What makes it so great? The biggest of the Big Four accounting firms hires approximately 4,000 college grads each year to join its ranks of CPAs, actuaries, attorneys, and IT consultants as associates - with starting salaries averaging more than $50,000 a year. A behavior-based personality interview determines candidate placement. All new hires are mentored and, assuming satisfactory performance, are promoted within the first three years. But don't wait to apply until you graduate: PwC's internship program is a good way to get your foot in the door. Most of the 2,100 interns last summer were offered full-time jobs.
