How does this sound?
Dear Mr. ABC,
Thank you for taking the time out of your schedule to interview me about the registered nurse position at the..........Regional Medical Center. I highly appreciate your time and consideration. After speaking with you, I believe that I am a great candidate for this position, offering adaptability and strong desire to learn. I value how you manage your units in a combined fashion, making teamwork a strong priority.
I am very interested in working for you, this institution and caring for its patients. I look forward to hearing from you in the near future. Please feel free to contact me at any time if anything further information is need. My phone number is 000-000-0000. Thank you again for your time and consideration.
I changed things for identity purpose. The last line is something specific from the interview to make it more personal. The interviewer is the manager of four units (small hospital) and he told me how he operates them together so they are able to help each other with staffing and such so does that line make sense to any of you?
