<p>Does the length of the interview really matters?</p>
<p>No, it doesn't.</p>
<p>it's just that normally a good interview takes longer because there is camaraderie and good conversation between interviewer and applicant. almost as if the applicant and interviewer have a lot to talk about and interest in keeping up that conversation.</p>
<p>normally a longer interview also leaves a more lasting impression or so i would think according to common sense.</p>
<p>Too long isn't good though. As long as there's good flow (meaning your interviewer doesn't have to pry information out of you), a longer interview is good. Some interviewers are in a rush though and some have lots of free time. Imagine yourself as an interviewer and ask what you would feel afterwards if you had just learned all you did from a stranger. The interviewer is the one who makes you look better/worse.</p>
