how to deliver value over the long term and not go 2 weeks with no delivery then 2 weeks with, etc.
