We totally have different backgrounds since I am a new grad and you are a seasoned nurse, but having been on a lot of panel interviews lately, I hope I can help you out. First, I want to say that you have a great work experience and a great set of skills! Go in there and be confident and show them what you got! I have some tips from my experience with panel interviews:
1. I always started off with a big smile, handshakes, introduction, and by saying I am super nervous but very happy to be there. That broke the ice and made the panel laugh. It eased the tension and helped make my interview more like a conversation.
2. I never rehearsed answers. No one wants to hear a robot and panels can tell which people have scripted answers. Be ready to talk about experiences that have demonstrated your critical thinking, leadership, and prioritization skills, but don't be wordy. Ask the panel questions, too! Don't let your interview become just an interrogation!
3. Remember that the people on the opposite side of the table had to interview for their jobs, too! They were in your shoes at one point.
4. Caution with the meds! I have never heard of anyone I know taking them for interviews but if you are going to, I hope you don't look drugged up on your interview day if that is the first time you are taking it!
Best wishes to you!
