My interview was also mostly EI with one clinical scenario. They asked me questions based on my experience (CVICU), medications, and basic vent questions.
Also got an invitation to interview. 2.5 years CVICU, CCRN, CMC, 315 GRE, 3.8 overall GPA, 3.6 science. I've done charge and preceptor. Fortunate that I am not restricted to my current geographical area and can apply to many programs to increases my chances.
