Some colleges and universities offer interview opportunities to prospective students. Often interview opportunities are limited to students who have submitted applications, which some schools offer them to all prospective students. For those colleges offering interviews, the degree of importance varies by school. Watch for interview opportunities and requirements for the schools on your college list—especially if those schools look for evidence of engagement or demonstrated interest.
College Kickstart, a popular college-bound site, compiled a helpful list of popular schools where interviews are required or strongly recommended, along with the degree to which the institution considers demonstrated interest as part of the evaluation.
