<p>if your interviewer is really young (22-25) should you address him/her by his/her first name or ms.<strong><em>/mr.</em></strong>___?</p>
<p>What context are you seeing this individual? Are you in HS & therefore 17/18? I’d ask the interviewer at the beginning how they would like to be addressed. “I’m John Interviewee. How should I address you, please?”</p>
<p>I’ve found that younger interviewers usually ask you to call them by their first name after hearing you call them Mr. or Ms. the first time. So if they don’t tell you to begin with, go with the formal address, so they can correct you if they’d prefer to be more familiar. Better to have them ask you to call them by their first name than for them to be offended if you automatically assume to address them in a familiar way.</p>
<p>Start with mr. or ms. and if they tell you to address them by something else, do so. If they don’t say anything about it, that means they are fine with the way you are addressing them.</p>
<p>When you’re meeting an adult for the first time it’s generally a good idea to address them by their last name with the appropriate title (Mr., Ms., Dr., Senator, etc.), after which you may or may not be able to switch to using their first name. If the interviewer would be prefer to be called by his or her first name, he’ll let you know.</p>
<p>However, in cases where you’re being interviewed by a current student (often a senior), I’d recommend using the interviewer’s first name, as they’ll be quite similar in age and most college students find it odd when other college-age people address them by their last names.</p>
