Curious, I note from the US News rankings that the Ivy League dominates the top architectural schools. The only ones that break up that dominance are MIT (kind of a distinction without a difference) and Rice.
I’m sure she was very knowledgeable, and has gone on to blame your job offer on the Patriarchy and mysogeny. :-)
But, to your point, yes, there is no place where the educational matter is more irrelevant than in the professions that work on billable hours. The client will always want to see resumes which are big on the person’s achievements, years working on similar projects, and of course in the case of architecture, the actual portfolio, before they commit to an hourly rate.
The university they went to is somewhere off in the distance. I wouldn’t think that most of the people hiring for high-end architecture projects even KNOW that Yale is ranked 2nd in the nation for that major.
And if they know, I’m sure they don’t care. :-)
