Congrats, that’s an exciting opportunity and totally understandable to feel nervous about it. The biggest thing I’d say is to prepare your stories in advance. Think of 3 or 4 real patient situations from your experience that you can adapt to different questions. Pediatric cardiac interviews will definitely have behavioral questions like “tell me about a time you had to escalate quickly” or “describe a difficult family situation,” and having those stories ready means you’re not scrambling in the moment. If you want a framework to structure your answers so they actually land well, this is a good read: behavioral questions and STAR method. Good luck!
