<p>Interviews only go as far as if you're an outgoing person with a charismatic personality. If all you are able to do is give a negative impression, it's better off not asking for an interview.</p>
<p>But I guess the best way to prepare an interview would be ask one of your senior friends to do a mock-interview. That's what I would do. But I think people who give good interviews just have a knack for it. They're able to project themselves and are capable of making a lasting impression, a good one.</p>
