Rady is all about their mission and "CARES" values. Include those in your answers. Also, take your time in the interviews. Ask them to repeat questions if you need to, a lot of the questions have multiple parts and you are scored on your answers so you don't want to miss anything.
A lot of personality/behavioral questions.
Feel free to message if you have more specific questions, I work in their PICU but know about the new grad program.
