From CALS Admissions page; “Although CALS does not conduct personal interviews as part of the application process, a campus visit is strongly encouraged.”
No, only SHA and AAP require interviews as a part of their admissions. All other Cornell schools do not require them. In fact, it says so on their website. If you are offered one from a Cornell Alumni Ambassador Network (CAAN) it is informational only and has no bearing on your application.
