They could be different. Current job obviously changes over time. It's not a good idea to automatically update applications that were already submitted/reviewed after changing job.

Degree is more a toss-up, though I can still make the argument that some jobs may only care about advanced degrees, and some may want even high school degrees, so degrees are not the same for every application.

Ultimately it's about the tradeoff between customization and convenience. Putting them in User is better for convenience because the user doesn't need to re-enter them for every application, but putting them in Application gives the user more flexibility to customize each application. Because preparing a job application is usually a meticulous task that one doesn't do all that often, I'm leaning toward customization.
