I had 2 Interviews for the Graduate RN program- 1 with PCU, 1 with the Cardiac Units.
I applied online and received an invitation for a web-cam interview 4 days later. That part was easy. The app asks you basic questions ("Why do you want to work here", "Why nursing?", "What can you contribute?"). It allows you 2 chances to record responses, however, once you record the first response you cannot go back. Also, the responses are timed (30 seconds to think of an answer between 2 responses, if that make sense). I then received a call for an in-person interview w/ PCU a week and a half later. Luckily, the recruiters send you an email prior to your interview and are very thorough about what to expect, directions, etc.
Anyways, the PCU interview was the easier of my two. I was interviewed by 2 charge-nurses and they asked me questions like "Why would I want to work there?" etc. They also asked me case-scenario-type questions about chest pain, stroke patients, and diabetic patients. Once I provided them with nursing assessments and interventions (as well as some meds), they asked me to prioritize a list of patients based on condition. Truthfully, the case-scenario questions weren't too difficult. I then toured the unit with the charge nurse and that was that. Honestly, I thought I BOMBED my interview, but that's a whole other story (I ended up being offered a position..).
The interview for the cardiac floors was completely different and a lot more difficult!! I, first, interviewed with the HR recruiter (who asks you personality questions- why you "want to work there", i.e.). She was kind enough to prepare me for the panel interview by going over general, practice case-scenarios (my most memorable clinical and patient, a time that I "managed time wisely", conflict resolution, etc.). I was then escorted to an interview in which I sat in front of a panel of 6 cardiac charge nurses (all from different units- cardiac ICU, HF unit, cardiac cath. lab, cardiac PCU, etc.). I cannot lie, this was the most difficult interview! They went straight into firing off case-scenario-type questions (and they were VERY SPECIFIC). They asked me to recite the cardiac cycle (which is a must-know and is always asked, btw); they asked me a LOT about cardiac caths. (right vs. left caths, priority assessments ((check pulses)), retro-peritoneal hematomas, indications for cath & timing for procedures r/t MI's); they asked me about the drips I've seen and what the dosage for amiodorone was; they asked me about heparin & warfarin & what to monitor for (s/e and labs); ECG's, ETC.. It was very intimidating! My advice: STUDY UP AS MUCH AS YOU CAN ON CARDIAC (don't be caught off guard like I was).
Other than that, everybody I met was SUPER nice. Again, study before your interview(s) (case-scenario's; answers to those personality questions & clinical experiences)! Arrive up to an hour early (to find your way around & touch up on material). Bring multiple copies of your portfolio- I included a cover letter, my resume, my BLS/ACLS card, a letter of recommendation, and my certificates, as well as "sit pass" (they complimented that!). Dress professionally and BREATHE!
If you have any questions, ask your HR recruiter (they are awesome!). They'll give you tips/advice if you ask and will notify you as soon as they know whether you got an offer or didn't. And again, COME PREPARED! It was very difficult, but somehow I made it :).
Sorry if this was so long. I hope it helped!
Oh yeah, another piece of advice: Look over their mission statement & come prepared with a list of questions to ask them. Also, be honest with answers that you don't know. It is a graduate program, after all; so they are open to some gaps in knowledge. All of the managers I interviewed with said that they were looking for somebody who was "willing to learn"; so that was definitely a relief!
