Use your "go-by" name. That is, if everyone knows you by a nickname or your middle name, use it. For example, Katherine Elaine Johnson – if everyone calls you Kate – you can use KATE JOHNSON on the top of your resume, if everyone calls you Elaine – use ELAINE JOHNSON or K. ELAINE JOHNSON.
List any professional credentials (M.D., CPA, Ph.D.) that are appropriate for the job sought. If they are not related to the opportunity for which you are applying, do not include.
