Example: “Making a meaningful difference in the lives of my patients and their families motivate me to strive for excellence in everything I do. I look forward to seeing their reaction when we get a positive outcome that will change their lives forever. Like the family of a young boy we treated last year. At eight years old, he had experienced rapid weight gain and signs of depression. His parents described him as a usually joyful child, but now he seemed disengaged and uninterested in his typical schedule. In the end, we determined that it was hypothyroidism which is, of course, controllable with medication. The boy is adjusting well to the treatment and has returned to his joyful self. That’s why I became a nurse and why I’m pursuing a position in pediatrics.”
If you are currently employed, you should be honest about the start date and show professionalism. You should tell them you would have to discuss a transition with your current company to see if they require a two-week notice (or some other timing). If you currently have a critical role, your potential new employer would expect a transition period.
