My daughter had an interview with the same person you had (your hints were enough for us to figure it out). It was the only bad interview she had and it was because the interviewer attitude.
That took away all her enthusiasm for the school (it was her dream school before the interview). I think if she gets in and has other options she would rather go somewhere else.
I think a top school like that should learn about the experiences they are creating. They should send evaluations to applicants after M10.
