I just interviewed at Northside for a new grad position. They said they start nurses at 22.54 base pay. The differential for weekend is 3.00/hr and 5.00/night, but I think that starts after the 12 week internship. The recruiter said they are a bit higher than other hospitals but not much. It's going to be anywhere from 21-22 base/hr.
You can also visit some of the hospital websites and search the position to find the min and mid. I believe Emory and Gwinnett Medical Center lists that information. But the previous poster was correct with the rate range. Weekend option only, if offered, tends to pay a little more and shift differentials can vary by hospital.
