I’ve heard that for competitive schools a good interview won’t help you much but if you messed up the interview it will decrease the chance for getting in. Is it true? If no then how much impact will it has on admission process (especially for people like me who don’t have very high gpa but special in some area)?
Did you check the college website to see if the interview is informational (doesn’t count) or evaluative (counts)? Is it an alumni interview or an interview with an admissions officer?
