Interview tips

Hello everyone!!
Am new to this board and have read some great stuff. I know the interview process varies from program to program but am trying to get a handle on some universal do's & don'ts. I have interviewed twice and am on an alternate list. I have 3 years ICU experience, sat for the CCRN in May, had a 4.0 with my BSN. Also hold other members of the alphabet soup - PALS,ACLS and TNCC. Any suggestions for getting an edge, enhancing my chances for getting interviews? I didn't get a call from Minneapolis, anyone got the skinny on this program? What I haven't done: completed graduate course work or published a journal article. I know that I will get into a program, but as Paul sang "Oh, Cecilia.....your break'n my heart, your shak'n my confidence daily....."
Any input would be much appreciated.....
