IMO very few top-tier school if any will accept a person with NO job experience regardless of gpa or scores. This is because part of the education as such school is the sharing of experiences among peers.
Second tier and below school are not so particular, but you chances are better with ALL schools if you have about 4-5 years under your belt.
