Medical City of Dallas July 2015 Internship for the NICU

I interviewed with Medical City of Dallas summer RN internship for the NICU last week. I tried calling HR to see how long it would take to hear if I got the job, but they gave me another number to call. It was an automated line that gave me no information. I was wondering how long until others heard if they got the job?
I had an interview for the medical city children's section on Tuesday and got the call about accepting an offer the next morning by HR recruiter
