Stanford Class of 2024 (entering 2020), Regular Decision

DS had his Stanford interview last week and was surprised by the questions interviewer asked him. He was asked what his test scores were, what other schools he applied to etc. Plus, the interviewer, a Stanford alum, was from a completely unrelated field and major . I’m not sure if this is more of an interviewer style or if Stanford provides guidelines a set of questions. Either way, DS was left scratching his head after the interview since none of his interviews with other schools. Any others have similar experiences?
