Interviews--Do only certain applicants get them?

<p>I have two friends at my school that applied to Columbia, and only one of us has been contacted for an interview. Are applicants chosen at random to be interviewed? Are applicants who the admissions committee are on the fence about more likely to be interviewed? Thanks.</p>

<p>each school has its own policies. For columbia, i think its random due to the high demand of interviews.</p>
