@COH123: By applying.
Not particularly hard if you get a decent GPA and some interview skills. Another factor is the percentage hired from your school vs other schools in the area, this helps a lot. They do not necessarily just pick who they feel is best amongst all schools. They try to select a certain number of hires from specific schools.
It is a lot easier to get in PwC/KPMG/EY. For reference see statistics on interns hired, and full time hired vs applicants (may have to adjust total applicants accordingly as it includes its consulting business).

3.2 at UVA is decent I guess, there are a lot of factors in the hiring process. But it's about the minimum, it'd say the complete cutoff is 3.0. 3.5+ is a very safe bet.
