Neither the question "How do you do?" (antiquated or extremely formal) nor, normally, the question "How are you?" is directly answered at first-time meetings.
Native speakers of English have little time for titles. For instance, the title “Doctor” is normally just given to a GP (not to specialists or dentists) as well as to scientists in certain contexts, but not to lawyers, for instance. For men, we use “Mr”, for women “Ms” [Miz]. Never introduce yourself with a title!
