I would recommend a suit. Choose a conservative color, preferably grey or navy blue. Get a suit you feel confident in. A pump with a low heel . Hair should be very neat. Get a haircut if you need one. Keep the jewelry to a minimum, or better yet, none at all, or a wedding band only. Nails. Keep them short and neat with a coat of clear polish. Makeup. Keep it minimal. Let your natural beauty shine through. Bring all of your credentials with you in a blue folder. Resume, Transcripts, professional references, letters of recommendation, nsg license, BLS, ACLS. Smile. Shake your interviewer's hand at the beginning and end of the interview. Maintain eye contact. Did I say smile? Oh, get a thank you card, fill it out immediately after the interview while its still fresh in your mind. Take it back to the interviewer and thank them again. GOOD LUCK!!!!
