Last I received was a confirmation email stating they received all of my documents. However, I got an offer elsewhere. Goodluck to you! I do know a nurse that works at St. Lukes who applied in March and got a call in August for interview.
In 2007, I applied from out of state. I didn't receive a call back until about a month before I graduated. I was a little afraid I was moving without a job. I had a phone interview (team interview) and was offered a job not too long after. I would just call the nurse recruiter and ask about the status of the residency application process. The nurse recruiter WANTS to recruit! Do not be afraid to call her/him!!
