I would see university admissions as a closer comparison than university tests. If I'm applying to jobs (or universities) I'll want to apply to several in case some don't accept me, some feel like a bad fit once I'm in the process, etc. I won't want to cram for each. I'll want to reuse the same cover letter or admissions essay to the extent possible. Once I'm in the university and enrolled in classes, I'll know what to focus on and I'll be willing to study hard for tests. I know some people see it differently, but I've always considered multiple potential employers simultaneously and I definitely haven't been willing to play the "devote weeks of your life to try to get hired by a specific company" game. On the other hand, some people find that worthwhile, and more power to them.
