I too came to nursing after a career in law/business. My mom has been in HR for 35 years, I stopped taking her advice for interviewing, because she doesn't understand how different it is interviewing as a nurse. I have gotten an offer for ever nursing and NP job I've applied for. My advice is to be professional and articulate, and let that speak to your basic abilities and skills. Spend your time during your interview talking about (and giving examples) of how you are a team player, what being a nurse means to you, how you want to affect the lives of your patients, how you see yourself progressing from a novice to an experienced nurse.
When it comes to a question like where do you want to be in 5 years, I think a softer answer is better. "Career advancement" in nursing is so different from the corporate world. It does not reflect negatively on you if you want to be a bedside nurse for the rest of your life. Nor is it expected that you will be. But your opinions will likely change as you transition from a student to a nurse, so I think it could be seen negatively to have such a concrete answer. I think an answer that focus more on the fact that you want to keep learning and developing as a nurse, and that you definitely are interested in pursuing a graduate degree in nursing. That makes you seem more open and flexible. Both qualities are essential to nursing.
If you are close to any of your nursing faculty maybe ask if they would be willing to do a few mock interview questions with you. They may be able to give you more feedback on non-verbal attitude and things that you might be conveying that you don't realize. Good luck with your job search
. Please let us know how it goes if you get an interview for the residency position.
