How carefully do B-schools consider last 2 years undergraduate GPA?

Say Person A has a 3.2 overall, and a 4.0 last 2 years GPA. How important is this to Top-50 B-schools?

More important is the full time job you have had since you graduated. You do realize that most top MBA programs require at least 2 years of full time post bachelor’s work experience?

I know, yes. What type of job is best? How important is it for it to be a large company vs. having management experience?
