Wow! ER at Grady as a new grad!!! You are a bold, challenge-facing woman!!! That personality trait should help get you through that panel review.
Think about it, you are pursuing one of, if not THE toughest ER position in the Atlanta. You are not being forced into this, you want it! Take that advice from above. You are interviewing them as well. Above all, don't lie. You have your experiences and that's what they are. If you are worried about a particular question, come up with the answer right now. Write down a number of these and answer them for yourself now without the pressure. You'll be amazed. It's like preparing for a test. And, in the likely chance that they ask you a question you don't know the answer to, tell them the truth. Tell them, "You know, I don't know. But, that is one of the reasons I want to work at Grady. I know that I will learn so much here. (And if applicable) In the mean time, I am certainly going to go home and look that one up!" Nurses and managers are the most terrified by new nurses who think they know everything and/or don't ask questions.
I went through something very similar at St. Joe's. I work in the CVICU now and started there as a new grad without ANY ICU experience. In fact, the only in depth experience I had was L&D (thus my screen name). I was trying to get into one of the most selective new grad programs in the Atlanta metro area. Even the nurses I work with now are amazed when they learned I was a new grad when I started there. Most said they couldn't have done it. But it was a grand challenge for me and I made myself rise to the occasion.
I see you as doing the same thing. You're stressing because you want it!!!
It's in you. :pumpiron: You'll do fine. And, if for some reason you don't, there are hundreds of other jobs out there just waiting for you.
